Mirror Glaze Galaxy Cake Recipe
Do you also adore that pretty Mirror Glaze Galaxy Cakes which infect the world for a while but are intimidated to try it on your own? I know what you mean, you are not alone.
But trust me. It is totally worth to try to make yourself such a beautiful Mirror Glaze Galaxy Cake. I guide you through every single step to make sure that you succeed and end up very happy. It’s a fun project you shouldn’t miss.
You will learn for life. There are plenty of situations where we would love to make pretty cakes for friends and family, right? Once you know how to handle a mirror glaze, you can use it for many other baking ideas. Glaze cake pops, chocolate mousse, and ice cream cakes, in every color you want. A world full of opportunities opens up.
Cake Pop Planets
Ok, let’s jump into the recipe. We start with the cake pop planets. I chose the Sun, Earth, Uranus, and Neptune for my Mirror Glaze Galaxy Cake because their colors are the prettiest ones to me. We have yellow and red for the Sun. Green and blue (and white if desired) for the Earth. Teal and white for Uranus and purple with white for Neptune.
Add as much coloring as described on the package until you reach the color you desire. You can use gel or paste food coloring. I added a bit of white to every color to brighten up the color of the batter.
I recommend using a silicone cake pop mold for baking the planets. Spoon the colored batter alternately in the mold and give it a few swirls. Fill up until very slightly heaped.
I decided to make a white cake because it is very bright and perfect for coloring and it has a great vanilla flavor. The recipes of the cake pops and the cake are straightforward to make sure to have full focus on the styling today.
Separate the batter into 4 bowls, 2 big ones, and 2 small ones. Add black and white to the two big ones. Pink into a small one and Aztec blue in the other small one. Lighten up with white if needed.
Alternately, spoon about 1/4 of the colored batter into two 8¨ baking pans just until the bottom is fully covered. Divide planets in both pans and place them in the batter. Spoon remaining batter on top of planets. Swirl carefully to draw a pattern.
Galaxy Vanilla Buttercream
The vanilla buttercream is also pretty straightforward. You just need to mix butter with powdered sugar, then add vanilla, milk, and salt. The salt will cut down the sweetness a bit.
Place the bottom cake layer with a cake board underneath on a turner. Then pipe buttercream on top of the bottom layer and smooth with a big offset spatula. Place the edge of the spatula horizontal on top of buttercream and spin cake around until it is leveled. Place top layer on top and frost the cake.
Pipe buttercream on top and the sides. To level the buttercream on the sides, plant the spatula next to one side uprightly and spin the cake around. Take care that you keep the same angle while spinning the cake around.
Smooth the edges by leveling the top again and push frosting very slightly and carefully to the edges. Then level the edges from the sides again and repeat until edges are smoothed.
Freeze cake for 1 hour until buttercream is very firm. This makes sure that your cream isn’t melting away while glazing the cake.
Galaxy Mirror Glaze
This is now the most exciting part of making a Mirror Glaze Galaxy Cake. It is super, super thrilling.
How will be the consistency? How will be the pattern? These are questions what will be running through your head when you make your first time a mirror glaze. But keep cool. Watch the video. I show how to glaze the cake that it turns out really beautiful. Just follow the steps in the recipe and the video.
You did a great job so far. You will rock the mirror glaze too!
For the mirror glaze I used the following colors: black, navy blue, Aztec blue, purple, pink, white. I also used black pearl dust.
Strain and divide mirror glaze in 5 bowls. 2 big bowls and 3 small bowls. Add Aztec blue and navy blue in the ratio 3:1 in one of the two big bowls. Add black and navy blue in same amounts in the second big bowl until you reach a very dark blue tone.
Add pink, purple, and a bit of Aztec blue (teal tone) to the 3 small bowls. Add a bit of white if anything is too intense to lighten up the colors.
Line a cookie or baking sheet with parchment paper. Place a vase upside down in the middle of the sheet and place the cold cake on top.
The glaze needs to be 90°F / 32°C that it is not too thin and not too thick. Use a candy thermometer. When your glaze is too hot, let it stand until it cools down a bit. This will go very fast. Otherwise, the glaze doesn’t stick to your cake and is too runny. When the glaze is too cold, it is too sticky, and you can’t pour it over your cake. In this case, warm it up in the microwave for a few seconds.
Pour the blue from the first big bowl into the very dark space blue in the second big bowl. Give it a few gentle swirls but don’t mix up the colors. Pour over cake beginning on the top and then let drip over the sides until the cake is fully glazed.
Drip with a spoon a few lines of teal, purple, and pink on top. Go with the lines of the light and dark blue pattern. Smooth colors carefully by brushing with the big offset spatula over the top of the cake. Go with the lines on the cake.
Sprinkle a bit of black pearl dust and white food coloring on top with a brush. The galaxy cake will be even more beautiful.
Congratulations! You are a proud owner of an amazing looking homemade Mirror Glaze Galaxy Cake. You did a great job. Woohoo. Let’s do the happy galaxy dance.
Looking back, it was exhausting, on some points overwhelming, super exciting, thrilling, we had a lot of fun, and it was just a special, not everyday project.

so so so beautiful
fun and exciting
Happy galaxy cake baking!

Microwave butter for about 15-20 seconds until very soft and a bit melted. Set aside.
Preheat oven to 350°F / 175°C.
With a handheld or stand mixer fitted with a whisk or paddle attachment, mix eggs on medium-high speed until combined for about 1 minute. Add sugar and mix until light and creamy for about 2-3 minutes. Add butter and mix until creamy. In the end, add flour, baking powder, and salt and mix until fully combined and smooth.
If you want to make the same planets like me, separate batter in 6 bowls and color with navy blue, purple, green, Aztec blue (teal tone), yellow, red, and white. Use gel or paste food coloring. Depending on your food coloring brand, add a few drops to your batter until you reach the desired color.
If you want to use more of one color and less of another, consider the required amount of batter per color while separating into bowls. I added to every portion a bit of white to lighten up the colors.
Use a 20 cake pop mold. Spoon red and yellow batter into a few mold for the sun (the side of the mold without the holes). Blue and green (with a bit of white if desired) for the Earth, teal with a bit of white for Uranus, and purple with a bit of white for Neptune. Fill until level with a very slightly heaping and draw a few swirls with a skewer. Place the second side of the cake pop mold on top (the one with the hole) and close tightly.
Bake for about 18-20 minutes. I baked mine for 20 minutes. Let cool in the mold until you are done with the cake batter. Set aside.
Line two 8-inch baking pans with parchment paper by cutting 8-inch circles for the bottom and about 2-3 inch wide strips for the sides. Use very less baking spray underneath the paper that it sticks to the pan for easier filling.
In a small bowl, whisk milk and egg whites until combined. Set aside.
In another small bowl combine flour, baking powder, and salt and stir to combine. Set aside.
With a handheld or stand mixer fitted with a whisk or paddle attachment mix butter and sugar on medium speed until creamy and combined for about 1-2 minutes. Add vanilla* and mix until combined. Mixing on low speed, alternately add dry and wet mixtures, beginning and ending with dry ingredients. I added the dry ingredients in 3 batches and the wet ingredients in 2. Mix until smooth and combined.
I used 4 colors for the galaxy cake batter. Black, white, pink, and Aztec blue (teal tone). Divide batter into 2 big and 2 small bowls. Add black food coloring and white food coloring in the two big bowls and pink and a bit of Aztec blue in the two small bowls. Add white if you want to lighten up the colors.
Spoon about 1/4 of the colored batter alternately in the two pans equally until the bottom is covered. Gently draw a pattern. Be careful that you don't mix up the colors. Place 10 cake pops planets in each pan. Spoon remaining batter on top of the planets.
Bake for about 27-30 minutes until a toothpick centered in the middle comes out clean (don't pick inside a cake pop). Let cool in pans for about 10 minutes then transfer to a wire rack to cool completely.
Galaxy Vanilla Buttercream
Mix butter with a whisk attachment on medium speed until creamy for about 2 minutes. Add 1 cup sugar at the time and mix on low speed until combined. Add salt and mix to combine. Mix in vanilla* and milk until smooth and fully incorporated. Divide buttercream into 4 bowls. I used black, white, blue, and pink. Add white to lighten up the colors if desired. Spoon the colored buttercream alternately into a piping bag.
Frost the cake
Place bottom cake layer with a cake board underneath on a turner. Pipe a thin layer of buttercream on top. Even with a big offset spatula by placing the edge of the spatula on top of the cream horizontally and spin the cake around. Place the second cake layer on top. Pipe remaining buttercream on top and the sides until the cake is fully covered. Level the top with the spatula like you did with the bottom cake layer until buttercream is smooth and even.
To level the buttercream on the sides, plant the spatula next to one side uprightly and spin the cake around. Take care that you keep the same angle while spinning the cake around. Smooth the edges by leveling the top again and push frosting very slightly and carefully to the edges. Then level the edges on the sides again and repeat until edges are smoothed.
Freeze cake with the board underneath for about 1 hour that the buttercream is very firm and doesn't melt away while glazing.
Galaxy Mirror Glaze
Add ¾ cup of water and gelatin in a small bowl and stir to combine. Let bloom for about 10 minutes. It needs to be firm to touch.
Place chopped couverture in a big bowl and set aside.
In a small saucepan bring sugar, 3/8 cup water, and corn syrup over medium heat to a boil and simmer for about 2-3 minutes. Remove from stove and stir in bloomed gelatin and condensed milk until combined. Pour over couverture, cover with a towel and let stand for about 2 minutes.
Mix with a handheld emersion blender until smooth, and no lumps remain. Strain and separate mirror glaze in 5 bowls. Two big ones, and 3 smaller ones. Add Aztec blue and navy blue in a 3:1 ratio in one big bowl. Add black and navy blue in equal amounts to the second big bowl. In the 3 small bowls, add purple, pink, and Aztec blue (teal tone). Add white to brighten up the colors if needed.
Glaze the cake
Line a cookie or baking sheet with parchment paper. Place a vase upside down in the middle. Remove cake from the freezer and place on top of the vase.
The mirror glaze needs to be 90°F / 32°C while glazing that it is not too thin and not too thick. Use a candy thermometer. When your glaze is too hot, let it stand until it cools down a bit. This will go very fast. Otherwise, the glaze doesn’t stick to your cake and is too runny. When the glaze is too cold, it is too sticky, and you can’t pour it over your cake. In this case, warm it up in the microwave for a few seconds.
Pour the blue from the first big bowl into the very dark space blue in the second big bowl. Give it a few gentle swirls and draw a pattern. Don't mix up the colors. Pour over cake beginning on the top and then let drip over the sides until the cake is fully glazed. Drip with a spoon a few lines of teal, purple, and pink on top. Go with the lines of the light and dark blue pattern.
Brush with a big offset spatula over the top of the cake to smooth the colors. Sprinkle a bit of black pearl dust and white food coloring on top of the cake with a brush.
Let dry for about 1/2 hour then transfer to the fridge and chill for 2 hours. Cut cake with a very warm knife (warm with hot water then dry) for best cutting results. Store leftovers in an airtight container in the fridge up to 3 days.
*First, cut off the straight end of the vanilla bean. Then place the tip of your sharp knife below the curled end and cut the vanilla bean through the middle of the bean lengthwise. Although you don't need to cut it all the way through, it's ok when you do so. Then open the vanilla bean and scrape out the flavorful seeds with the back of your knife. Just use the seeds.
Thank you Thank you! I am so not a baker, I can’t ev n frost a cake and write happy birthday on it without our it looking like a toddler did it! But my son wanted this cake for his 13th birthday, so my I tried it out. I thought it was going to be a disaster, but it turned out really good! Your directions were so easy to follow, even for someone who usually has a hard time understanding recipes. I have pictures of mine, but don’t know how to upload.
Thank you so much for your feedback, Jessica! I’m so happy that it was a success! You can share your photos on your Instagram account. Please tag me in the photo that I can see it ?? Have a wonderful day!
Hi Sabine, I’m absolutely in love with your creation here and have gone through your video again and again. I had recently made a moist chocolate cake for my son’s birthday party ( 30 kids and 40 adults) and the guests loved it. A Friend of mine asked me if I could bake a cake for her daughters birthday party. I’m Glad to do it. Now, it’s a outer space themed party of 40 kids and 35 adults. After some research, I found your cake the best of all and want to make it without any doubts. I really don’t want to disappoint her since it’s a big party for her and she has trusted me on this ( I’m not a professional baker) My worries are: 1) Can this be made with the moist chocolate cake recipe? 2) She needs a 4 kg cake ( about 70 medium sized servings; there will be cupcakes and cake pops too) So , can I make a 2 tiered moist chocolate cake and hope it holds up and doesn’t collapse? She’s keen on moist chocolate cake. 3) can I do a 9” for base tier and a sphere globe cake for the second tier? Will it hold up?
I’m very sorry about the Long post, but thought it’s best to explain the thing for your understanding.
Hi Supriya, Thank you so much for your feedback! I’m happy that you like it. 1) Yes, absolutely. But consider that the chocolate batter won’t allow you to color it as much as a bright cake. Maybe you make a white chocolate cake? 2) Okay, so you really should do a chocolate cake when it’s her favorite. I’m so sorry but I have no experience in baking such big and high cakes. If the cake is too fluffy I can imagine that it’s not that stable and could collapse. I think Google research would help you with this. 3) I’m sure it looks cool to place a globe cake on top of a base cake. But same as at 2). I really can’t say anything to this. I just could guess because I’ve never done such a cake shape before.
This is amazing and an awesome work of art. I was looking for a recipe for my nephews “outer space” themed birthday and I think this is the perfect cake. I can’t waot to recreate it. I also had a quick question. I was thinking of making a 6 inch cake instead of An 8. How do I tweak the ingredients? It would be really helpful. Thanks Anisha
Thank you so much! I’m sure he would love this cake for his birthday! Although I haven’t tried this recipe in 6 inch pans, I would go with 2/3 of the ingredients or better would be 3/4 but that doesn’t work out with the eggs. So yeah, I would go with 2/3. Hope that helps! Happy baking (:
Recipe worked like a charm, I was nervous about the mirror glaze but it turned out great! *I did end up with a bubble in the mirror glaze but I had to store the finished cake in the fridge so I think that’s why that happened.
*I do agree with the other comment about the cake tasting like corn bread, I made the planets and tasted them and decided to use a box cake mix for the cake and it turned out perfect. I also used cream cheese frosting instead of buttercream.
I made this and it turned out beautiful! The taste however was not so great. It tasted more like a mild corn bread than a cake. I sadly will be tossing it! ?? Note sure if I did something wrong? I think I will try a different cake recipe next time with your decorating and color techniques! Thanks for posting.
Hi Madison, I’m happy that it turned out beautiful but also sorry to hear that the cake is not your taste. Although I can’t say if you did something wrong, keep in mind that every taste is different. It does not taste like cornbread to me. I think the cake is very sweet. Thanks!
My daughter has chosen this glorious cake for her 21st birthday ??!!!!!! I have attempted the cake today…..disaster has struck, the cakes are so much thinner than the beautiful cakes you made. The cakes also smell a little eggy….please note I’m making this in England, is the flour, plain or self raising? I’d be very grateful for some pointers as the recipe was followed…..where did I go wrong.
I’m sorry to hear that! It sounds like you had too much egg in the batter. Maybe your eggs were extra large, I always use large eggs but medium eggs would work fine too with this recipe. This would explain why the batter is thinner because there is more liquid in it. The cake should not smell eggy. Other than that it’s just possible that there was a mistake with measuring of the flour or other ingredients. I always use all-purpose flour (plain). Hope that helps! Otherwise reach out to me again, that I can help you!
I just made this, and it turned out exactly like the photos. I broke it up over a 2-day period because I was trying to do a good job without being rushed. I was very worried that something would go wrong, since there were so many steps and opportunities for disaster. Your recipe works as written, which is a rarity! Thank you so much for sharing this. I’m looking forward to more mirror glaze projects now that I know what to expect.
Nichole, I’m so happy that it turned out great! Thank you so much for your nice feedback, I really appreciate it! I know exactly what you mean. It is a very good strategy to break it up over two days because the mirror glaze is the trickiest part. It’s good that you take your time. Happy mirror glaze baking ??
Hello Sabine, First, let memtell you that your cake is super creative and stunning! I’ve been trying to make mirror glaze cake 3 times by using the recipe that doesn’t require corn syrup. I failed everytime. However, I’m wondering how the texture of mirror glaze after being poured and set on the cake should be like. Mine was rubbery and a bit thick and it separated from frosting. But your glaze seems to be very thin and stick with the frosting. Any advices why? I’m going to try your recipe in hope that I’ll be successful in doing this. If I don’t have a hand blender, can I just stir until the white chocolate completely metls?
Hi Kampu, Thank you so much! I’ve found a great resource that describes the consistency of a mirror glaze perfectly https://www.cupcakeproject.com/whats-the-deal-with-mirror-glaze-cakes/ I really recommend a hand blander over a whisk because it makes the glaze smoother and it would take too long with a whisk so the glaze would cool too much. Hopefully, that helps!
Microwave cooking and nutrition
Are microwaves bad for your health? Almost every American house has a microwave. The convenience they offer is undeniable. However, despite the widespread use of microwave ovens and excellent safety recordings, some people suspect that cooking microwaved food makes it somewhat less healthy by removing foods from eating. Do you cook with microwave? Are microwave foods healthy?
How does microwave cooking work?
Understanding how microwave ovens work can help clarify the answers to these general questions. Microwave ovens cook food similar to radio waves but using shorter energy waves. These waves are highly selective, mainly affecting water and other electrically asymmetrical molecules - one end is positively charged and the other is negatively charged. Microwave ovens cause these molecules to vibrate and rapidly generate thermal (heat) energy.
Are microwaves safe to cook?
Some foods, when they are exposed to heat, from a microwave oven or a normal oven, are broken down. Vitamin C is perhaps the most clear example. However, since microwave cooking times are shorter, cooking with microwave does a better job of preserving vitamin C and other nutrients that are decomposed when heated.
When going to the vegetables, cooking in water takes some of the nutritional values ??because the nutrients flow into the cooking water. For example, boiled broccoli loses glycosinolate, a sulfur-containing compound that can give vegetables the ability to fight against cancer (and many find it distinctive and some find it disgusting). Steaming vegetables - even steaming microwave - is it better? In some ways, yes. For example, steamed broccoli holds more glucosinolate than boiled or fried broccoli.
Are microwaves bad for your health?
The method of cooking, which keeps the nutrients in the best way, is a method that quickly heats, warms food and uses as little liquid as possible. The microwave meets these criteria. Using the microwave with a small amount of water evaporates food from the inside out. It contains more vitamins and minerals than almost all other cooking methods and shows that microwave foods can be really healthy.
But let's not get lost in details. Vegetables are good for you in any way you prepare, and most of us don't eat enough. Is the microwave oven good or bad? Microwave is an engineering wonder, a miracle of convenience - and sometimes advantageous in feeding.
