For Noelle’s “Stay Wild Moon Child” themed 30th birthday, I promised her an out-of-this world cake. When I realized I committed to making a fondant covered, sponge painted creation (both of which I have no experience with) I found myself searching for a solution. “Galaxy” donuts have been a thing lately, so I decided to use donut glace icing for the cake frosting. With a little bit of pixie dust, this cake turned out sparkling and better than I could have imagined!


Galaxy Cake
2 boxes Devil’s Food cake mix
2-1/2 cups water
1 cup vegetable oil
6 eggs
Star sprinkles
Black food coloring
2 containers of store-bought buttercream frosting


  1. Heat oven to 350°F
  2. Make cake according to the directions.
  3. Pour cake batter of first 2 layers into 2 9” pans that have been greased.  Sprinkle with star sprinkles.
  4. Bake approximately 30 minutes at 350°F or until you can put a toothpick in the center and it comes out clean.
  5. Repeat with remaining 2 layers.
  6. Cool all layers completely at room temperature (~12 hours).
  7. Level with cake leveler and discard one layer (or reserve, but you do not need it. I always bake 4 layers and pick the best 3).


  1. When ready to serve, spread frosting between each layer. Top with glacé icing (below).



Glacé Icing
From Whisk and Wander
2 pounds confectioners’ sugar, no need to sift
1/4-3/4 cup water, room temp
1/2 teaspoon almond extract
Blue, red and black food coloring
Silver pixie dust (optional)

  1. In the bowl of a stand mixer fitted with the whisk attachment add confectioners’ sugar.
  2. With mixer on low speed slowly add water to sugar a little at a time until icing is spreadable but not too thin.
  3. Mix until all sugar is dissolved and icing looks smooth. About 4 minutes. Scraping sides as necessary.
  4. Slowly add food coloring and swirl with fork.  I started with a couple drops of blue, a few red (to create purple) and a tiny hint of black.  Swirly gently to create the galaxy effect.
  5. When desired color has been achieved, pour slowly pour over cake to ensure maximum coverage.
  6. Spread around sides to completely cover cake. Top with silver pixie dust for additional shimmer
