Galaxy Birthday Cake

A stunning Galaxy Birthday Cake decorated with swirls of cosmic colors, shimmering stars, and edible glitter, perfect for space lovers and special celebrations.

Ingredients

Scale
  • 2 ½ cups all-purpose flour
  • 2 ½ tsp baking powder
  • ½ tsp salt
  • 1 cup unsalted butter, softened
  • 2 cups granulated sugar
  • 4 large eggs
  • 1 tbsp vanilla extract
  • 1 cup whole milk
  • 3 cups buttercream frosting
  • Gel food coloring (black, purple, blue, pink)
  • Edible glitter and star sprinkles

Instructions

  1. Preheat oven to 350°F (175°C) and grease three 8-inch round cake pans.
  2. In a medium bowl, whisk together flour, baking powder, and salt.
  3. Cream butter and sugar until light and fluffy. Beat in eggs one at a time, then stir in vanilla extract.
  4. Alternate adding the flour mixture and milk to the butter mixture, beginning and ending with flour. Mix until just combined.
  5. Divide batter evenly between the prepared pans and bake for 25–30 minutes or until a toothpick inserted comes out clean.
  6. Cool cakes completely before frosting.
  7. Tint the buttercream with galaxy colors (black, purple, blue, pink) and spread them randomly on the cake. Use a spatula to swirl the colors together to create a galaxy effect.
  8. Decorate with edible glitter and star sprinkles to finish the cosmic look.

Notes

  • You can use chocolate cake layers for a darker base that enhances the galaxy look.
  • Chill the cake before decorating to make frosting easier.
  • Gel food coloring is recommended for vibrant hues without thinning the frosting.
