# How to Make It:

01 - Preheat oven to 350°F. Grease and line three 8-inch round cake pans with parchment paper.
02 - In a medium bowl, whisk together flour, baking powder, and salt until evenly distributed.
03 - In a large bowl, cream butter and sugar together until light and fluffy, approximately 3-4 minutes.
04 - Add eggs one at a time, beating thoroughly after each addition. Mix in vanilla extract until combined.
05 - Alternately add flour mixture and milk to butter mixture, beginning and ending with flour. Mix until just combined to avoid overdevelopment.
06 - Divide batter evenly among prepared pans.
07 - Bake for 25-30 minutes until a toothpick inserted into the center emerges clean.
08 - Cool cakes in pans for 10 minutes, then turn out onto wire racks to cool completely.
09 - Beat butter until creamy. Gradually add powdered sugar, milk, and vanilla extract. Beat until smooth and fluffy.
10 - Divide buttercream into four separate bowls. Tint each with different galaxy-inspired colors: navy blue, purple, teal, and black.
11 - Place alternating spoonfuls of each colored buttercream onto cake layers and sides. Use offset spatula to swirl gently for celestial effect.
12 - Sprinkle edible glitter generously over cake surface. Add fondant zodiac symbols or stars as desired.
13 - Chill finished cake for 30 minutes to set the decorative design before slicing.

# Expert Tips:

01 -
  • It's actually forgiving—the swirls are supposed to look imperfect, which takes all the pressure off your decorating skills.
  • The vanilla sponge stays moist for days, so you can make it ahead and assemble when you're ready to play with color.
  • Watching people's faces light up when they see edible glitter catching the light makes every minute of work worth it.
02 -
  • Room temperature is the secret your grandmother probably tried to tell you—it's not fussy, it's physics, and it changes everything about how ingredients marry together.
  • Edible glitter sticks better to frosting that's slightly tacky; if your frosting is too cold and firm, the glitter will slide right off.
03 -
  • Use gel food coloring instead of liquid—it's concentrated enough that you only need a toothpick dab, and it won't thin your frosting or make colors muddy.
  • If your frosting looks broken or curdled while mixing, it usually means ingredients were too cold; let everything come to room temperature and try again, and it'll smooth right out.
