→ Decoration

15 - White fondant (optional, for zodiac symbols or stars)
16 - Silver star sprinkles (optional)

# How-To Steps:

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. Set aside.
03 - In a large bowl, cream together butter and sugar until light and fluffy, approximately 3-4 minutes.
04 - Add eggs one at a time, beating well after each addition. Mix in vanilla extract.
05 - Alternately add the flour mixture and milk to the butter mixture, beginning and ending with flour. Mix until just combined.
06 - Divide batter evenly among the prepared pans. Bake for 25-30 minutes, or until a toothpick inserted into the center comes out clean.
07 - Cool cakes in pans for 10 minutes, then turn out onto wire racks to cool completely.
08 - Beat butter until creamy. Gradually add powdered sugar, milk, and vanilla; beat until smooth and fluffy.
09 - Divide buttercream into four bowls. Tint each with different galaxy colors: navy blue, purple, teal, and black.
10 - Place alternating spoonfuls of each colored buttercream onto the cake layers and sides. Use an offset spatula to swirl gently for a cosmic appearance.
11 - Sprinkle edible glitter generously over the cake. Add fondant zodiac symbols or stars if desired.
12 - Chill for 30 minutes before slicing to allow the design to set properly.

# Expert Advice:

01 -
  • The vanilla sponge is impossibly tender and actually stays moist for days, unlike some layer cakes that turn to cardboard by day two.
  • You get to play artist without needing actual artistic talent—swirling buttercream looks intentional no matter what happens.
  • Edible glitter transforms it from homemade cake into something that feels like it came from a fancy bakery, and people genuinely gasp when they see it.
02 -
  • If your buttercream looks grainy or broken while you're mixing, it means the butter was too cold or the temperature difference between ingredients was too extreme—gently warm the bowl over steam for 10 seconds and it'll come back together.
  • Edible glitter is your friend only if you sprinkle it on frosting that's set enough to hold it; on warm buttercream it sinks and disappears.
  • The three-pan approach bakes faster than doing two layers and doubling the frosting, but if you only have two pans, just bake in batches and let the pans cool between rounds.
03 -
  • Make the cake layers a day ahead and wrap them individually in plastic wrap—they actually taste better the next day as they settle, and you can focus entirely on frosting and decorating without stress.
  • If you're nervous about layering, freeze each frosted layer for 15 minutes before adding the next one; this prevents sliding and gives you more control.
  • Fondant Pisces symbols are pretty but totally optional—the swirled buttercream and glitter do all the heavy lifting.
