# How To Make:

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, beat the butter and sugar with an electric mixer until light and fluffy, approximately 3-4 minutes.
04 - Add eggs one at a time, beating well after each addition. Mix in vanilla extract until fully combined.
05 - Alternately add the flour mixture and milk to the butter mixture, starting and ending with flour. Mix until just combined to avoid overmixing.
06 - Divide batter evenly among the prepared pans. Bake for 25-30 minutes until a toothpick inserted into the center comes out clean.
07 - Cool cakes in pans for 10 minutes, then invert onto a wire rack 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 portion 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 galaxy effect.
11 - Sprinkle edible glitter generously over the cake. Add fondant Pisces symbols or stars if desired.
12 - Chill for 30 minutes before slicing to set the design.

# Expert Tips:

01 -
  • The vanilla sponge is tender enough to melt on your tongue but sturdy enough to hold three layers without collapsing under the weight of all that gorgeous buttercream.
  • Edible glitter transforms an ordinary cake into something Instagram-worthy, but honestly, the real magic is watching someone's face light up when they see it in person.
  • This cake actually gets better after a few hours in the fridge because the flavors settle and the buttercream sets into this silky, dreamlike texture.
02 -
  • Buttercream that looks separated or broken usually just needs more beating—don't throw it away, keep mixing and it'll come together silkily.
  • If your cake layers are doming too much on top, let them cool completely, then slice off the domes with a serrated knife to create level, stackable layers.
  • Edible glitter sticks best to buttercream when it's still slightly soft, so don't wait too long after frosting to add that shimmer.
03 -
  • Room temperature ingredients are non-negotiable—set your eggs and butter out an hour before you start baking and you'll notice a profound difference in how smoothly everything comes together.
  • If you want to make this cake a day ahead, bake the layers, cool them completely, wrap them tightly in plastic wrap, and store them at room temperature; frost the cake the day you're serving it for the freshest taste.
