# 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.
03 - In a large bowl, cream together butter and sugar until light and fluffy, approximately 3 to 4 minutes.
04 - Add eggs one at a time, beating well after each addition. Mix in vanilla extract until fully incorporated.
05 - Alternate adding the flour mixture and milk to the butter mixture, beginning and ending with flour. Mix until just combined to avoid overmixing.
06 - Divide batter evenly among the three prepared pans. Bake for 25 to 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 a wire rack to cool completely.
08 - Beat butter until creamy. Gradually add powdered sugar, milk, and vanilla extract; beat until smooth and fluffy.
09 - Divide buttercream into four separate 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, creating a galaxy effect.
11 - Sprinkle edible glitter generously over the entire cake. Add fondant Pisces symbols or stars if desired.
12 - Chill for 30 minutes before slicing to set the design and allow colors to fully blend.

# Expert Advice:

01 -
  • The vanilla sponge is impossibly moist and forgiving, which means even your first attempt will feel like a triumph.
  • Swirling buttercream in galaxy colors hides imperfections beautifully, so your cake will look intentionally artistic rather than wonky.
  • Edible glitter transforms a regular cake into a showstopper that makes people gasp before they even taste it.
02 -
  • Gel food coloring is non-negotiable here; liquid coloring will thin your buttercream so much that your beautiful swirls will slide right off the sides of the cake.
  • Room temperature ingredients aren't just a suggestion—they're the difference between a silky batter and one that looks curdled and separates, which compromises your cake's texture entirely.
03 -
  • Use an offset spatula for frosting and swirling; it gives you so much more control than a regular butter knife and makes the whole process feel less intimidating.
  • If your buttercream is too soft and won't hold swirls, pop it in the fridge for 10 minutes to firm up slightly, which changes everything about the final appearance.
