# How-To:
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 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 combined.
05 - Alternately add flour mixture and milk to butter mixture, beginning and ending with flour. Mix until just combined, avoiding overmixing.
06 - Divide batter evenly among prepared pans. Bake for 25 to 30 minutes, or until a toothpick inserted in 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 extract. 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 colored buttercream onto cake layers and sides. Use an offset spatula to create gentle swirls for a galaxy effect.
11 - Sprinkle edible glitter generously over the cake. Add fondant Pisces symbols or stars if desired.
12 - Chill cake for 30 minutes before slicing to set the design.
