# Cooking 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 until evenly distributed.
03 - In a large bowl, cream together butter and sugar for 3-4 minutes until light and fluffy, scraping down bowl sides as needed.
04 - Add eggs one at a time, beating well after each addition. Mix in vanilla extract until fully 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 25-30 minutes until a toothpick inserted in center comes out clean.
07 - Cool cakes in pans for 10 minutes, then invert 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 portion with different gel food colors: navy blue, purple, teal, and black.
10 - Place alternating spoonfuls of each colored buttercream onto cake layers and sides. Use an offset spatula to swirl gently for galaxy effect.
11 - Sprinkle edible glitter generously over frosted cake. Add fondant Pisces symbols or stars if desired.
12 - Refrigerate for 30 minutes to set the frosting and glitter design before slicing.
