Instructions

1. Preheat the oven to 350°F (175°C). Grease and line three 8-inch (20 cm) round cake pans with parchment paper.
2. In a large bowl, cream together the butter and sugar until light and fluffy. Add eggs one at a time, beating well after each addition. Mix in vanilla extract.
3. In a separate bowl, whisk together flour, baking powder, and salt.
4. Add the dry ingredients to the wet mixture in three parts, alternating with the milk, beginning and ending with the flour. Mix until just combined.
5. Divide the batter evenly among the prepared pans. Bake for 30–35 minutes or until a toothpick inserted in the center comes out clean.
6. Cool cakes in pans for 10 minutes, then transfer to wire racks to cool completely.
7. For the buttercream: Beat the butter until creamy. Gradually add powdered sugar, then milk and vanilla. Beat until fluffy.
8. Divide buttercream into four or five bowls. Tint each with a different galaxy color (black, navy blue, purple, pink, teal) using gel food coloring.
9. Place random spoonfuls of each color onto a large piece of plastic wrap. Roll up to form a log. Snip one end and transfer the log to a piping bag fitted with a large round tip.
10. Place one cake layer on a serving plate. Spread a thin layer of galaxy buttercream. Repeat with remaining layers.
11. Apply a generous crumb coat all over the cake. Chill for 20 minutes.
12. Pipe and spread the galaxy buttercream over the cake, swirling gently with an offset spatula to create a marbled galaxy effect.
13. Use white gel food coloring and a food-safe paintbrush or splatter tool to flick on stars across the cake surface.
