Instructions

1. Preheat the oven

Preheat the oven to 350°F (175°C). Grease and line three 8-inch (20 cm) round cake pans with parchment paper.

2. Cream butter and sugar

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. Mix dry ingredients

In a separate bowl, whisk together flour, baking powder, and salt.

4. Combine wet and dry

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. Bake

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

Cool cakes in pans for 10 minutes, then transfer to wire racks to cool completely.

7. Prepare buttercream

Beat the butter until creamy. Gradually add powdered sugar, then milk and vanilla. Beat until fluffy.

8. Color buttercream

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. Prepare piping log

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. Assemble cake layers

Place one cake layer on a serving plate. Spread a thin layer of galaxy buttercream. Repeat with remaining layers.

11. Crumb coat

Apply a generous crumb coat all over the cake. Chill for 20 minutes.

12. Decorate cake

Pipe and spread the galaxy buttercream over the cake, swirling gently with an offset spatula to create a marbled galaxy effect.

13. Flick stars

Use white gel food coloring and a food-safe paintbrush or splatter tool to flick on stars across the cake surface.

14. Add final decoration

Decorate with edible gold and silver star sprinkles and a sprinkle of edible glitter or luster dust.

15. Optional topper

Add a graduation cap cake topper for a festive touch.

Zusatztipps für die Zubereitung

For even more delicious flavor, consider adding a layer of raspberry or blueberry jam between the cake layers. Make sure to use high-quality gel food coloring for the most vibrant and beautiful galaxy colors. Use an offset spatula gently to keep the marbled effect smooth and elegant.
