Ingredients

• For the Cake: 2 ½ cups (310 g) all-purpose flour, 2 cups (400 g) granulated sugar, 1 cup (240 ml) whole milk (room temperature), 1 cup (225 g) unsalted butter (softened), 4 large eggs (room temperature), 2 ½ tsp baking powder, ½ tsp salt, 1 tbsp vanilla extract
• For the Galaxy Buttercream: 1 ½ cups (340 g) unsalted butter (softened), 5 cups (600 g) powdered sugar (sifted), ¼ cup (60 ml) whole milk, 2 tsp vanilla extract, Gel food coloring in black, navy blue, purple, pink, and teal
• For Decoration: Edible gold and silver star sprinkles, Edible glitter or luster dust, White gel food coloring (for stars and swirls)

Instructions

Step 1: Prepare the pans

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

Step 2: Mix the wet ingredients

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.

Step 3: Combine dry ingredients

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

Step 4: Create the batter

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.

Step 5: Bake the cakes

Divide the batter evenly among the prepared pans. Bake for 30–35 minutes or until a toothpick inserted in the center comes out clean.

Step 6: Cool completely

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

Step 7: Make the buttercream

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

Step 8: Create galaxy colors

Divide buttercream into four or five bowls. Tint each with a different galaxy color (black, navy blue, purple, pink, teal) using gel food coloring.

Step 9: Prepare the piping bag

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.

Step 10: Assemble the layers

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

Step 11: Apply crumb coat

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

Step 12: Create the galaxy effect

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

Step 13: Add painted stars

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

Step 14: Final decoration

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

Step 15: Optional finishing touch

Optional: Add a graduation cap cake topper for a festive touch.

Zusatztipps für die Zubereitung

For the best galaxy buttercream effect, use high-quality gel food coloring rather than liquid food coloring—gel colors are more vibrant and won't thin out your buttercream. When creating the marbled galaxy effect in step 12, use a light hand with your offset spatula; over-mixing will muddy the colors instead of creating distinct swirls. Make sure all your ingredients, especially the butter, eggs, and milk, are at room temperature before beginning—this ensures a smooth batter and fluffy buttercream. The crumb coat in step 11 is essential for a professional finish, so don't skip the 20-minute chill time. If you're adding a layer of raspberry or blueberry jam between the cake layers for extra flavor, spread it thinly to avoid the layers sliding.

Varianten und Anpassungen

Customize your Galaxy Graduation Cake to match school colors by adjusting the gel food coloring palette—try combinations like red and gold, green and white, or blue and yellow. For a chocolate version, replace ½ cup of flour with unsweetened cocoa powder and add an extra 2 tablespoons of milk to the batter. If you prefer a smaller cake, divide the recipe in half and use two 6-inch pans instead of three 8-inch pans. For a gluten-free version, substitute the all-purpose flour with a 1:1 gluten-free baking flour blend. You can also experiment with different flavored extracts in the cake—almond or lemon extract adds a unique twist. For an adult celebration, brush each cake layer with a tablespoon of flavored liqueur before frosting.

Serviervorschläge

Serve this Galaxy Graduation Cake as the grand finale of your celebration meal, pairing it with sparkling wine, champagne, or a fruity punch for toasting the graduate. For a complete dessert spread, accompany the cake with fresh berries and whipped cream on the side. The cake looks stunning on a white or black cake stand that allows the galaxy colors to pop. Cut generous slices to serve 12 people, or smaller portions for up to 16 guests if serving alongside other desserts. This cake is rich and sweet, so consider serving it with hot coffee or cold milk to balance the flavors. Present the cake with sparklers or candles for an extra celebratory moment when bringing it to the table.
