This celestial layer cake combines the comforting familiarity of classic vanilla cake with the artistic flair of galaxy-inspired decoration. The key to achieving that cosmic swirl lies in the buttercream technique—dividing your frosting into multiple bowls and tinting each with deep, jewel-toned gel colors before artfully swirling them together. The result is a cake that looks like it was pulled straight from the night sky, complete with nebula-like patterns and star-dusted shimmer.

Ingredients

• For the Vanilla Sponge: 2 ½ cups (315 g) all-purpose flour, 2 ½ tsp baking powder, ½ tsp salt, 1 cup (225 g) unsalted butter (room temperature), 2 cups (400 g) granulated sugar, 4 large eggs (room temperature), 1 tbsp pure vanilla extract, 1 cup (240 ml) whole milk (room temperature)
• For the Galaxy Buttercream: 1 ½ cups (340 g) unsalted butter (room temperature), 5 cups (600 g) powdered sugar (sifted), ¼ cup (60 ml) whole milk, 2 tsp vanilla extract, gel food coloring (navy blue, purple, black, teal), edible glitter (silver, blue, or iridescent)
• For Decoration: White fondant (optional, for Pisces symbols or stars), silver star sprinkles (optional)

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 Dry Ingredients

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

Step 3: Cream Butter and Sugar

In a large bowl, cream the butter and sugar until light and fluffy, about 3-4 minutes.

Step 4: Add Eggs and Vanilla

Add eggs one at a time, beating well after each addition. Mix in vanilla extract.

Step 5: Combine Wet and Dry

Alternate adding the flour mixture and milk to the butter mixture, beginning and ending with flour. Mix until just combined.

Step 6: Bake the Cakes

Divide the batter evenly among the prepared pans. Bake for 25–30 minutes, or until a toothpick inserted into the center comes out clean.

Step 7: Cool Completely

Cool cakes in pans for 10 minutes, then turn out onto a wire rack to cool completely.

Step 8: Make the Buttercream

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

Step 9: Create Galaxy Colors

Divide buttercream into four bowls. Tint each with different galaxy colors (navy, purple, teal, black).

Step 10: Apply Galaxy Effect

Place alternating spoonfuls of each colored buttercream onto the cake layers and sides. Use a spatula to swirl gently for a galaxy effect.

Step 11: Add Sparkle

Sprinkle edible glitter generously over the cake. Add fondant Pisces symbols or stars if desired.

Step 12: Set the Design

Chill for 30 minutes before slicing to set the design.

Zusatztipps für die Zubereitung

For the best results, ensure all your ingredients are at room temperature before you begin—this helps create a smoother batter and prevents curdling. When creating the galaxy effect, don't over-swirl the colors; a light touch preserves the distinct color bands that give the cosmic appearance. For extra shimmer, brush a little clear alcohol like vodka over the cake before sprinkling glitter—the alcohol evaporates quickly and helps the glitter adhere beautifully. Use an offset spatula for smoother frosting application and more controlled swirling patterns.

Varianten und Anpassungen

This versatile recipe welcomes creative adaptations to suit different tastes and dietary needs. Substitute almond extract for vanilla to add a subtle nutty flavor twist that pairs beautifully with the buttery cake. For gluten-sensitive guests, use a high-quality gluten-free flour blend in place of all-purpose flour—the texture remains wonderfully tender. You can also experiment with different color schemes: try pink and gold for a romantic take, or silver and white for a winter wonderland version. Add a layer of raspberry or lemon curd between the cake layers for an extra burst of flavor.

Serviervorschläge

This celestial showstopper deserves an equally magical presentation. Serve at room temperature on a pristine white cake stand to let the cosmic colors truly shine. The cake pairs beautifully with sparkling Moscato or champagne for adult celebrations, or a refreshing homemade lemonade for all-ages gatherings. Consider serving alongside fresh berries or a light vanilla bean ice cream to complement the rich buttercream. For themed parties, arrange the cake on a dark tablecloth scattered with star confetti and battery-operated fairy lights to enhance the celestial atmosphere.
