  • Cake: 2 1/2 cups (315 g) all-purpose flour, 2 1/2 tsp baking powder, 1/2 tsp salt, 1 cup (225 g) unsalted butter (softened), 1 3/4 cups (350 g) granulated sugar, 4 large eggs (room temperature), 2 tsp vanilla extract, 1 cup (240 ml) whole milk (room temperature)
  • Ocean Galaxy Buttercream: 1 1/2 cups (340 g) unsalted butter (softened), 6 cups (720 g) powdered sugar (sifted), 1/4 cup (60 ml) whole milk, 2 tsp vanilla extract, gel food coloring in navy blue, teal, purple, turquoise, and white, edible glitter or white sprinkles for stars

Instructions

Step 1: Prepare the pans
Preheat oven to 350°F (175°C). Grease and line two 8-inch (20 cm) round cake pans with parchment paper.
Step 2: Mix dry ingredients
In a medium bowl, whisk together flour, baking powder, and salt.
Step 3: Cream butter and sugar
In a large bowl, beat the butter and sugar with an electric mixer until light and fluffy, about 3-4 minutes.
Step 4: Add eggs and vanilla
Add eggs one at a time, mixing well after each. Mix in vanilla extract.
Step 5: Combine wet and dry
Alternately add the dry ingredients and milk to the butter mixture, starting and ending with flour. Mix until just combined.
Step 6: Bake the cakes
Divide batter evenly between prepared pans. Smooth tops and bake for 28-32 minutes, or until a toothpick inserted in the center comes out clean.
Step 7: Cool completely
Cool cakes in pans for 10 minutes, then turn out onto wire racks to cool completely.
Step 8: Make buttercream base
For the buttercream, beat softened butter until creamy. Gradually add powdered sugar, beating well. Add vanilla and milk; beat until smooth and fluffy (about 3-4 minutes).
Step 9: Color the buttercream
Divide buttercream into 4 or 5 bowls. Tint each portion with gel food coloring to create navy, teal, purple, turquoise, and leave one white.
Step 10: Create galaxy effect
Place random dollops of each colored buttercream onto the cake (crumb-coated first, if desired). Use an offset spatula to swirl colors together for a marbled galaxy effect.
Step 11: Add starry details
Decorate with edible glitter or white sprinkles for a starry look.
Step 12: Chill before serving
Chill the cake for at least 30 minutes before slicing for clean layers.

Zusatztipps für die Zubereitung

For the best results, ensure all your ingredients—especially butter, eggs, and milk—are at room temperature before you begin. This helps create a smooth, evenly textured batter. When creating the galaxy effect, work quickly but deliberately; use an offset spatula to swirl the colors in long, sweeping motions rather than over-mixing, which can muddy the distinct hues. A crumb coat (thin first layer of buttercream) will help keep cake crumbs from mixing into your beautiful galaxy colors. The cake can be made a day in advance and refrigerated, making party preparation easier.

Varianten und Anpassungen

For extra flair, add sugar sea shells or Pisces zodiac toppers to enhance the astrological theme. Substitute almond or coconut extract for part of the vanilla for a subtle flavor twist that complements the ocean theme. You can adjust the color palette to match different ocean moods—try silvery blues and seafoam greens for a lighter, tropical vibe, or deep indigos and violets for a mysterious deep-sea effect. For a gluten-free version, use a 1:1 gluten-free baking flour blend. Add a hint of lemon zest to the cake batter for a bright, refreshing note.

Serviervorschläge

This stunning cake deserves a equally beautiful presentation. Serve on a white or silver cake stand to make the ocean galaxy colors pop. Surround the base with scattered edible pearls, sugar crystals, or small seashells for an underwater tablescape. Pair each slice with a scoop of vanilla bean ice cream or a dollop of whipped cream. For beverages, consider serving with sparkling water infused with lavender or butterfly pea flower tea, which mirrors the mystical blue-purple hues of the cake. The cake cuts beautifully after chilling, revealing clean layers that showcase your artistic buttercream work.
