Ingredients

• Cake: 2 ½ cups (310 g) all-purpose flour, 2 ½ tsp baking powder, ½ tsp salt, 1 cup (225 g) unsalted butter at room temperature, 1 ¾ cups (350 g) granulated sugar, 4 large eggs at room temperature, 1 tbsp pure vanilla extract, 1 cup (240 ml) whole milk at room temperature
• Buttercream Frosting: 1 ½ cups (340 g) unsalted butter at room temperature, 5 cups (600 g) powdered sugar sifted, 2 tsp pure vanilla extract, ¼ cup (60 ml) whole milk at room temperature, blue gel food coloring in various shades, white gel food coloring
• Decoration: Edible pearls or sugar pearls (optional), white chocolate or fondant for Pisces symbol (optional)

Instructions

Step 1: Prepare the pan

Preheat oven to 350°F (175°C). Grease and line a 9x13-inch (23x33 cm) sheet cake pan 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 butter and sugar until light and fluffy, about 3 minutes.

Step 4: Add eggs and vanilla

Add eggs one at a time, mixing well after each addition. Beat in vanilla extract.

Step 5: Combine wet and dry

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

Step 6: Bake

Pour batter into prepared pan and smooth the top. Bake for 28-32 minutes, or until a toothpick inserted in the center comes out clean.

Step 7: Cool

Cool cake in pan for 10 minutes, then transfer to a wire rack to cool completely.

Step 8: Make buttercream

Beat butter on medium speed until creamy, about 2 minutes. Gradually add powdered sugar, mixing on low. Add vanilla and milk; beat until fluffy and smooth.

Step 9: Color the buttercream

Divide buttercream into 3-4 bowls. Tint each with varying shades of blue (from deep ocean blue to pale aqua) and leave one portion white.

Step 10: Apply crumb coat

Once cake is completely cool, spread a thin layer of white buttercream over the entire cake as a crumb coat. Chill for 20 minutes.

Step 11: Create wave effect

With an offset spatula, layer blue buttercreams in wave-like shapes across the cake, starting with the darkest shade at the base and working up to the lightest. Use swooping motions to mimic ocean waves.

Step 12: Add sea foam

Pipe or swirl white buttercream on top to create sea foam.

Step 13: Final decoration

(Optional) Decorate with edible pearls and add a Pisces symbol made from white chocolate or fondant.

Zusatztipps für die Zubereitung

For the best results, ensure all your ingredients are at room temperature before you begin—this helps create a smooth, even batter that bakes uniformly. When making the buttercream, use gel food coloring rather than liquid varieties, as gels provide vibrant colors without thinning the frosting's consistency. The crumb coat is essential; don't skip this step as it creates a smooth foundation and prevents cake crumbs from mixing into your final decorative layer. Chill the cake between decorating steps for cleaner, more defined lines in your wave pattern. If you want to add extra flavor dimension, incorporate a teaspoon of lemon zest into the cake batter for a subtle citrus note that complements the vanilla beautifully.

Varianten und Anpassungen

This versatile recipe welcomes creative adaptations to suit different tastes and occasions. For a tropical twist, substitute coconut extract for half the vanilla and add shredded coconut to the batter. Chocolate lovers can create a chocolate ocean cake by replacing ½ cup of flour with cocoa powder. To make it dairy-free, use plant-based butter and your favorite non-dairy milk, ensuring both are at room temperature. For different zodiac signs, simply change the color palette—use purple and gold for Sagittarius, pink and red for Leo, or green and earth tones for Taurus. You can also experiment with different piping techniques: use star tips for more textured waves or petal tips for delicate, flowing designs. Add a layer of fruit preserves between the cake and frosting for extra moisture and flavor.
