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 and dry ingredients

Preheat oven to 350°F (175°C). Grease and line a 9x13-inch (23x33 cm) sheet cake pan with parchment paper. In a medium bowl, whisk together flour, baking powder, and salt.

Step 2: Cream butter and sugar

In a large bowl, beat butter and sugar until light and fluffy, about 3 minutes.

Step 3: Add eggs and vanilla

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

Step 4: Combine wet and dry ingredients

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

Step 5: Bake the cake

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 6: Cool completely

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

Step 7: Make the 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 8: 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 9: 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 10: Create ocean waves

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 11: Add sea foam details

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

Step 12: Final decorations

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

Zusatztipps für die Zubereitung

To ensure your ocean wave cake turns out flawlessly, always bring all ingredients to room temperature before starting—this creates a smoother batter and more stable buttercream. When coloring your frosting, use gel food coloring rather than liquid to maintain the proper consistency and achieve vibrant hues without thinning the buttercream. Chill the cake between decorating steps for cleaner lines and easier handling. For the most dramatic wave effect, use an offset spatula with confident swooping motions, working from dark to light shades. If you're adding lemon zest to the sponge for extra flavor, fold it in gently at the end to preserve the cake's tender texture. Always sift your powdered sugar to prevent lumps in your buttercream, ensuring a silky-smooth finish.

Varianten und Anpassungen

This versatile sheet cake welcomes creative adaptations to suit different tastes and occasions. For a citrus twist, add 1-2 tablespoons of lemon zest to the cake batter and substitute lemon extract for half the vanilla. Create a chocolate version by replacing ½ cup of flour with cocoa powder and using chocolate buttercream as the base layer. For a tropical ocean theme, add coconut extract to the frosting and sprinkle toasted coconut over the waves. You can also experiment with different color schemes—try purple and pink ombré for a sunset ocean, or green and teal for a mermaid-inspired look. For those avoiding dairy, substitute plant-based butter and milk alternatives, though the texture may vary slightly. Add a layer of fruit preserves between the cake and frosting for extra moisture and flavor dimension.

Serviervorschläge

Present this stunning Pisces cake as the centerpiece of your dessert table, allowing its artistic waves to take center stage. Serve each slice with a dollop of freshly whipped cream or a scoop of vanilla bean ice cream to complement the sweet buttercream. For an elegant pairing, offer a glass of sparkling water with a twist of lemon, light Moscato, or champagne to enhance the celebratory atmosphere. The cake pairs beautifully with fresh berries—particularly blueberries and raspberries—which echo the ocean color palette. For a themed presentation, arrange slices on white or aqua plates with a dusting of edible pearl dust or a drizzle of white chocolate. This cake is ideal for birthday parties, zodiac celebrations, baby showers with nautical themes, or any gathering where you want to make a memorable impression with both flavor and visual artistry.
