Ingredients

• Cake: 2 ½ cups (315 g) all-purpose flour, 2 ½ tsp baking powder, ½ tsp baking soda, ½ tsp salt, 1 cup (225 g) unsalted butter (softened), 2 cups (400 g) granulated sugar, 4 large eggs (room temperature), 1 tbsp vanilla extract, 1 cup (240 ml) whole milk (room temperature), zest of 1 lemon
• Lemon Curd Filling: 4 large egg yolks, ½ cup (100 g) granulated sugar, ⅓ cup (80 ml) fresh lemon juice, zest of 2 lemons, ¼ cup (55 g) unsalted butter (cubed)
• Whipped Cream Frosting: 2 cups (480 ml) heavy cream (chilled), ½ cup (60 g) powdered sugar, 1 tsp vanilla extract
• Decoration (optional): Fresh berries (strawberries, raspberries, blueberries), edible flowers or lemon zest curls

Instructions

Step 1: Prepare the pan and dry ingredients

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

Step 2: Cream butter and sugar

In a large bowl, cream butter and sugar with an electric mixer until pale and fluffy, 3-4 minutes. Add eggs one at a time, beating well after each. Mix in vanilla and lemon zest.

Step 3: Combine wet and dry ingredients

Add the dry ingredients to the wet mixture in three parts, alternating with the milk. Begin and end with the dry ingredients. Mix until just combined.

Step 4: Bake the cake

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

Step 5: Make the lemon curd

While the cake cools, make the lemon curd: In a small saucepan, whisk together egg yolks, sugar, lemon juice, and zest. Cook over medium-low heat, stirring constantly, until thickened (about 5-7 minutes). Remove from heat and whisk in butter until smooth. Transfer to a bowl, cover surface with plastic wrap, and chill until cold.

Step 6: Prepare the frosting

For the frosting, whip cold heavy cream, powdered sugar, and vanilla until stiff peaks form. Keep refrigerated until ready to use.

Step 7: Assemble the cake

Once the cake is cool, carefully slice it horizontally to create two layers. Remove the top layer and spread the chilled lemon curd evenly over the bottom layer. Replace the top layer.

Step 8: Frost and decorate

Spread the whipped cream frosting evenly over the cake. Decorate with fresh berries, edible flowers, or lemon zest as desired.

Step 9: Chill before serving

Chill cake for at least 1 hour before serving for clean slices.

Zusatztipps für die Zubereitung

For easier slicing, use a serrated knife and chill the assembled cake well before cutting. If you're short on time, substitute store-bought lemon curd—just make sure to choose a high-quality brand for the best flavor. For extra lemon flavor, brush the cake layers with a simple lemon syrup before assembling. Use a pastry brush to apply the syrup evenly, allowing it to soak in for a few minutes before adding the curd. When making the lemon curd, constant stirring is essential to prevent curdling—low and slow is the key to silky perfection. Keep your whipped cream frosting in the refrigerator until the very last moment to maintain its structure and prevent it from becoming too soft.

Varianten und Anpassungen

This versatile sheet cake can be adapted to suit different tastes and occasions. Try using lime curd instead of lemon for a tropical twist, or add a layer of fresh raspberry preserves alongside the lemon curd for a tart-sweet combination. For a richer frosting, substitute half of the whipped cream with cream cheese beaten until fluffy before folding in the whipped cream. You can also add fresh berries between the layers for extra color and flavor. For a gluten-free version, use a 1:1 gluten-free flour blend, though the texture may be slightly different. To make individual portions, bake the batter in a muffin tin and create mini layered cakes—perfect for parties where guests can grab their own serving.

Serviervorschläge

This Spring Birthday Sheet Cake pairs beautifully with a glass of sparkling wine, champagne, or homemade lemonade for a refreshing complement to the citrus flavors. Serve each slice with a few extra fresh berries on the side and a sprig of mint for an elegant presentation. For an afternoon tea setting, cut the cake into smaller squares and arrange on a tiered stand alongside scones and finger sandwiches. The cake is best served chilled, which makes it particularly refreshing on warm spring days. If you're hosting a brunch, consider serving it alongside fresh fruit salad and coffee. The light, creamy texture also makes it an excellent choice for outdoor garden parties—just be sure to keep it refrigerated until serving time to maintain the frosting's stability.
