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

1. Preheat your oven to 350°F (175°C). Grease and line a 9x13-inch (23x33 cm) sheet pan with parchment paper.

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

3. 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.

4. 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.

5. 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.

6. 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.

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

8. 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.

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

10. 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. This ensures the layers hold together and the slices remain neat when served.

Varianten und Anpassungen

Substitute store-bought lemon curd to save time without compromising on flavor. For extra lemon intensity, brush the cake layers with lemon syrup before assembling.

Serviervorschläge

Pairs beautifully with a glass of sparkling wine or refreshing lemonade, making it an ideal centerpiece for spring celebrations.
