Instructions
- Prepare Pans and Oven: Preheat the oven to 165°C / 325°F. Line three 15 cm (6-inch) cake pans with parchment paper to prevent sticking and ensure even baking.
- Mix Dry Ingredients: In a bowl, sift together the all-purpose flour, cornstarch, baking powder, baking soda, and fine salt to evenly distribute the leavening agents and remove any lumps.
- Cream Butter and Sugar: In a large bowl, beat the softened butter with powdered sugar and lemon zest for 2–3 minutes until the mixture is creamy and light, which helps incorporate air for a fluffy cake texture.
- Add Wet Ingredients: Add the eggs and vanilla extract to the butter-sugar mixture, beating again for 3–5 minutes until smooth and fully combined.
- Combine Batter: Alternately fold in the dry ingredients and the buttermilk mixed with lemon juice using a spatula, being careful not to overmix to keep the batter light and tender.
- Bake Cake Layers: Divide the batter evenly among the prepared pans and bake for about 30 minutes, or until the tops are golden and a skewer inserted in the center comes out clean.
- Cool Cakes: Allow the cakes to cool briefly in the pans before unmolding. Then cool completely on a wire rack to room temperature to prepare for layering.
- Make Strawberry Compote: Combine strawberries, granulated sugar, and lemon juice in a saucepan and cook over medium heat for 12–15 minutes, stirring occasionally, until strawberries are softened yet slightly chunky.
- Cool Compote: Let the compote cool completely, then transfer it to a jar and refrigerate until needed to enhance flavor and consistency.
- Prepare Strawberry Purée: Before assembling the cake, blend 100 g of the chilled compote into a smooth purée to be used in the buttercream for intense strawberry flavor.
- Make Swiss Meringue Buttercream: Heat the egg whites and granulated sugar over a double boiler while whisking constantly until sugar dissolves and the temperature reaches 160°F (71°C) to ensure safety and stability.
- Whip Meringue: Transfer the egg white mixture to a stand mixer and whip until stiff, glossy peaks form and the mixture is completely cool to the touch, creating a stable meringue base.
- Add Butter: Gradually add the softened cubed butter to the meringue while mixing, beating until the buttercream is smooth and thick.
- Incorporate Strawberry Purée: Mix in the strawberry purée and vanilla extract gently just until combined. Optionally, add red gel food coloring for a vibrant color.
- Smooth Buttercream: Switch to the paddle attachment and mix on low speed for 1–2 minutes to achieve a smooth and consistent buttercream texture.
- Make Lemon Mascarpone Cream: In a bowl, combine cold mascarpone, heavy cream, lemon curd, powdered sugar, and vanilla extract and whip on low to medium speed for about 2 minutes until smooth and firm.
- Level Cake Layers: Trim the tops of the cake layers if necessary to create flat and even surfaces for stacking.
- Assemble Cake Layers: Place the first cake layer on a cake board, pipe a border of strawberry buttercream around the edge to contain filling, then spread a layer of strawberry compote followed by lemon mascarpone cream inside the border.
- Stack Remaining Layers: Repeat the filling process with the remaining layers of cake, compote, and lemon mascarpone cream, stacking them carefully to maintain stability.
- Crumb Coat: Apply a thin crumb coat of strawberry buttercream over the entire cake to seal in crumbs, then chill the cake for at least 2 hours (or 30 minutes in the freezer) to set the coating.
- Final Frosting Layer: After chilling, frost the cake with a thicker layer of strawberry buttercream and smooth the surface with a spatula or icing scraper for a polished finish.
- Make White Chocolate Lemon Drip: Melt white chocolate and heavy cream together over a double boiler until smooth, then stir in lemon curd and yellow gel food coloring (optional) for a glossy, flavorful drip.
- Apply Drip: Let the drip mixture cool to about 30°C (86°F), then carefully drip it over the chilled cake to create an elegant drip effect.
- Decorate: Use piped strawberry buttercream and fresh lemon slices to decorate the top of the cake, adding visual appeal and extra flavor.
- Serve: Remove the cake from the refrigerator 20–30 minutes before serving to allow flavors and texture to soften slightly for the best eating experience.
Notes
- Ensure all eggs and dairy are at room temperature before starting for best mixing and texture.
- Use fresh or frozen strawberries for the compote; thaw frozen strawberries before cooking.
- Be gentle when folding the batter to maintain its airiness and tenderness.
- Chilling the cake after the crumb coat is essential to achieve a smooth final frosting.
- The cake can be stored covered in the refrigerator for up to 3 days; bring to room temperature before serving.
- If desired, you can add more lemon zest inside the cake layers for an extra citrus punch.
- Use gel food coloring sparingly to avoid altering the taste or texture of the buttercream.
