Raspberry Lemon Curd Mascarpone Layer Cake Tips, FAQ & printable recipe

Tips for success

For the most stable mascarpone cream, ensure the mascarpone is cold, not softened, and beat it with the cream and sugar until just combined before adding the lemon juice. Overbeating can cause the mixture to break.

To create beautiful white chocolate curls, use a block of chocolate and a box grater, pressing firmly and evenly. Chill the chocolate for a few minutes if it starts to soften. When glazing, pour the glaze over the center and use an offset spatula to gently push it to the edges, letting it drip naturally for an organic look.

To achieve clean slices, use a long, sharp knife and wipe it between cuts. Dip the knife in hot water and dry it before each slice for the neatest edges. If the cake is too soft, chill it for an additional 30 minutes before slicing.

For a more intense lemon flavor, add a little lemon extract to the mascarpone cream or the glaze. The cake is best served slightly chilled, allowing the flavors to meld while the cream retains its structure.

Variations

• Berry Medley: Swap the raspberries for a mix of fresh blueberries, blackberries, and sliced strawberries. Adjust the amount of lemon curd to taste, as berries vary in sweetness.
• Lemon Blueberry: Use fresh blueberries instead of raspberries for a sweeter, less tart filling. Blueberries pair beautifully with lemon and white chocolate.
• Citrus Twist: Replace the lemon curd with orange curd and use orange zest in the sponge. Garnish with candied orange peel instead of lemon wheels.
• Dark Chocolate Drizzle: Instead of white chocolate glaze, drizzle melted dark chocolate over the top. The bitterness of dark chocolate contrasts nicely with the sweet mascarpone cream.

Storage and make-ahead

Fridge

Store in the refrigerator for up to 3 days, covered. Let stand at room temperature for 15 minutes before serving.

Freezer

Freeze unfrosted sponge layers for up to 2 months. Assemble and glaze after thawing.

Reheat

Not recommended; serve chilled or at room temperature.

Store the assembled cake in the refrigerator, covered loosely with plastic wrap or in a cake carrier, for up to 3 days. The cream and glaze will keep the cake moist.

Before serving, let it sit at room temperature for about 15 minutes to take the chill off, but do not leave it out for more than 2 hours. The raspberries may release some juice over time, so add them fresh if you plan to store the cake for more than a day.

The lemon sponge layers can be baked up to 2 days ahead, wrapped tightly in plastic wrap, and stored at room temperature. The mascarpone cream can be made a day ahead and refrigerated in an airtight container; give it a quick whisk before using.

The white chocolate glaze can be prepared up to 3 days ahead and reheated gently. The assembled cake can be made a day ahead and kept refrigerated, but add the fresh raspberry garnish just before serving for the best appearance.

Serving ideas

Serve the cake chilled or at room temperature, cut into thick wedges. A metal cake server is ideal for lifting the tall slices without disturbing the layers. Pair each slice with a dollop of extra mascarpone cream or a spoonful of lemon curd if desired, though the cake is rich enough on its own. The bright citrus and creamy texture make it a delightful finish to a spring or summer meal.

For a special presentation, arrange additional fresh raspberries and lemon wheels on the serving platter around the cake. A dusting of confectioners' sugar or a few mint leaves can add a touch of color, but keep it simple to let the cake shine. This cake is perfect for birthdays, bridal showers, or any celebration where a showstopping dessert is needed.

Raspberry Lemon Curd Mascarpone Layer Cake

Prep 40 minCook 30 minRest 30 minTotal 1 h 40 minServes 12

Ingredients

• 2 1/4 cups all-purpose flour
• 2 1/2 tsp baking powder
• 1/2 tsp salt
• 3/4 cup unsalted butter, softened
• 1 1/2 cups granulated sugar
• 3 large eggs
• 1 tsp vanilla extract
• 1 cup buttermilk
• 2 tbsp lemon zest
• 1 1/2 cups lemon curd (store-bought or homemade)
• 2 cups mascarpone cheese
• 1 cup heavy cream
• 1/2 cup confectioners' sugar
• 2 tbsp lemon juice
• 2 cups fresh raspberries
• 8 oz white chocolate, finely chopped
• 1/2 cup heavy cream
• 2 oz lemon white chocolate, grated into curls
• 1 lemon, sliced into thin wheels

Instructions

1. Heat the oven to 350°F (175°C). Grease and flour two 9-inch round cake pans. In a medium bowl, whisk together the flour, baking powder, and salt. In a large bowl, beat the butter and sugar until light and fluffy, about 3 minutes. Add the eggs one at a time, beating well after each addition, then beat in the vanilla and lemon zest. With the mixer on low, add the flour mixture in three additions, alternating with the buttermilk, beginning and ending with the flour.
2. Bake for 25 to 30 minutes, until a toothpick inserted in the center comes out clean and the cakes spring back when lightly pressed. Let the cakes cool in the pans for 10 minutes, then turn them out onto a wire rack to cool completely. The internal temperature of the cakes should read 160°F (71°C) when done.
3. In a large chilled bowl, beat the mascarpone, heavy cream, confectioners' sugar, and lemon juice together until stiff peaks form. Be careful not to overbeat, as the mixture can curdle. The cream should be thick and spreadable.
4. Place one cake layer on a serving plate. Spread a generous layer of lemon curd over the top, then a layer of mascarpone cream. Scatter fresh raspberries over the cream, pressing them in slightly. Place the second cake layer on top and spread the remaining mascarpone cream over the top and sides of the cake.
5. Refrigerate the assembled cake for at least 30 minutes to firm up the cream before adding the glaze. This helps the glaze flow smoothly and prevents the cake from sliding.
6. Place the chopped white chocolate in a heatproof bowl. Heat the heavy cream in a small saucepan until just simmering, then pour it over the chocolate. Let sit for 2 minutes, then stir until smooth and glossy. Let the glaze cool slightly until it thickens to a pourable consistency.
7. Pour the white chocolate glaze over the top of the chilled cake, letting it drip down the sides. Use an offset spatula to spread it evenly, if needed. Immediately garnish with fresh raspberries, grated lemon white chocolate curls, and lemon wheels.
8. Refrigerate the cake for at least 1 hour to set the glaze. To serve, slice a thick triangular wedge and lift it with a metal cake server. The layers should be distinct and the cream set.
