Raspberry Lemon Curd Mascarpone Cream Layer Cake: A Showstopper Tips, FAQ & printable recipe

Tips for success

For perfectly clean slices, use a long, thin-bladed knife dipped in hot water and wiped dry before each cut. This will help the knife glide through the cream and glaze without dragging.

Chill the cake for at least 30 minutes before slicing to make it easier to cut neat wedges. If the cake is too cold, let it sit at room temperature for 10 minutes before serving to allow the flavors to come forward.

When grating the chocolate, use a light touch and let the curls fall onto a parchment-lined sheet. If the chocolate starts to melt, return it to the refrigerator for a few minutes.

To make the lemon wheels, slice the lemons as thinly as possible, ideally with a mandoline. Pat them dry before placing on the cake to prevent excess moisture from making the glaze run.

Variations

• Berry Medley: Replace the raspberries with a mix of fresh blueberries, blackberries, and sliced strawberries. The combination of berries adds a variety of flavors and colors, making the cake even more vibrant.
• Lemon Blueberry: Swap the raspberries for fresh blueberries and add a teaspoon of lemon zest to the mascarpone cream. The blueberries pair beautifully with the lemon curd, offering a different but equally delicious berry note.
• Citrus Twist: Use a combination of lemon and orange curd for the filling, and garnish with candied orange peel instead of lemon wheels. The orange adds a sweet, aromatic depth that complements the lemon.
• Chocolate Lover's: Replace the white chocolate glaze with a dark chocolate ganache and use dark chocolate curls for decoration. The bitterness of dark chocolate contrasts nicely with the sweet cream and tart raspberries.

Storage and make-ahead

Fridge

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

Freezer

Unfrosted cake layers can be frozen for up to 2 months. Once assembled, the cake is best not frozen as the texture may suffer.

Reheat

This cake is best served cold or at room temperature. Do not reheat.

Store leftover cake in an airtight container in the refrigerator for up to 3 days. The cake is best enjoyed within 24 hours of assembly, as the raspberries may release moisture over time. Let the cake sit at room temperature for 15-20 minutes before serving to soften the cream and enhance the flavors.

The sponge cake can be baked a day ahead and stored wrapped in plastic wrap. The lemon curd and white chocolate glaze can be made up to 3 days in advance and refrigerated.

The mascarpone cream can be whipped a few hours ahead and kept chilled. Assemble the cake on the day of serving for the freshest presentation.

Serving ideas

Serve this cake as the grand finale to a special meal. A slice with a cup of black tea or coffee is a delightful pairing.

The bright citrus and berry flavors make it a lovely spring or summer dessert, but it's welcome any time of year. For an extra touch, dust the plate with powdered sugar or add a small sprig of mint.

This cake is rich and satisfying, so a modest slice is plenty. Cut the cake into 12 equal wedges for a generous serving. If serving at a party, you can cut thinner slices to feed more people. The cake's stunning appearance makes it a centerpiece on any dessert table.

Raspberry Lemon Curd Mascarpone Cream Layer Cake: A Showstopper

Prep 45 minCook 30 minRest 30 minTotal 1 h 45 minServes 12

Ingredients

• 1 9-inch yellow sponge cake layer, store-bought or made ahead
• 3 lemons, thinly sliced into wheels
• 2 cups fresh raspberries, cleaned
• 6 oz lemon white coverture chocolate, grated into curls
• 1 cup mascarpone cheese, softened
• 1 cup heavy cream, cold
• 1/2 cup confectioners' sugar, sifted
• 2 tbsp fresh lemon juice
• 1 cup glossy yellow lemon curd, store-bought or homemade
• 1 cup white chocolate lemon glaze, warm

Instructions

1. Slice the lemons into thin wheels and set aside. Clean the raspberries by gently rinsing and patting dry. Grate the lemon white chocolate on a box grater into a pile of curls. If the cake layer is not already level, trim the top with a serrated knife to create an even surface.
2. In a stand mixer fitted with the whisk attachment, beat the mascarpone, heavy cream, confectioners' sugar, and lemon juice on medium speed until stiff peaks form. Be careful not to overbeat, or the cream will curdle.
3. Using a serrated knife, carefully slice the sponge cake layer horizontally into two even layers. Place one layer on a serving plate or cake board.
4. Spread a generous layer of the mascarpone cream over the bottom cake layer. Dollop the lemon curd over the cream and gently spread it into an even layer, leaving a small border. Scatter a handful of fresh raspberries over the curd.
5. Place the second cake layer on top, cut side down. Press gently to adhere. Spread a thin crumb coat of mascarpone cream over the entire cake to seal in crumbs. Refrigerate for 30 minutes to set.
6. Spread the remaining mascarpone cream over the top and sides of the cake. Use a bench scraper or offset spatula to create smooth, even sides. Chill for another 15 minutes.
7. Pour the warm white chocolate lemon glaze over the top of the cake, letting it drip down the sides. Use an offset spatula to spread it evenly if needed.
8. Arrange the lemon wheels and remaining raspberries on top of the cake. Sprinkle generously with the grated white chocolate curls. Slice a thick triangular wedge and lift it with a metal cake server to serve.
