Ingredients

Why this recipe works

The combination of lemon and raspberry is a classic pairing that balances bright acidity with sweet berry notes. The lemon sponge is tender and moist, thanks to buttermilk, which adds a subtle tang and helps create a fine crumb.

The mascarpone cream is whipped with heavy cream and confectioners' sugar, resulting in a stable yet airy filling that holds its shape without being too heavy. The lemon curd adds a concentrated burst of citrus flavor, while fresh raspberries provide a pop of color and a slight tartness that cuts through the richness.

The white chocolate glaze is simple to make and sets to a shiny, elegant finish. Using a box grater to create lemon white chocolate curls adds texture and visual appeal without requiring special equipment. Chilling the cake before glazing ensures the cream is firm, so the glaze flows smoothly and doesn't cause the layers to slide. The result is a tall, impressive cake that slices cleanly and tastes as good as it looks. Each component can be prepared ahead, making this a practical choice for entertaining.

Notes and substitutions

For the sponge, use room-temperature eggs and buttermilk to ensure a smooth, even batter. Lemon zest adds essential oils that enhance the citrus flavor; avoid the white pith, which is bitter. If you don't have buttermilk, you can make a quick substitute by adding a tablespoon of lemon juice to a cup of milk and letting it sit for five minutes. The mascarpone cream should be whipped just until stiff peaks form; overbeating can cause it to become grainy.

Store-bought lemon curd works well and saves time, but make sure it's thick and not too runny. Fresh raspberries are best for both flavor and appearance; if using frozen, thaw and pat them dry to avoid excess moisture. For the glaze, use good-quality white chocolate that melts smoothly.

Lemon white chocolate adds an extra layer of citrus flavor, but regular white chocolate with a little lemon extract is a fine substitute. The cake is best assembled on the day you plan to serve it, though the components can be made ahead.

• lemon white chocolate: Use regular white chocolate and add 1/2 tsp lemon extract or zest to the glaze.
• mascarpone cheese: Substitute with an equal amount of full-fat cream cheese, softened, for a tangier cream.
• buttermilk: Mix 1 cup whole milk with 1 tbsp lemon juice and let sit for 5 minutes.
• fresh raspberries: Frozen raspberries can be used, but thaw and pat dry to avoid excess moisture.
