Strawberry Pink Velvet White Chocolate Mousse Cake

A slice of this cake shows off everything at once: pink velvet sponge, a cloud of white chocolate mousse and bright strawberries in every layer. It looks like a bakery centerpiece, yet it comes together with a box grater, a bowl and a little patience in the fridge. Cut into it and you will see clean, firm layers that hold their shape on the plate.

This strawberry pink velvet white chocolate mousse cake is built like a layer cake with a fruit-and-mousse filling. Sliced strawberries and airy white chocolate mousse are stacked between pink velvet cake layers, chilled until set, and finished with a smooth pink strawberry glaze.

Fresh strawberries, whole and halved, sit on top with white chocolate curls grated from a block of white chocolate. The result is pretty and generous, and it suits birthdays, bridal showers and spring dinners. Most of the work happens in the refrigerator, so the cake gives you a relaxed finish. Plan the time for chilling, because the mousse needs hours to become firm enough to slice cleanly.

Ingredients

Why this recipe works

The mousse sets through two processes working together. Melted white chocolate firms as it cools, and the whipped cream traps air that keeps the mousse light.

Folding the chocolate into the cream in two additions prevents deflation and keeps the texture silky rather than dense. When the chocolate is only warm, it blends smoothly without seizing or leaving streaks, which is why the temperature matters so much at this stage.

Chilling is the step that turns a soft assembly into a sliceable cake. The fats in the chocolate and cream solidify slowly in the cold, locking the strawberry slices and cake layers in place. A long rest also lets the moisture from the strawberries settle into the mousse rather than pooling at the bottom. Glazing only after the cake has set keeps the pink coating sharp and prevents the mousse from sliding.

Notes and substitutions

Pink velvet cake layers can be bought ready-made or baked ahead, which saves an evening of work. Choose layers of equal thickness so the stack stays level.

Fresh strawberries give the best flavor and color, but firm, ripe berries will hold their shape better than very soft ones. Whipping cream should be chilled and labeled with at least 35 percent fat, since lower-fat cream will not hold the mousse structure.

A 9-inch springform pan makes unmolding easy, while a clear glass ring mold shows off the layers from the side, which is part of the appeal of this cake. A box grater is the fastest way to create fine shavings and curls for decoration.

A long serrated knife, warmed in hot water and wiped dry between cuts, gives neat slices. If you need a substitute for the strawberry glaze, a strained, warmed strawberry jam works well for a glossy finish.

• heavy cream: chilled whipping cream with at least 35 percent fat, whipped to the same soft peaks
• strawberry glaze: strawberry jam warmed with a spoonful of water and strained until smooth
• confectioners' sugar: superfine sugar dissolved in a spoonful of the cream before whipping
