Tiramisu Mousse Cake

Tiramisu ('pick me up') is a modern classic from Veneto. While the original is a spoon dessert, this cake version is sliceable thanks to gelatin, without losing its famous creaminess. Layers of coffee-soaked ladyfingers and rich mascarpone cream create a perfect balance of texture and flavor.

Instructions

1

Whisk egg yolks and sugar over a double boiler until warm (approx. 160°F) and pale yellow. Remove from heat.

Tip: This creates a 'sabayon' base and makes the eggs safe to eat.
2

Dissolve the bloomed gelatin in the warm egg mixture. Let it cool to lukewarm.

Tip: Gelatin ensures the cake cuts cleanly.
3

Loosen the mascarpone with a spatula (do not use an electric mixer!), then fold in the egg mixture.

Tip: Machine mixing can cause mascarpone to curdle.
4

Whip heavy cream to soft peaks and gently fold into the mascarpone base.

Tip: Soft peaks blend easier without lumps.
5

Line the springform pan. Briefly dip ladyfingers in coffee and line the bottom.

Tip: Dip for just 1 second; they act like sponges and will get soggy if soaked too long.
6

Spread half the cream over the base, add another layer of dipped ladyfingers, and top with remaining cream. Chill for 4 hours.

Tip: Flavors need time to meld.
7

Dust generously with cocoa powder just before serving.

Tip: Cocoa absorbs moisture, so fresh dusting looks best.

Recipe FAQ
