White Chocolate & Mascarpone Mousse Cake

Mousse means 'foam' in French, and this cake stays true to its name. The sweetness of the white chocolate is tempered by the more neutral, creamy taste of the mascarpone, so the result is not cloying, but sophisticated. The air bubbles introduced into the cream with the whipped cream make the texture light, almost melting on the tongue.

Instructions

1

Prepare the base: crush the biscuits into fine crumbs, mix with the melted butter, and press into the bottom of the tin. Place in the fridge.

Tip: The finer the crumbs, the better the base holds together when cutting.
2

Melt the white chocolate over steam, then leave to cool until lukewarm. Mix the mascarpone until smooth with the sugar and vanilla.

Tip: The mascarpone should not be ice cold, otherwise the melted chocolate trickled into it would set immediately (the cream would have chocolate shards).
3

Bloom the gelatine in the water, heat until liquid. Stir into the melted chocolate, then work this mixture into the mascarpone.

Tip: This order ensures that the gelatine is distributed evenly in the thick cream.
4

Whip the double cream into medium peaks. Fold into the mascarpone base in several batches with gentle movements.

Tip: Do not mix too aggressively, or you will break the foam and the cake will be flat and dense.
5

Spread the cream over the biscuit base and refrigerate for at least 4 hours.

Tip: Leave on the counter for 30 minutes before serving so the chocolate flavour is more pronounced (cold dulls flavours).

Recipe FAQ

Can I use gelatine leaves instead of powder?
Yes, 10g powder corresponds to approx. 6 leaves. Soak in cold water, squeeze out, then dissolve in warm liquid.
How long does it keep?
2-3 days in the fridge, but best fresh (after setting), as the mousse texture can change over time.
