Chestnut Mousse Cake

Here, chestnut dominates the cream rather than the batter. The density of chestnut paste is lightened by whipped cream, creating a mousse-like, airy texture. The sponge is merely a vehicle; the star is the creamy topping.

Instructions

1

Make the base sponge: cream butter and sugar, add eggs, then flour, baking powder, and salt. Bake at 350°F (180°C) for 20-25 minutes. Cool.

Tip: Basic butter cake method.
2

For the cream, mash the chestnut puree and mix with half the liquid heavy cream (to thin it out), then fold in whipped cream made from the remaining half.

Tip: This makes it easier to blend without lumps.
3

Dissolve gelatin in a little warm water and temper it into the cream. Spread over the cake.

Tip: Chestnut is dense, so gelatin helps it slice cleanly.
4

Chill for 3 hours, then garnish with grated chocolate.

Tip: Chocolate and chestnut are a classic pair.

Recipe FAQ

Sweetened or unsweetened chestnut?
Most recipes assume sweetened chestnut puree (crème de marrons). If using unsweetened puree, add extra powdered sugar and a drop of rum extract!
