Ingredients Method Notes

Ingredients

100 g ground almonds
80 g milk chocolate
2 teaspoons ground ginger
350 g chocolate for mousse
400 ml double cream
10 g chocolate same brand as mousse
60 ml water
1 teaspoon instant coffee
15 g cocoa powder
35 g golden caster sugar unrefined
8-10 ripe strawberries
100 g hazelnuts
Cocoa powder for dusting

Method

Begin by preparing the base layer, which forms the foundation of this elegant dessert. Gently melt 80 g of milk chocolate and stir in 2 teaspoons of ground ginger, then mix in 100 g of ground almonds.
Once the mixture has cooled slightly and is no longer too hot to handle, place a cake ring on your serving dish and gently press the chocolate mixture into it to create an even base. Refrigerate the base while you prepare the mousse component.
To make the mousse, chop 350 g of chocolate into small pieces and place in a bowl. Heat 150 ml of the 400 ml double cream in a small saucepan until it boils, then pour it over the chopped chocolate and stir until the chocolate has completely melted and the mixture is smooth.
Lightly whip the remaining double cream—being careful not to overwhisk, as this can make the mousse grainy—then fold it into the cooled chocolate cream mixture. Pour this mousse into the cake ring on top of the base, cover with cling film, and refrigerate for at least one hour.
While the mousse sets, prepare the glaze by chopping up 10 g of chocolate and setting it aside. In a small pan, bring 60 ml of water, 1 teaspoon of instant coffee, and 15 g of cocoa powder to a boil while whisking to dissolve the cocoa. In a separate pan over medium heat, melt 35 g of golden caster sugar until it becomes a golden caramel, brushing the pan with cold water as needed to prevent burning. Pour the water, coffee, and cocoa mixture into the caramel, then beat in the chopped chocolate until completely melted. Pass the glaze through a fine sieve, and once it has cooled but remains liquid, pour it over the mousse and return the cake to the refrigerator to set. The cake can be prepared overnight at this stage.

Chocolate Mousse Cake Substitutions And Variations

Once you’ve mastered the classic version, you’ll probably start wondering how to bend the rules a little, and honestly, that’s where the fun begins. I’d swap the ground almonds for crushed hazelnuts in the base—they’ll give you that same texture but with richer flavor. Want to go darker. Use 70% chocolate instead of milk chocolate for the mousse. It’s more intense, but totally worth it. For the strawberries, I’d consider raspberries or blackberries if that’s what I’m craving. They’re tartier, which balances the sweetness perfectly. You could also experiment with the glaze by adding a splash of orange liqueur or swapping the instant coffee for espresso powder. The hazelnuts on top work great, but I’d personally try crushed pistachios or toasted almonds for something different. Don’t be afraid to play around—that’s how you discover your signature version.
