Cacao Mousse Cake

Ingredients

· 180g cacao, finely grated
· 250g unsalted butter
· 5 eggs
· 200g golden caster sugar
· 1 tsp vanilla extract

Directions

1. Preheat the oven to 160°C (fan). Line a 25cm cake tin with non-stick baking paper.

2. Melt the cacao and butter by placing them in a large heatproof bowl set over a pan of simmering water.

3. Meanwhile, beat the eggs with the sugar and the vanilla extract until pale yellow and fluffy.

4. Pour the cacao mixture into the eggs and beat to combine.

5. Stand the lined tin in a roasting tray and fill the tin with the mousse mixture.

6. Pour enough boiling hot water into the roasting tray to come halfway up the side of the tin. Bake for 30 minutes or until set. Leave to cool in the tin.
