CHOCOLATE MOUSSE CAKE

Steps:

• heat oven to 160C/fan 140/gas 3. Line and butter a 23cm springform tin. Put chocolate and butter in a pan and melt over a very low heat. Set aside. Using an electric whisk, beat the eggs with the sugar for about 5mins untill the mixture is thick, pale and doubled in volume.
• Pour the chocolate into the whisked egg mixture, then gently, but thoroughly, fold in. Add the broken biscuits, then gently fold again.
• Pour the mixture into the prepared tin, then bake for 40-45mins until just firm. Remove from the oven and allow to cool in the tin for about 1/2-3/4 hr. You can serve it while still warm and the centre is still melty and gooey, as in the picture, or you can chill it (up to a day ahead) and it will be firm and fudgy enough to cut into wedges. Serve with double cream and fresh blueberries or homemade ice cream.
