Ingredients
Method
1.Brush a 22cm round cake tin with a little melted butter, line base with a disc of baking paper and brush that with butter, too, then dust tin with caster sugar. Preheat oven to 180°C.
2.Put cubed butter in a bowl and beat with an electric beater until creamy and loose. Gradually beat in sugar and continue beating until fluffy and lighter in colour (creamed) – you’ll need to stop the machine and scrape down the bowl several times. Beat eggs together with a fork, then add them gradually to the creamed mixture.
3.Mix in the ground and chopped almonds, chocolate, vanilla and lemon zest. Turn mixture into prepared tin and bake for 35-40 minutes, until the cake springs back when lightly pressed with a finger and is pulling away from the sides of the tin.
4.Cool in tin for 12-15 minutes, then turn out onto a cake rack lined with baking paper. Cool for 30 minutes, removing baking paper disc if attached. Cover with a clean piece of baking paper and a second rack. Flip cake over and remove top rack and paper.
5.When the cake is cool, sift with plenty of icing sugar and cut into slices for serving.
