Dead good chocolate cake recipe - Recipes - BBC Good Food

Heat the oven to 160C/fan 140C/gas 3. Butter and line a 20cm cake tin. Using an electric whisk, beat together butter and light muscovado sugar in a large bowl until fluffy. Measure out plain flour and self-raising flour. Beat in 5 eggs one at a time, adding 1 or 2 tbsp flour if the mixture starts to split. Pour 300g melted and slightly cooled dark chocolate into the mixture, beating as you do so. Fold in the rest of the flour. Spoon into the tin and bake for 1 hour 30 minutes; the cake should be risen with a crust on top. Cool and then take out of the tin. Split the cake horizontally.

To make the icing, gently melt together dark chocolate with double cream. Cool until thickened slightly. Fill the cake with icing, then spread the rest over the outside.
