6: Sieve together 80 g flour, 15 g powdered cocoa and 4 g baking powder.
7: Tip these dry ingredients into the sugar and egg mixture, mix well, then add the melted butter and chocolate. Mix again.
8: Pour the mixture into a buttered tin or non-stick mould.
9: If you would like the top of the cake to open up during cooking (like in the photo), dip a soft spatula in a cup of neutral-flavoured oil (groundnut, for example) and mark a groove along the top of the cake.
10: You can also make little individual cakes.
11: Bake for about 40 minutes, turn out and leave to cool on a wire rack.
12: If you have opted for small cakes, the cooking time will be much shorter.
13: Look at the lovely split along the top of this cake, the result of "slashing" the top just before it went in the oven.
Remarks
Once the cake batter is made, it can be kept cold until needed. The best way to do this is to pour it into its tin or mould and refrigerate. You can enrich this cake with lots of other ingredients: dried fruit, toasted nuts, apples or pears - let your imagination lead the way!
