Chocolate sponge cake

Ingredients:

3/4 cup maida/ all purpose flour
2 tblsp cocoa powder
120 gms unsalted butter
3/4 cup powdered sugar
2 eggs
1 tblsp baking powder
1 tblsp vanilla essence
2 tblsp tutti frooti or chopped walnuts (optional)

Method:
1)Mix Maida, cocoa powder and baking powder in a container.
2) Melt the butter. Add powdered sugar and beaten eggs. Beat this mixture well till you get a nice creamy mixture.(You can use electric beater to do the same or use a mixer/blender)
3) Add vanilla essence to the egg mixture.
4) Mix this to the dry mixture of maida, cocoa and baking powder. You can add tooti frooti or chopped walnuts during this stage.
5) Rub some butter over the baking container and sprinkle some maida over it. Tap the container to remove the excess flour.
6) Pour the mixture in the container and bake it in electric oven or gas oven.
7) I used gas oven here. Keep the gas on slow flame and let it bake for 20 mins.
8) To check whether the cake is baked properly insert a tooth pick in the middle of the cake. It should come out clean.
9) The cake is ready.
