Chocolate Cake

I do enjoy baking birthday cakes for my friends. I always ask them for their favourite flavours and prepare a perfect cake. And Martha's frosting - oh my, that was the most wonderful chocolate mixture I've ever eaten! Unfortunately, as it was a gift, there is no picture from the inside.

Recipe for a sponge cake comes from my favourite Polish website and the best chocolate frosting comes from my favourite cook, Martha Stewart.

8. Pour the dough into previously prepared sprinform, put in the oven and bake for 35-40 minutes, to the point of a dry toothpick.
9. After that time, take the sponge cake out from the oven and energetically throw on a kitchen surface ( :) ). Cool down,

Filling:

1. Mix all the ingredients of the filling (also alcohol, if desired). Divide into 2 equal bowls.
2. Using a knife, cut the sides of the sponge cake, open springform, put the sponge cake upside down to take out the baking paper. 
3. Using thread or a big knife, cut the sponge cake lengthwise, into 2 (or if possible 3) equal layers.

2. Put another layer of cake and repeat steps with filling.
3. Cover with the last piece of sponge cake.
4. If there is any excess of the filling, sticking out on the cake's sides, take it out.
