I found some recipees for marble cake on the web. After filtering out the ones with ingredients not available (or difficult to organize) here in india I settled for the following recipee. I reduced the amount of maida since I don’t want a granite cake and replaced butter with margarine:
- 250g margarine
- 250g sugar
- 5 eggs
- 1.5dl milk
- 400g maida (fine flour)
- 2 teaspoons baking powder
- 1 teaspoon vanilla essence
- 3 teaspoons cocoa powder
Mix all ingredients except vanilla and cocoa. Then take one third away and mix it with the cocoa powder. Mix the rest with the vanilla essence. Put alternate layers of white and dark dough into a cake pan. Gently stir it with the handle of a spoon to make the pattern look more random.
Bake 40-60 minutes at 180°C, rectangle pan might need longer (check with knitting needle).
The result is a nice strong cake (not falling apart when holding a piece), not too sweet.
