# Put the butter which was softened in the room temperature into a deep bowl, add castor
sugar on it. Blend this mixture for a while.
# Add the eggs into the mixture. Add the
milk after mixing it for a while.
# Add the sifted
flour, salt, baking powder and vanilla into the mixture, get a smooth mixture. (This mixture must be harder than the other cake mixtures.) Put away half of the mixture, add
cocoa into the remaining part of the mixture, and mix.
# Grease the cake mould well. Put 1 tbsp mixture with
cocoa into the mould, and then place 1 tbsp
cocoa free mixture beside. Make a layer on the floor of the cake mould by repeating this act.
# Place white mixture on the black ones, and black mixture on the white ones for the second layer.
# You can make more layers for using up all the mixture by the same method.
# Place the cake mould into the 329 F oven which is preheated a little before. Baking takes about 1 hour. (For understanding if it gets cooked or not, you should dip a tooth pick in the cake. If it does not get cooked, the dough sticks around the pick.)
# Rest the baked cake in the oven at first and then out of the oven.
# Reverse it onto a flat service plate and slice.
