First of all we have to mix butter and sugar with the mixer.
After mixing, add eggs and sprig vanilla to it.
Mix it again with the mixer till it becomes soft.
Now in another bowl, add flour and baking powder.
Mix it and add this dry flour mixture to the butter mixture slowly slowly so that it does not get messy.
Now when the mixture gets mix very welll then blend it with the mixer for two to three mins.
Now the batter is ready, so divide it into two portions.
In one portion, add sifted cocoa powder and blend it very well.
Now grease the loaf pan and pre heat the oven for 10 mins.
On the other hand, pour half of the vanilla batter into the loaf pan.
Then pour half of the chocolate batter over the vanilla batter.
Now again pour vanilla batter then layer of chocolate batter.
Now with the knife, cut into the batter in different patterns to give the marble effect.
After cutting, place this loaf pan in pre heated oven for 50 mins.
When it is done, check with the knife.
If it comes out clean, it means it is done.
Demould it when it cools down.
Then cut it into slices.
This can be enjoyed at evening tea time.
