Preheat the oven to 350 F.

Mix all the dry ingredients in a bowl. Mix wet ingredients in a separate bowl. Fold wet into dry mixture.

Pour half or slightly lesser portion of the batter in a bowl and add the cocoa powder. Mix well to form a dark brown batter.

Pour the plain batter into a greased loaf pan. Now pour the brown batter onto it. Using a knife or skewer, swirl the two batters together. Since the batters are on the thicker side, the swirls may not form perfectly.

Bake for 30-35 minutes or until a skewer/ knife stuck into the bread comes out clean. Allow it to cool for a few minutes before removing onto a plate. Slice, serve and enjoy.
