This is such a simple bread that can be a snack, dessert or breakfast. The recipe is the one I used when making the Vegan Banana Muffins but I added some cocoa powder.
When you have all the ingredients combined....separate the batter in half into two bowls. To one bowl, add about 3 tbs of cocoa powder and stir until it's all combined in the batter. Then, in your bread pan, pour the regular batter in first, then the chocolate batter and swirl it around with a knife.
