Chocolate Banana Marble Bread

Banana bread has to be one of the most popular and well-loved snacks around. I have shared a few recipes on this site for various types of banana bread but I have to say, this one may be my fave yet. Who wouldn't love rich chocolate and banana batter swirled together into one incredible loaf?

Though this loaf doesn't rise as high as the other banana breads I have made in the past, I was amazed at its fine crumb and velvety texture. This baby is far from dense or dry. It is heavenly sliced up plain or smeared with some cream cheese. Personally I love mine with butter while it is still warm from the oven.

2 things about this recipe you should be aware of: 1. SIFT your dry ingredients. Do not skip this step. You want velvety then you must sift. 2. Use high quality cocoa powder. The cocoa powder is the only form of chocolate in this recipe so don't go cheap.

This bread is made in a large loaf pan and is ready in about 50-55 minutes. The batter, divided into light and dark, is swirled together right before baking. Though I did find the prep time a bit longer and more complex than your standard banana bread recipe, the pay off is big. I swear to you, make this once and you will never look back.

So if you are ready for some knock your socks off Chocolate Banana Marble Bread then let's get at it !
