I am a mass killer of bananas; so I invented chocolate coconut banana coffee cake.  I feel so guilty about wasting over ripe bananas. I over buy and we under consume bananas on a regular basis. As a result I am always looking for ideas to use them up. I make quite a bit of traditional banana bread but it gets boring. I play with new banana baked goodies all the time, and this one I really like.

Dark Chocolate is a must

In this house all baked goods are required to contain at least some amount of chocolate. My husband has a server dark chocolate addiction. When I was rummaging around I found we had three things for this coffee cake: dark chocolate, coconut and bananas so I decided to mix it up and see. I was not disappointed.

Dark Chocolate Coconut Banana Coffee Cake

I used the dark chocolate cocoa powder so the coffee cake was extremely rich and looked almost black. I am sure chocolate coconut banana coffee cake would be just as tasty with normal cocoa powder, but my husband would never approve of such a thing. The added coconut gives just a hint of Mounds candy bar type flavor that is good with the banana. Don’t skip the walnut streusel, it is so good. I was picking the streusel crumbs off the plate every time I cut a slice of coffee cake. I baked this recipe in a 9×9 pan and got a coffee cake kind of thing but I think it would be great as chocolate coconut banana muffins too.
