I always buy bananas when I go to the grocery store. I usually put them in smoothies, but sometimes I buy more than I can use and they start turning brown on me. Anyone who’s ever bought bananas knows that once they’re brown, you better use them because the next day they’ll be mushy and super sweet.

Sometimes I can get them in the freezer before that happens, but sometimes life gets in the way, and I’ll have a few that can’t be saved. Luckily, while they may not be able to be used in smoothies (at least not for me; too sweet), they still have some uses, one of which is this banana cake.

Chopped Chocolate

This cake is moist and flavorful, but it’s not super sweet. The addition of high quality dark chocolate compliments the sweetness of overripe bananas nicely.  Coconut oil and lemon zest add a zing, and  plain or vanilla yogurt adds richness and moisture. You can bake this in a bread pan like traditional banana bread if that’s more your thing.

Plain Yogurt

Banana Cake One of the best things about this cake is that like most quick breads, it will keep for several days and still be as moist as when you first baked it.
