Frosted Chocolate Chunk Banana Zucchini Cake Recipe

Frosted Chocolate Chunk Banana Zucchini Cake

How are we feeling about all the summer zucchini recipes these days? Tired of the stuff already? What if I made up a banana zucchini cake recipe, added big chunks of dark chocolate to it and topped it with the fluffiest chocolate frosting ever? Yes? Thought so.

This cake… this is what happens when the zucchinis are growing like wildfire and there are a couple of sad bananas on the counter (I mean that little situation just screams cake to me, but maybe that’s a bit of a problem…). This zucchini cake is so easy to make, is loaded with chocolate and is slathered with the very best fluffy chocolate frosting. Heaven.
