In a bowl, mash peeled bananas with a fork or with a Kitchenaid paddle
Mix in the butter,oil, vanilla, and sugar
In a separate bowl mix the dry ingredients together; flour, cocoa, salt, and baking soda
Mix ⅓ of the dry ingredients with the wet, scraping down the bowl before adding another scoop of the flour mixture.
Stir in chocolate chips and nuts (optional)
Grease 1 large loaf pan or 2 smaller pans (batter should fill ¾ to top)
Bake 350F until a toothpick comes out clean (just make sure you don’t hit a choc chip) 1 large loaf should take 55 -60 minutes and 2 smaller loaves will take aproximately 35-40 minutes. Once mine get close, I just shut the oven off and leave the loaves in oven for aproximately another 10 min, loaves always come out perfectly moist!
