This is a recipe from The Minimalist Baker...but I tweaked it and it's not bad at all.
If you want the vegan gluten free version, head on over there...this uses just plain flour, olive oil, and regular oats...not the organic kind
3 ripe bananas
3 teaspoons baking powder
pinch of salt
1/3 cup crunchy peanut butter
3 tablespoons oil (olive oil, coconut oil-whatever you prefer)
1/2 cup raw sugar
3/4 cup almond milk (or whatever milk you prefer)
1 1/4 cup almond meal
1/2 cup cocoa powder
1 cup plain flour
1 cup oats
1/4 cup chocolate chips
Preheat the oven to 180 deg and grease and line a loaf pan with baking paper
Beat the egg and add the banana and mash through, then add the other ingredients down to the almond milk and mix to combine well.
Add the cocoa powder, almond meal, flour and oats and stir, then stir in the chocolate chips
Pour into the prepared loaf pan and bake for about an hour...it should feel firm to the touch and a little cracked on top
Let cool completely before cutting.
