Preheat oven to 350 degrees.  In a blender or food processor combine mashed bananas, eggs, nut butter and ghee.  Blend for 10 seconds or until combined.

Add in coconut flour, almond flour, cacao powder, baking soda, baking powder, vanilla and salt. Blend again until completely combined.

Add in chocolate chunks and pulse once or twice just to incorporate.

Pour into a greased 8 x 4 inch loaf pan and top with a few extra chocolate chunks.

Bake for 45 minutes or until a toothpick inserted comes out with just few crumbles.
