Preheat the oven to 350 F
Mix the bananas, avocado, vanilla, and egg (flax egg for vegan option) in your food processor, or blender.
In a separate bowl, whisk together the spelt, cocoa, sweetener, baking soda, cinnamon, salt, and chopped up chocolate chunks. (vegan chocolate for vegan option)
Pour the dry ingredients into your food processor with the wet ingredients and mix until incorporated.
Spray a 9x5 bread pan and pour your mixture in. If you want a smooth top, use a spatula to smooth it out. Otherwise it will bake as is.
Bake for 40 minutes for a nice moist bread. If you want it a little drier, bake for an additional 5-10 minutes. Just keep checking it until you get the desired consistency!
Store in an airtight container in the refrigerator. Enjoy!
