Preheat oven to 350 degrees F. In a large mixing bowl, mash bananas and stir in eggs, melted coconut oil, vanilla, and almond butter. Add the oat flour, baking soda, baking powder, and salt to bowl and mix well. Stir in the chocolate chunks or save to sprinkle on top of your muffins.
Pour into silicon muffin cups for muffins that fall right out! Fill roughly 2/3 to the top. Bake for 20 minutes and allow to cool. The cooling of these muffins is crucial to having them taste their best and slide out from their baking cups, easily. Enjoy!
