Preheat your oven to 350°F. Line a mini muffin pan with liners or grease it lightly.
In a mixing bowl, mash the bananas until smooth.
Stir in the applesauce, maple syrup, milk, and vanilla until combined.
Sift in the cocoa powder, then add oat flour, baking soda, and salt. Mix just until no dry spots remain.
Fold in the mini chocolate chips. Try not to eat too many straight from the bag (I failed).
Spoon the batter evenly into the muffin pan, filling each about 3/4 full.
Bake for 10–12 minutes or until a toothpick inserted comes out with a few moist crumbs.
Let cool for a few minutes before popping them out and sneaking a warm one. Or two.
