Preheat the oven to 375°F (190°C) or preheat an air fryer to 360°F (180°C). Lightly grease a mini muffin pan.
Blend the cottage cheese until completely smooth for the best texture.
Add the eggs, mashed banana, and vanilla extract, then blend again until the mixture is smooth and well combined.
Stir in the oat flour or almond flour, baking powder, salt, and chocolate chips until everything is just combined.
Spoon the batter into the prepared mini muffin pan and bake for 12–15 minutes, until the bites are puffed and set.
