Preheat your oven to 350°F (175°C) and grease a muffin tin or line it with paper liners.

In a large bowl, mash the ripe bananas until smooth.

In another bowl, combine rolled oats, flour, baking powder, and brown sugar.

Add eggs and milk to the mashed bananas, stirring until well combined.

Gradually mix the dry ingredients into the wet mixture until just combined; avoid overmixing.

Fold in chocolate chips gently.

Scoop batter into muffin cups and bake for 18-20 minutes or until golden brown.
