Place rack in the center of the oven and preheat to 350 degrees. Line a muffin tin with 12 paper liners.
Combine flour, sugar, baking powder, baking soda and salt into a large mixing bowl and then mix in lightly beaten eggs, milk, vanilla and melted butter just until combined.
Fold in lightly mashed bananas and chocolate chips until well combined.
Scoop batter into muffin liners, filling each one fully.
Bake 20 minutes or until a toothpick in the center comes out just about clean. Allow muffins to rest for 5 minutes in the pan, then transfer to a rack to cool completely. Enjoy!
Notes
Don’t leave the muffins to cool in the pan otherwise the trapped steam will make the bottoms too sticky!
