Method
Prep
- Preheat oven to 375°F and line a 12-cup muffin tin with paper liners. Arrange the tin on a sheet pan for easy transfer in and out of the oven.
Mix batter
- Whisk melted butter, sugar, egg, vanilla, and milk into mashed bananas until smooth. Keep mixing until no banana lumps remain.
Combine dry ingredients
- Fold in all-purpose flour, baking powder, baking soda, cinnamon, and salt until just combined. Stop mixing as soon as the flour disappears to keep the crumb tender.
Add chips
- Fold in 1 cup of semi-sweet chocolate chips. The batter should look thick and studded.
Fill and top
- Fill muffin cups about 3/4 full. Aim for even portions so the domes bake uniformly.
Press chips on top
- Press the remaining semi-sweet chocolate chips into the tops of each muffin. The chips should sit visibly on the surface for the glistening look.
Bake
- Bake for 18–22 minutes at 375°F until domed, golden, and a toothpick inserted in the batter area comes out clean. The tops should spring back lightly when touched.
Cool
- Cool in the tin for 5 minutes before transferring to a rack. Let them finish cooling until warm or room temperature for best texture.
Notes
Pro tip: Use very ripe bananas with visible brown spots for the richest flavor and naturally sweeter batter. Store muffins in an airtight container at room temperature for up to 2 days or in the refrigerator for up to 5 days; rewarm 10–15 seconds in the microwave if you like. Freeze baked muffins for up to 2 months. For a simple dietary swap, replace regular milk with unsweetened almond milk to keep the same bake time.
