Method
Prep the oven and pan
- Preheat oven to 375°F and line a 12-cup muffin tin with paper liners, keeping liners snug in each cup for clean release.
Mix wet ingredients with bananas
- Whisk melted butter, sugar, egg, vanilla extract, and milk into mashed ripe bananas until smooth, with no streaks visible.
Combine dry ingredients
- Fold in all-purpose flour, baking powder, baking soda, cinnamon, and salt until just combined, stopping as soon as the flour disappears.
Add chocolate chips
- Fold in 1 cup semi-sweet chocolate chips, distributing them evenly so some chips remain visible in the batter.
Fill and top
- Fill muffin cups about 3/4 full and press remaining semi-sweet chocolate chips into the tops of each muffin so they stay on during baking.
Bake
- Bake for 18–22 minutes at 375°F until domed, golden, and a toothpick inserted in the batter area comes out clean.
Cool
- Cool in the tin for 5 minutes before transferring muffins to a rack, so the crumb sets without sticking.
Notes
For taller, bakery-domed muffins, keep the batter thick—mix only until just combined and avoid over-stirring after adding flour. Store at room temperature in an airtight container for up to 2 days or refrigerate up to 4 days; freeze up to 2 months (reheat briefly in a 350°F oven). If you want a dairy-free swap, use plant-based butter and any milk substitute in the same amount.
