Method
Preheat and prep
- Preheat oven to 375°F and line a 12-cup muffin tin with paper liners.
Make the batter
- Whisk melted butter, sugar, egg, vanilla, and milk into mashed bananas until smooth.
- Fold in all-purpose flour, baking powder, baking soda, cinnamon, and salt until just combined.
- Fold in 1 cup of semi-sweet chocolate chips.
Fill and top
- Fill muffin cups about 3/4 full.
- Press remaining semi-sweet chocolate chips into the tops of each muffin.
Bake and cool
- Bake for 18–22 minutes until domed, golden, and a toothpick inserted in the batter area comes out clean.
- Cool in tin for 5 minutes before transferring muffins to a rack.
Notes
For the bakery-domed look, avoid overmixing—once the flour disappears, stop folding so the crumb stays moist. Store in an airtight container at room temperature for 2 days or refrigerate up to 4 days. Freeze up to 2 months (thaw overnight, then warm 10–15 minutes in a 300°F oven). For a lighter option, use unsalted butter and swap milk for low-fat milk without changing bake time.
