Prep and mix
- Preheat the oven to 375°F and line a 12-cup muffin tin with paper liners, so the batter can go in right away.
- Whisk melted butter, sugar, egg, vanilla, and milk into the mashed bananas until smooth, using a uniform mixture for a moist crumb.
- Fold in all-purpose flour, baking powder, baking soda, cinnamon, and salt until just combined, then fold in any mix-ins until you no longer see dry flour.
Bake
- Divide batter evenly among the muffin cups, filling each about 3/4 full for tall, domed muffins.
- Sprinkle sugar on top of each muffin for a crunch if desired, and you should see a light dusting before baking.
- Bake for 18–22 minutes at 375°F until domed, golden, and a toothpick comes out clean.
Notes
For the best domed shape, avoid overmixing after the flour goes in—stop as soon as the batter looks combined. Store muffins in an airtight container at room temperature for up to 3 days, or refrigerate up to 5 days; freeze up to 2 months (thaw overnight). For a lighter option, swap half the all-purpose flour for whole wheat flour for a slightly nuttier crumb.
