Ingredients

2 cups all-purpose flour 

2 1/4 teaspoons baking powder 

1 teaspoon coarse salt 

1/4 teaspoon ground cinnamon 

3 extra-ripe bananas, mashed (1 cup) 

3/4 cup light brown sugar 

1 stick unsalted butter, melted 

1 large egg 

1/4 cup milk 

1 cup semi-sweet chocolate chips 

Preparation

Preheat oven to 350 degrees. Line a standard 12-cup muffin tin with baking cups. In a medium bowl, whisk together flour, baking powder, salt, and cinnamon. In a separate bowl, whisk together banana, sugar, egg, butter, and milk. Stir wet ingredients into dry ingredients then stir in chocolate chips.

Divide batter evenly between prepared cups, adding a scant 1/4 cup to each. Bake until tops spring back when lightly touched, about 20 minutes. Cool in pans 5 minutes, then remove to wire rack to cool completely.
