Banana-Chocolate Chip Muffins

1 1/2 cups all-purpose flour

1/3 cup sugar

1 1/2 teaspoons baking powder

1/4 teaspoon salt

1 cup mashed ripe bananas (about 2 large)

1 large egg

1/2 cup unsalted butter, melted

1/4 cup milk

1/4 cup sour cream

3/4 cup semisweet chocolate chips

Heat oven to 350°F.  Line twelve 1/3-cup muffin cups with foil muffin liners.

Mix flour, sugar, baking powder, and salt in a large bowl.  Mix mashed bananas, egg, melted butter, milk, and sour cream in a medium bowl.  Stir banana mixture into dry ingredients until just blended (do not over-mix).  Stir in chocolate chips.

Divide batter among prepared muffin cups, filling each about 3/4 full.  Bake muffins until tops are pale golden and tester inserted into center comes out with some melted chocolate attached but no crumbs, about 32 minutes.  Transfer muffins to rack and cool.

Makes 12 muffins.
