The best banana muffin recipes have a sweet crumb topping which is what makes these banana muffins stand apart from the ordinary. They're scrumptious!
1 ½ cups all-purpose flour
1 teaspoon baking soda
1 teaspoon baking powder
½ teaspoon salt
3 bananas, mashed
¾ cup white sugar
⅓ cup butter, melted
1 egg, lightly beaten
Crumb Topping:
⅓ cup packed brown sugar
2 tablespoons all-purpose flour
⅛ teaspoon ground cinnamon
1 tablespoon butter
Preheat the oven to 375 degrees F (190 degrees C). Lightly grease or line 10 muffin cups with paper liners.
Prepare muffins: Mix flour, baking soda, baking powder, and salt together in a large bowl.
Beat bananas, white sugar, melted butter, and egg together in a separate bowl; stir the banana mixture into the flour mixture just until combined. Spoon batter into prepared muffin cups, filling each about 3/4 full.
Prepare crumb topping: Mix brown sugar, flour, and cinnamon together in a small bowl. Use a fork to mix in 1 tablespoon butter until mixture is crumbly; sprinkle topping over muffins.
Bake in the preheated oven until a toothpick inserted into the center comes out clean, 18 to 20 minutes.
