Use those overripe bananas to make a batch of these mini banana muffins! These little muffins are easy to make and can be packaged up for quick weekday breakfasts or after-school snacks. Make them your own by adding your favorite mix-ins, such as mini chocolate chips or chopped nuts.
Preheat oven to 350°F. Spray a mini muffin pan with nonstick cooking spray or line with mini paper muffin liners.
In a large bowl, whisk together the flour, baking soda, salt and cinnamon. Set aside.
2 ¼ cups all-purpose flour, 1 ½ teaspoons baking soda, ½ teaspoon kosher salt, 1 teaspoon ground cinnamon
In the bowl of a stand mixer fitted with the paddle attachment, or in a large bowl with an electric mixer, beat the brown sugar and butter on medium speed until light and fluffy; about 3 minutes.
Add in the egg, mixing until incorporated. Add in the bananas, sour cream and vanilla and mix until fully combined.
1 large egg, 3 very ripe bananas, 8 ounces sour cream, 1 teaspoon pure vanilla extract
With the mixer on low, gradually add in the flour mixture and mix until just combined.
Use a medium cookie scoop (1 ½ tablespoons) to divide the batter amongst the mini muffin wells.
Bake in the preheated oven for 14-16 minutes, or until a toothpick inserted in the center of a muffin comes out clean.
Cool mini muffins in the pan for about 5 minutes before removing them to a wire rack to cool completely.
Repeat with remaining batter as needed.
Notes
Store in an airtight container at room temperature for up to 3 days or in the refrigerator for up to 5 days. Freeze for up to 3 months. Feel free to add your favorite mix-ins, such as mini chocolate chips or finely chopped nuts, before dividing the batter into the muffin tins.
