These quick and easy banana muffins are soft, buttery, and spiced with cinnamon. Perfect for using up ripe bananas, they’re kid-friendly and can be made in under 30 minutes!
Preheat oven to 425°F (218°C). Line a 12-count muffin pan with liners or spray with nonstick spray. Set aside.
Whisk flour, baking soda, salt, cinnamon, and nutmeg together in a medium bowl. Set aside.
In a large bowl, mash the bananas. Whisk in the melted butter, brown sugar, egg, vanilla, and milk.
Add the dry ingredients to the wet ingredients and stir just until combined. Fold in walnuts or chocolate chips, if using.
Spoon the batter into the muffin cups, filling them all the way to the top.
Bake for 5 minutes at 425°F (218°C), then reduce the oven temperature to 350°F (177°C) and continue baking for 16–18 minutes until a toothpick comes out clean.
Allow muffins to cool for 5 minutes in the pan, then transfer to a wire rack to continue cooling.
Notes
You can use frozen bananas—thaw and drain any excess liquid before mashing. Whole wheat flour may be used for a healthier version.
