Step 1

Preheat the oven to 375 degrees Fahrenheit (190°C) and spray the top of the muffin pan with cooking spray. Add muffin liners, if using.

Step 2

Mix the flour with the baking soda and salt in a large bowl and then set aside.

Step 3

In a separate bowl, mash the bananas with a fork, then beat in the sugar with an electric mixer for 3 minutes.

Step 4

Add the melted butter, eggs, and vanilla. Mix until well combined, and make sure to scrape down the sides of the bowl once or twice.

Step 5

Stir the dry mixture into the wet ingredients until about half incorporated. You should still see streaks of flour.

Step 6

Add the nuts and any other extras, then gently mix by hand until you no longer see streaks of flour. Stop right away to keep from overmixing.

Step 7

Spoon the batter into the muffin tin until each mold is half-filled. Gently tap the tin on a flat surface to remove air bubbles.

Step 8

Bake the muffins for 18 to 20 minutes or until a toothpick inserted into the center comes out clean (a few crumbs are okay).

Step 9

After baking, let the muffins cool at room temperature before taking them out of the muffin tin. Serve warm, and enjoy!
