Set your oven at 350°F to preheat. Grab an 8x4-inch loaf pan and coat it well with nonstick spray.

In a big mixing bowl, mix your mashed bananas, melted butter, sugar, egg, and the vanilla together.
03 -
In a smaller bowl, stir your dry ingredients together: gluten-free flour, baking soda, baking powder, and salt.
04 -
Pour the dry stuff into the wet mix and stir until everything’s just mixed. The batter will stay bumpy because of the bananas.
05 -
Transfer the mixture into your greased pan and bake for about 50 to 60 minutes, or until nothing sticks to a toothpick when you check.

Let the bread cool for 15 minutes in the pan. Then take it out to cool fully on a rack before slicing it.
