Begin by preheating your oven to 350 degrees. Next, soften your butter in your microwave. You’ll want to soften it, not completely melt it.
Add your flour, sugar, salt, baking powder, and baking soda to a large mixing bowl. Stir with a large spoon until well mixed.
Next, slowly add in all of your wet ingredients.
Peel and mash your bananas with a fork then add them in.
Mix with a hand mixer for about three minutes or until the batter is no longer lumpy.
If desired, stir in 1 cup of walnuts or pecans into your batter and stir well.
Pour your batter into a greased loaf pan and then bake at350 degrees for 55 to 60 minutes. You will know your banana bread is done because a toothpick will come out clean from the center.
