Preheat the oven to 350 degrees F. Spray a muffin pan with butter flavored PAM, and set aside. Combine the flour, baking soda and salt in a large bowl.
In a separate bowl, mix the softened butter with the brown sugar until well creamed; add the eggs and mix in, then add the mashed bananas and walnuts. Add to flour and mix together very lightly. I like large muffins so I use an ice cream scoop to fill the muffin tins. This works out to fill 10 of the 12.
Bake at 350 degrees F for about 20 to 25 minutes, checking first at about 15 mins. Use a clean toothpick to insert in muffin to check - if the toothpick comes out clean, they are done. Let cool in the muffin tin for a few minutes, then remove to a wire rack to finish cooling. Yummy!
