Mash bananas, add cake mix and eggs to a mixing bowl and mix with mixer until ingredients are wet. Spray a 9 x 5 loaf pan with cooking spray. Add batter and bake in preheated 350 degree oven for 45 to 50 minutes testing center to see if done.
Notes
I stirred in 1 cup each of maple flavored chips and walnut pieces to my batter sprinkling a few on top before baking. You can add whatever you like to your recipe.
