Mix together wet ingredients first, then add dry ingredients. (If your bananas are frozen let them sit out on the counter for at least 10 minutes to thaw slightly but you can still pop them into the stand mixer frozen, though it'll be easier on your mixer if you break them into fourths.)
Place in 3 regular loaf pans that have been sprayed and floured (or sometimes I use Pam baking nonstick spray for convenience), and bake approximately 1 hour. Use a toothpick to check the center - if the toothpick comes out with dough attached, leave it for another 5 minutes.
Let cool completely before trying to remove from the pan.
