Place peeled bananas (make sure they are very ripe) into bowl of stand mixer. Using paddle attachment, cream bananas until well mashed.
Add remaining ingredients into mixing bowl. Turn mixer onto lowest setting and mix until all ingredients are incorporated, being careful not to over mix.
Scoop batter into muffin tin, filling the muffin cups about 3/4ths full of batter. (I like using reusable silicone baking cups - the muffins come out easily and no cooking spray is needed.) With paper liners or no liners, you may need a small spray of oil to prevent sticking.
Bake at 325 degrees F for 20-25 minutes. When a toothpick inserted into the center of a muffin comes out clean, remove muffins from the oven. Enjoy with butter or your favorite dairy-free spread!
