Step 1

In a medium size mixing bowl, mash the banana. Then stir in the egg, vanilla extract, and oil until combined. Then, add all at once the flour, sugars, baking soda, and salt. Fold until combined. Then stir in the chopped walnuts.

Step 2

Spoon into your prepared (oiled or lined with parchment) baking vessels and bake at 325°F

Step 3

Regular size muffins or a baked donut pan will yield six and should be baked for 14-15 minutes.

Step 4

If you use mini loaf pans (like I have in the photos), this will yield three and should be baked for 18-20 minutes.
