Preheat oven to 380 F, and line 24-25 cupcake tins. In a large mixing bowl, combine all dry ingredients and stir very well. In a separate bowl, combine and stir all wet ingredients (including banana). Mix wet into dry, then pour into the cupcake liners and bake 21 minutes. I also like to then broil for 1-2 minutes, but it’s optional. These oatmeal cakes can be eaten right away, or they can be frozen and reheated for an instant breakfast on a busy day.
