3/4 cup butter, margerine or shortening
1 cup brown sugar
1 egg, beaten
1 1/2 cups flour (I use 1/2 whole wheat, half white or a combination of gluten-free flours)
1/2 tsp. soda
1 tsp cinnamon
1/4 tsp nutmeg
1 cup mashed banana
1 3/4 cups oatmeal, uncooked (this means regular or quick cooking oats, not the instant kind)
Cream butter with sugar and then add the egg and mix well.
Mix flour, cinnamon and nutmeg together and add to creamed mixture and blend till smooth. Add mashed banana and oatmeal next. Blend. Drop by teaspoonfuls onto a greased sheet and bake at 400 for 12-15 minutes.
(You could also throw in some raisins, if you like.)
