1/4 cup brown sugar
1/2 cup oil
2 eggs
1 cup mashed banana
1 3/4 cups flour (white, whole wheat, or a combination)
2 teaspoons baking powder
1/2 teaspoon baking soda

Combine ingredients and stir only until smooth. Pour into a greased loaf pan. Bake at 350 degrees F for about 1 hour or until firmly set.

Cool, remove from pan, and cut into sticks. Spread sticks out on a cookie sheet and bake at 150 degrees F for 1 hour or longer until the sticks are hard and crunchy. Store in a tightly covered container.
