This recipe is from my Mom, Mildred Kramer -- Burlington, Colorado.  I always remember the bright yellow frosting she would put over the tops of these very moist cookies. 

1/2 cup soft shortening
1 cup brown sugar
2 eggs
1 cup mashed bananas
2 cups flour
2 teaspoons baking powder
1/4 teaspoon baking soda
1/4 teaspoon salt
1/4 teaspoon cloves
1/2 teaspoon cinnamon
1/2 cup chopped nuts (optional)

Frosting

powdered sugar
milk
yellow food coloring

Cream together shortening, sugar, and eggs.  Stir in bananas.  Sift dry ingredients, stir in. Blend in nuts.  Chill about 1 hour.  Heat oven 375°F.  Drop rounded tablespoonfuls 2 inches apart on lightly greased baking sheet.  Bake 8 to 10 minutes.  Frost with bright yellow powdered sugar frosting.   Makes 2 1/2 dozen.
