Applesauce-Oatmeal-Spice Cake

1 3/4 cups applesauce

1 cup quick-cooking oats

1/2 cup butter

3/4 cup packed brown sugar

1 egg

1 1/2 cups all-purpose flour (I used 1 cup flour and 1/2 cup oat bran)

1 teaspoon baking soda

1 heaping teaspoon ground cinnamon

1/2 teaspoon salt

1/2 teaspoon ground cloves

FROSTING:

2 cups confectioners' sugar

2 tablespoons butter or margarine, softened

2 tablespoons milk

1/2 teaspoon vanilla extract

1. In a small saucepan, bring the applesauce to a slow boil. Stir in oats; remove from the heat. Cover and let stand for 20 minutes.
2. In a mixing bowl, cream butter and brown sugar. Add egg; mix well. Combine the flour (and bran, if using), baking soda, cinnamon, salt and cloves; add to the creamed mixture alternately with applesauce mixture. 
3. Pour into a greased 8-in. square baking pan. 
4. Bake at 350 degrees F for 40-45 minutes or until a toothpick inserted near the center comes out clean. Cool on a wire rack.
5. In a mixing bowl, combine the frosting ingredients; beat until smooth. Frost cooled cake.
