I just made these today and they turned out perfect.
Black Bottom Banana Bars
1/4 cup soy butter 1/4 cup applesauce 1 cup sugar 2 egg whites 1 teaspoon vanilla 1-1/2 cups mashed ripe bananas (about3) 1-12/ cups flour 1 teaspoon baking powder 1 teaspoon baking soda 1/2 teaspoon salt 1/4 cup cocoa
In a mixing bowl, cream butter and sugar. Add egg, applesauce, and vanilla; beat until thoroughly combined. Blend in the bananas. Combine the flour, baking powder, baking soda and salt; add to creamed mixture and mix well. Divide batter in half. Add cocoa to half; spread into a greased 13-in.x9-in.x2-in baking pan. Spoon remaining batter on top and swirl with a knife. Bake at 350 for 25 minutes or until the bars test done. Cool. Yields 2-1/2 to 3 dozen.
