Ingredients:

• 1/4 cup butter, softened
• 1/2 cup sugar
• 1 large egg
• 1/2 teaspoon vanilla extract
• 3/4 cup mashed ripe bananas (about 3 medium)
• 3/4 cup all-purpose flour
• 1/2 teaspoon baking powder
• 1/2 teaspoon baking soda
• 1/4 teaspoon salt
• 1/8 cup baking cocoa

Directions:

In a large bowl, cream butter and sugar until light and fluffy. Beat in egg and vanilla. Stir in bananas. Combine the flour, baking powder, baking soda and salt in separate bowl. Add to creamed mixture and mix well.

Divide batter in half. Add cocoa to half; spread into a greased 13 x 9 baking pan. Spoon remaining batter on top and, if desired, swirl with a knife to marble batter.

Cool and enjoy!
