5 tablespoons butter
1/2 cup granulated sugar
1/2 cup firmly packed light brown sugar
1 large egg
2 egg whites
1 teaspoon vanilla extract
1 1/2 cups mashed, very ripe bananas
1 3/4 cups all-purpose flour
1 teaspoon baking soda
1/2 teaspoon salt
1/4 teaspoon baking powder
1/2 cup heavy cream
1/3 cup chopped walnuts
1 cup blueberries
Or experiment with other fruit and/or nuts
Preheat oven to 350 degrees F. Spray bottom only of 9 x 5 x 3 inch loaf pan with nonstick cooking spray. Please do not spray your pan if your cookware says not to. (I have that kind of cookware, Baker's Secret)
Beat butter in large bowl with a electric mixer set at medium speed until light and fluffy. Add granulated sugar and brown sugar; beat well. Add egg, egg whites and vanilla; beat until well blended. Add mashed bananas, and beat on high speed for 30 seconds.
Combine flour, baking soda, salt, and baking powder in medium bowl. Add mixture to batter mixture alternating between the cream, and flour mixture; ending with flour mixture. Add any optional ingredient if you want. Please keep in mind that this recipe is all measured for one optional ingredient. I do not know how the recipe will turn out if you add multiples. (My favorite is blueberries!)
Pour batter evenly into prepared loaf pan. Bake for 1 hour and 15 minutes or until browned and toothpick inserted near center comes out clean.
Cool bread in pan on wire rack for minutes. Remove bread from pan; cool completely on wire rack. If you are having problems with removing the loaf, let it cool a little longer and try again. Slice and serve with butter, jam, cream cheese, or whatever you may like.
