Ingredients:

7 ripe medium bananas, mashed
1/2 cup unsweetened apple sauce
2-1/2 cups unbleached all purpose flour (I used whole wheat flour, though)
1-1/2 tsp baking soda
1/2 tsp salt
4 tbsp butter, softened
1 cup light brown sugar
4 large egg whites
1 tsp vanilla extract
3 oz (3/4 cup) chopped walnuts
baking spray

Directions:

Preheat oven to 350°. Grease two 8x5 inch loaf pans with baking spray.

In a medium bowl, combine flour, baking soda and salt with a wire whisk. Set aside.

In a large bowl cream butter and sugar with an electric mixer. Add egg whites, bananas, apple sauce and vanilla, and beat at medium speed until thick. Scrape down sides of the bowl.

Add flour mixture and walnuts, then blend at low speed until combined. Do not over mix.

Pour batter into loaf pans and bake on the center rack for 50 minutes, or until a toothpick inserted in the center comes out clean.

Let the pan cool at least 20 minutes, bread should be room temperature before slicing.

I just made this for the first time and good God... it's a great one. Definitely will be my go-to one from now on. It also calls for an electric mixer, but I didn't have one so I used a vigorous motion with my hands. I did one loaf with 1/3 cup of walnuts and the other with 1/3 cup of semi-sweet chocolate chips. Just delicious.
