1 c shortening
2 c white sugar
2 eggs
2 T mayonnaise
6 very ripe bananas, mashed
3 c all-purpose flour
1/2 t salt
1 t baking powder
2 t baking soda
1 c semi-sweet chocolate chips
1/2 c chopped walnuts
Preheat oven to 350 degrees F (175 degrees C). Lightly grease two 9x5 inch loaf pans.
In a large bowl, cream together the shortening and sugar until light and fluffy. Stir in the eggs one at a time, beating well with each addition. Stir in the mayonnaise and bananas. Stir together the flour, salt, baking powder and baking soda. Blend the flour mixture into the banana mixture; stir just enough to evenly combine. Fold in the chocolate chips and walnuts.
Bake at 350 degrees F (175 degrees C) until a toothpick inserted into the center of the loaf comes out clean, about 50 to 75 minutes. Cool loaf in the pan for 20 minutes before removing to a wire rack to cool completely.
