1 cup shortening
2 cups white sugar
2 eggs
2 tablespoons mayonnaise
6 very ripe bananas, mashed
3 cups all-purpose flour – We use http://amzn.to/2zM6Ssd
1/2 teaspoon salt
1 teaspoon baking powder – We use http://amzn.to/2zMy1NM
2 teaspoons baking soda – We use http://amzn.to/2hEzfUy
1 cup semi-sweet chocolate chips
1/2 cup chopped walnuts – We use http://amzn.to/2hHvaPF

1. Preheat oven to 350 degrees F (175 degrees C). Lightly grease two 9×5 inch loaf pans.
2. 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.
3. 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.
