My family loves this cake from BH&G. Place 2tsp lemon juice in measuring cup and add milk to make 2/3 cup. Sift 2 1/3 cups reg. Flour, 1 2/3 cups sugar, 1 1/4tsp. Baking powder, 1 tsp baking soda and 1 tsp salt into large bowl. Add 2/3 cups shortening, 2/3 cups mashed fully ripen banana and sour milk. Mix just until flour is dampened. Beat for 2 min. Add 2eggs, beat 2 more min. Stir in 2/3 cups chopped walnuts. Bake in 2 greased 9” pans 350 degree oven 35 min. Cool ten minutes. I always make sure the bananas I use have almost black skins so the cake has really good flavor. My family loved whipping cream and sliced bananas between the layers and on top too.
