Instructions

1 In a large bowl, mix together butter or margarine, sugar, eggs and vanilla. Set aside.

2 In another bowl, sift together flour, salt, soda, and baking powder. Add these dry ingredients to the creamed mixture. Add sour milk and bananas to the batter. Beat together well.

3 Line two 9 inch round cake pans, or one 9 x 13 inch pan with wax paper; the pans can be greased and floured instead, if desired. Bake at 350 degrees F (175 degrees C) for 17 to 20 minutes for the layered cakes, or for 25 to 40 minutes for the sheet cake.
