Blend sugar, butter and oil in a large bowl with an electric mixer until it turns a little fluffy and lighter in color. Mix in bananas, eggs, vanilla and peanut butter . In a separate bowl mix flour, salt and baking soda; add to banana mixture and mix just until combined. Stir in chocolate and peanut butter chips.
Pour mixture into a greased and floured 9x5' loaf pan. Bake at 300 degrees for approx 1 1/2 hours, or until a knife inserted in the middle comes out clean. Makes 10, big gorgeous slices!
