Grandma's Banana Bread

my grandmother's recipe. the best ever!!!!!!!

1/2 cup butter, margarine or shortening (Grandma uses hard margarine)
1-2/3 cups sugar
2 eggs, slightly beaten
1 tsp salt
1-1/2 tsp baking powder
1/2 tsp baking soda
4 tbsp sour cream
4 cups mashed bananas (approx 2-3 bananas)
2 cups flour
1 tsp vanilla

cream together margarine and sugar until light and fluffy.
add eggs and salt. mix well.
dissolve baking powder and baking soda in sour cream and add to mixture.
stir in banana pulp.
gradually add flour and vanilla.
spray the inside of soup cans (like Campbell's soup) with cooking spray (spray works best b/c it gets into all the ridges). fill cans about 2/3 full.
bake at 350F for about 1 hour. check after 45 minutes.
yields 4 "cans" of banana bread.

you can also make it in a loaf pan. bake at 350F for about 1.5 hours. check just after 1 hour.
