This is a recipe from my "adopted" grandmother -
1/2 cp butter
1/2 cup sugar
2 eggs
Cream together.
1 3/4 flour
1 tsp soda
1 pinch salt
Mix together
Combine the two by adding 1/2 cup buttermilk - alternating with the flour.
Add 3 medium mashed bananas
1 cup nuts
1/4 tsp vanilla
Bake 325* for 1 hours or longer.
