Banana walnut cake

This is VERY easy, and VERY good!

Mix everything in the same bowl (I use a wisk to get out the lumps
but the batter is kind of thick)

1 1/4 cup sugar
1/2 cup veg oil
2 eggs
2 mashed bananas (ripe)
1 1/2 teaspoon vanilla
1 cup buttermilk or sour milk (not bitter milk!)
1 teaspoon baking soda
2 cups flour
1 teaspoon baking powder
1 cup finely chopped walnuts (the original recipe calls for black walnuts,
      but who has a cup of black walnuts?)

bake at 350 in a 9X13 inch pan for about 35 minutes- until the top is brown
and springs back when touched.  This cake needs no frosting!
