Yum--this is so good! And it's a delicious way to use up overripe bananas.

3 eggs, separated

1 1/2 c. sugar

1/2 c. buttermilk

1/2 c. margarine

2 c. all-purpose flour

3/4 tsp soda

2 tsp. baking powder

3 medium bananas, ripe and mashed

2 tsp. vanilla

1 cup chopped walnuts

2 heaping tablespoons of peanut butter

1. Preheat oven to 350 degrees.  Grease a large rectangular glass baking dish and sprinkle with flour to prevent cake from sticking.

2. Mix egg yolks, sugar, buttermilk, margarine, bananas, vanilla, peanut butter and walnuts.

3. Sift [twice] the flour, soda, and baking powder. Add this to egg yolk mixture.

4. In a cold, stainless steel bowl using a mixer, beat the egg whites until they are stiff and white. Gently fold into the cake batter. Spread in a large rectangular  glass baking dish.

5. Bake for 1 hour or until toothpick in center comes out clean.

Enjoy!  It's great with a cup of English Breakfast tea or a cup of coffee.
