Banana Cake(By Mrs. Edmund G. Brown, Former First Lady Of California)  
["3 medium fully ripe bananas (1.5 c.)", "1 c. walnuts (I leave out)", "3/4 c. buttermilk", "2 egg whites", "2 egg yolks", "2 c. all-purpose flour", "2 tsp. baking powder", "1 tsp. baking soda", "1/2 c. butter", "1 tsp. vanilla extract", "1.5 c. sugar (I use fructose)"]
["Sift flour, baking powder and baking soda together; set aside. Cream butter with extract; gradually add fructose, creaming thoroughly.", "Add egg yolks, one at a time, beating well after each addition.", "Sieve bananas and mix with buttermilk.", "Beating only until smooth after each addition, mix the creamed butter extract, 1/4 dry ingredients and 1/3 of the banana mixture; repeat 1/4 dry and 1/3 banana until all is mixed, then stir in optional walnuts. Fold in the beaten egg whites gently into the batter until thoroughly blended.", "Turn batter into 2 prepared (vegetable grease and flour) pans; spread evenly to edges.", "Bake at 350\u00b0 for 25 to 30 minutes or until cake tests done.", "Cool on wire racks and frost with a buttercream frosting (I don't frost; after cooling I place in the refrigerator 3 to 4 hours or overnight, it's best served cold)."]
