                    This recipe calls for a jelly roll pan which makes 4 dozen bars. I prefer to cut the recipe in half and make an 8X8X2 cake. Baking time is the same. It's a wonderful treat and the frosting is lovely, creamy and smooth. Read more . From, Betty Crocker's Best of Baking.  Ingredients:
