I have made these delicious treats for years. To me, they taste similar to those little snack cakes of years ago, "Hostess' Susie Q's"......only better! I got this recipe from a PBS cooking show in the early 80's. I'm not really sure of the prep and cooking time it takes to make these because I don't pay close attention to the time when I am cooking. I would say approx. 1-1/2 -2 hours from start to finish. This makes 15 large whoopie pies, but you can make them smaller. These freeze very well.
