In a darling, warm bakery on the side of the river, we came across this seasonal delight. The "Whoopie Pie", when made correctly is wonderful. I think the recipe that I have found mimics the taste we experienced in Chicago. Well worth the easy preparation for this taste of fall.
If you can stand a few minutes of bossy Martha Stewart who continually interupts her guests and tries to best them vis a vis her baking techniques, this is a great idea on how to make these tasty morsels.
