    This is SO YUMMY and does taste like a gob (whoopie pie). I did not use the frosting. I used a much easier, fool proof recipe. Beat 3 cups powdered sugar with 1/3 cup softened butter. Add 1 teaspoon vanilla and gradually beat in 1-2 tablespoons of milk until frosting is spreadable. MMMMM!  -  04 Jun 2006  (Review from Allrecipes US | Canada)


    My husband can't stop raving about this cake. However, I didn't use the icing it suggested. I used a cream cheese icing instead... just because I had it leftover from another cake. We're originally from PA and this reminded us of home.  -  07 Oct 2005  (Review from Allrecipes US | Canada)


    I have to say, I have never had a whoopie pie or a "gob," but this cake tastes exactly like those little hostess chocolate cupcakes with the cream filling I remember eating as a kid. My husband, who is allergic to eggs and can't have most cakes, absolutely loved it. For me it was very easy to make with ingredients I always have on hand. It tasted great with caramel frosting. Next time I might try to inject some cream into it and frost it with chocolate frosting... maybe I'll even try cupcakes. There was no question in my husband's mind that this recipe gets 5 stars.  -  31 Mar 2007  (Review from Allrecipes US | Canada)
