I hate it when I read the words, "There really are no words to describe…" My reaction is always, "Really? Really Ms. Writer? No words? That is your job. Go and find the words. When you do, report back to the rest of us. Thanks!"
Well, when I took my first bite of these whoopie pies, I heard myself saying, "Oh my! There are no words." A snack cake rendering me speechless? You know that is one amazing snack cake. I'll try to describe this luscious cake with the admonition: Once you've read the description you must, you must(!), go and bake a pan for yourself.
This is a classic whoopie pie. It's made up of two moist, flavorful, chocolately cakey-cookies held together with sweet, cloud-light icing. If you've never seen a Whoopie Pie (they are popular in the Northeast, especially Maine.) they look like an Oreo Cakester. However, an Oreo-cakester would take one look at these whoopie pies and hide itself in shame. An Oreo-Cakester is a pale, pale imitation of a Whoopie Pie.
The cake recipe contains brown sugar. I know that is a bit surprising. I don't often think of the earthy flavor of molasses as a complement to chocolate. Yet, it works. The molasses flavor fades into the background, adding just a base note and, somehow, amping up the chocolate flavor. You could eat these cakes on their own. But why would you want to? The icing, lovingly, borrowed from the Twinkie Recipe in my cookbook, puts this recipe over the top. WAY over the top. It is sweet and soft with just the slightest hint of vanilla.
Not only are these Whoopie Pies swoon-worthy, they are also easy to make. So, what are you waiting for? Go and find the ingredients and make some Whoopie (Pie)!
