I guess I needed some humble pie, so that KW (Kitchen Witch, Grub Goddess, whatever!) smacked me up side the head and stole my baking mojo! That's the only explanation I can come up with for what happened after I wrote that post.
I did find a recipe on one of the blogs I follow for brownie cookie sandwiches with vanilla frosting centers , which I thought might be an acceptable subtitute for said whoopie pies. I folllowed the recipe
directions... they were simple enough. Of course, I was totally unsuspecting that I had been robbed by the Goddess of Gastronomy. "Drop by spoonfuls on cookie sheet and bake 8 or 9 minutes." I did as instructed, put the pan in the oven, and guess what? Those suckers spread out to paper thin and ran together and baked up like a piece of chocolate tissue paper. There was no peeling them off the cookie sheet. They literally disintegrated into a bunch of crusty, chocolate, CRUMBS!
"I read receipes the same way I read science fiction: I get to the end and think.......well, that's not gonna' happen!"
There may be truth to the "If you don't use it, you lose it" maxim, after all!
