When she was little, Chuckie had an obsession with those Little Debbie Oatmeal Creme Pies... so we re-created them for her birthday, in lieu of a birthday cake. And by "we," I mean Tony baked them on his day off while I provided moral support to him over IM from my cube at work. He's a novice baker, but after a few minor missteps, he was victorious in the end. And now he knows what "cream" means in the baking context... and knowing is half the battle.
Using a recipe I found on a blog, they came out pretty close to the original- soft oatmeal cookies with a gooey marshmallow frosting on the inside. I think maybe if we were to make them again, we would try to use less sugar... they were borderline cloyingly sweet. But tasty nonetheless.
