These cookies are the real deal. The cookie part is a dead ringer for Little Debbie Oatmeal Creme Pies (without that annoying chemical afterburn). The filling is very close texturally, but I truly couldn't bring myself to use shortening in it, so it's buttery-er than the original. If that's a bad thing, sue me. And if you'd prefer a marshmallow filling, do check out Stella's recipe. I can guarantee you will not be disappointed. Yes, you do have to use a scale to make these cookies. Most of the measurements are in ounces. Some of the smaller measurements are in grams. This is no problem with most scales since most will go back and forth between metric and standard weights with the press of a button. If your scale doesn't have that button, you'll need to do the conversions yourself. An ounce equals 28 grams. You will need an instant read thermometer to make the creme filling.
