"Peanut butter flavor molecules can be trapped by flour in baked applications, so we ratcheted up the flavor’s intensity by sandwiching an uncooked peanut butter filling between our cookies. Adding a full cup of confectioners’ sugar to the filling made it firm enough to stay in place, and we balanced the sweetness with a relatively low-sugar cookie component. Extra liquid and extra baking soda gave our cookies the thin, flat dimensions and sturdy crunch that are vital to a sandwich cookie...."
