I'm not a very good cookie maker. My cookie skills are basically just the store bought dough or packaged just add butter, egg, and water kind. I haven't strayed much from just adding sprinkles and would like to try a few things with premade dough as from scratch just doesn't work too well for me. My questions: 1. I want to add a chocolate kiss or peanut butter cup to the center, do I do this immediately after they come out of the oven, half way through cooking, or is it even doable with premade cookie dough? 2. I would also like to make the type with jam in the center. Can I do with with the premade sugar cookie dough and if so when? 3. Any suggestions for homemade peanut butter cups? Thanks.
