Add 1/4 cup flour if you feel the dough is soft.
If you work with cold dough you won't need to.
If you dough has warmed to room temperature I suggest adding the flour, or after you separate and for the cookie cups in the mini cupcake pan-refrigerate them for 10 minutes or so until the dough is chilled.
I'm sure any sugar cookie recipe will work too.
Peanut butter cookie dough would be delicious.
You can dust them with powdered sugar just before serving.
16 oz cookie dough will make approx.32 cookie cups
