I thought I would try to make the cookie cups, fill them with some sort of chocolate, and decorate them to look like cups of hot chocolate. It worked and it tasted really good too!
Make Tablespoon sized dough balls and roll them in some granulated sugar. This will help keep them from sticking to the pan. Then, press the dough balls in each muffin spot.
Immediately after removing the cookies from the oven, take a shot glass or medicine cup to make indentations in the middle of each cookie. This will form the "cup".
Make sure to let the cookies cool completely before removing them from the pan. Then, fill your cookie cups with your desired filling. (I like to use fudge for my filling).
