This is pretty simple, really.
Step 1: Buy pre-made dough from local grocer (makes something like 24 cookies), put on cookie sheet, then put in oven.
Step 2: Wait about 9-10 minutes.
Step 3: Pull the cookies out of the oven. Wait a few minutes. Enjoy!

I love cookies, and doing this is so much nicer than going to the store and buying a pre-wrapped pack of icky, crunchy cookies. One variation I sometimes make: add some Reese's peanut butter chips into each little cookie dough ball, and then bake - I love peanut butter!
Another note: You might not want to eat all 24 cookies in the same sitting. Also, you can take a few cookie dough pieces and mash them together to make a giant cookie if you want. Those things have nice, soft, gooey centers!
