Cover a baking sheet with parchment paper.

Roll the cookie dough into balls and place them on a baking sheet lined with parchment paper.

Cook at 350° for 8 minutes.

Once done, gently flatten the cookies, sprinkle chopped cookies on the bottom half of the cookie, then add 2 eyes to each cookie. Remember that Cookie Monster’s eyes are a little wonky, so place them accordingly.

Let cookies rest for 5 minutes and remove to a cookie rack for further cooling.
