Among the worst ways to get rid of extra Halloween candy? Make cookies with it. Because then you have to eat both candy and cookies, which is completely counterproductive.
I'm not really a fan of plain M&M's, but M&M cookies? Soooooo good! And really fun to make with your kid.
These babies are HUGE! So big we had to share with the neighbors and freeze some for later. Great recipe from Joy of Baking website.
