Preheat oven to 350 degrees Fahrenheit.

Slice cookies, and bake for 10-12 minutes or until you can place a took pick into the center and it comes out clean.

Remove cookies, and transfer to a cooling rack.

Create a flag using the m&m candies while the cookies are still warm. If you slightly press the m&ms into the cookies, before they cool, the m&m candies will stick in place.
