- ¼ teaspoon salt
- 1½ cups quick oats

Preheat oven to 350°. Line cookie sheets with parchment paper, use a silpat liner, or spray with cooking spray.

** These cookies don't spread much after baking. If you gently press additional m&m's onto the tops of each cookie that will help flatten the cookie to more of a "cookie shape". You can also tap the hot cookie sheet against the countertop or stove top to help the cookies to fall.
