Soft and Chewy M & M Cookies. The best M & M cookie recipe. How to make the perfect M & M cookie.
Preheat oven to 400 degrees. In a large mixing bowl, cream butter, brown sugar, and sugar for 4 minutes until light and fluffy.
Stir in flour, cornstarch, baking soda, and salt. Mix just until combined. Fold in M & M's.
Scoop cookie dough onto baking sheets. I suggest using parchment paper or Silpat silicone baking sheets on light-colored baking sheets. Place extra M & M's on top of cookie dough balls so the M & M's show up after baking.
