These M&M cookies are soft, chewy & gigantic. It's an easy cookie recipe that turns out just like your favorite cookies from the bakery. Use regular or mini M&Ms.
Preheat the oven to 350F (180C) degrees. Line cookie sheets with parchment paper or baking mats.
In a large bowl beat together the butter, brown sugar and granulated sugar until creamed (about 2 minutes)
Beat in the egg and vanilla extract.
Add in the flour, cornstarch, baking soda and salt. Start with the mixer on a low speed and gradually increase to medium speed until combined. Turn off the mixer and squeeze a ball of dough in your fingers. If it sticks to your fingers, beat in 1 to 2 more tablespoons of flour.
Turn off the mixer and stir int he M&Ms and chocolate chips.
Form the dough into balls with about 1 ½ tablespoons of dough each (I use a cookie scoop). Place 2 inches (4-5 cm) apart on the lined cookie sheets.
Bake 1 sheet at a time in the middle of the preheated oven for 9-11 minutes, or until the tops are just set.
Once out of the oven, optionally place a few extra M&Ms and chocolate chips on the top of each cookie.
