Lightened-Up Buttery M&M Cookies

Heat oven to 350 F. Line two baking sheets with parchment paper; set aside.

In a medium-sized bowl, add flour, cream of tartar, salt and baking soda; set aside.

In a large bowl add butter, brown sugar and granulated sugar and beat until light and fluffy. Beat in egg and vanilla extract until creamy. Beat in flour mixture, until just incorporated. Gently stir in M&M’s.

Using a cookie scoop, drop scoops of the cookie dough about 2″ apart on prepared baking sheet. Bake 9 to 11 minutes or until lightly browned around edges. Remove pan from oven and set it on a rack. Cool cookies on the pan slightly then remove them from the cookie sheet to a wire rack. Cool completely.
