Perfect M&M Cookies: All Butter, No Shortening

One of America's favorite cookies, M&M Cookies are an adaptation of the traditional Tollhouse Chocolate Chip Cookie recipe, topped with crayon-colored M&M candies. It's my friend Kathy's signature recipe, one she's tweaked and perfected over many years. Best of all, her cookie recipe uses butter, real butter, not shortening. Bake them crispy, bake them chewy, your choice. Festive & Colorful for Christmas & Other Holidays. A Favorite for Kids and Kids-at-Heart.
