Peanut Butter M&M Cookies

Preheat an oven to 350ºF. Line 2 large baking sheets with parchment paper or Silpat.

In a large bowl, combine the sugars, butter, shortening, peanut butter, eggs, and vanilla. Cream together on medium speed until smooth and fluffy. Add flour, oatmeal, baking soda, and salt. Mix on low speed until combined. Stir in M&Ms by hand with a sturdy spoon.

Drop dough by tablespoons onto lined baking sheets, about 2 inches apart. Bake 12-14 minutes or until bottoms are light golden brown. Rotate pans halfway through baking.

Cool on baking sheet until cookies are firm enough to handle. Transfer to wire rack and finish cooling. Store leftovers in an airtight container.
