Ingredients
Method
- Preheat oven to 350°F (180°C) and line two baking sheets with parchment. Beat butter, brown sugar, and granulated sugar until fluffy. Add peanut butter, eggs, and vanilla; beat until smooth.
- Mix in baking soda, salt, and oats. Fold in M&Ms and chocolate chips until evenly distributed.
- Drop 2-tablespoon scoops of dough onto sheets, 2 inches apart. Bake 10 to 12 minutes until edges are golden.
- Cool on the baking sheet for 5 minutes, then transfer to a wire rack. Press extra M&Ms onto warm cookies.
Notes
The cookies will look slightly underdone in the center when you take them out; they firm up as they cool. For a polished look, press a few extra M&Ms onto the tops right after baking while the cookies are still hot.
