Preheat oven to 350°F. Line 2 baking sheets with parchment paper or silicone mats.

Break apart cookie dough and place 2 inches apart on prepared baking sheets.

Press about 10 M&Ms onto the top and sides of each cookie dough ball.

Bake for 12-16 minutes until light golden and no longer glossy around edges.

Cool for 10 minutes on the baking sheet before transferring to a wire rack. Store in an airtight container for up to 3 days or freeze for up to 3 months.
