Preheat the oven to 350°F (175°C). Line a baking sheet with parchment paper or a silicone mat.
In a medium bowl, whisk together the cake mix, eggs, and vegetable oil until a soft dough forms.
Gently fold in the M&M’s baking bits.
Use a tablespoon or cookie scoop to drop rounded dough onto the prepared baking sheet, spacing them about 2 inches apart.
Bake for 8 minutes or until the edges are set and the tops are just beginning to crack.
Let cookies cool on the baking sheet for 5 minutes before transferring to a wire rack to cool completely.
Notes
Store cooled cookies in an airtight container at room temperature for up to 3 days, maintaining their chewy center.For a make-ahead twist, freeze dough balls on a baking sheet, then transfer to a sealed bag. Bake from frozen, adding 1–2 minutes to the cook time.
