Instructions

In a large mixing bowl, combine the butter, sugars, egg, and vanilla, then beat on medium until creamy (about 3-4 minutes).
Add the flour, pudding mix, baking soda, and salt, then beat on low speed until just combined (about 1 minute).
Gently fold in the M&Ms and chocolate chips once the dough is mixed.
Using a larger cookie scoop or your hands, form 12 equal-sized mounds of dough, roll them into balls, and flatten slightly.
Place the balls of uncooked dough on a large tray and cover with plastic wrap.
Chill the dough in the fridge for 3 hours; this step is crucial for the cookies to bake properly.
Preheat the oven to 350℉ about 10 minutes before the dough is finished chilling and line cookie sheets with parchment paper.
Place the chilled dough balls on the baking sheet, spaced at least 2 inches apart, and bake for about 10 to 11 minutes.
The edges should be firm and the tops just set when removed from the oven.
If desired, press more chocolate into the soft tops of the cookies immediately after baking.
Let the cookies cool completely on the cookie sheet even if they appear slightly undercooked in the center.

Notes

Chilling the dough is essential for the right texture; unchilled dough may cause the cookies to flatten while baking.
Feel free to customize the amount of M&Ms and chocolate chips to suit your taste!
Store any leftover cookies in an airtight container at room temperature.
