Do you need to chill the dough for this Peanut Butter M&M Cookie Recipe?

Yes, you really do need to chill the cookie dough for this recipe! The cookies just won’t bake as intended if the dough is not chilled.

But do not worry, only 30 minutes of chilling is required. None of that overnight nonsense! And you can still have these cookies ready to eat in about 1 hour.

Peanut M&M Cookie tips…

Follow the tips below for the perfect cookies each & every time:

  • Chill your dough! This makes the cookie dough easier to work with, allows the flavors to develop further, and helps the cookies bake the way they are intended to.
  • Bang the pan! This gives the cookies a slightly crackly top and flattens them out. It also makes them extra chewy!
  • Let cool! Peanut Butter M&M Cookies will continue to finish baking and setting even after you remove them from the oven. That is why it is important to let them sit for a few minutes before touching them.
  • Add more M&Ms! When you mix the M&M candies into the cookie dough they get a little lost in the sauce. I love to really stud the top of the cookies with extra M&Ms right before baking … this way the cookies have a beautiful & colorful look when done!
