Ingredients

Instructions

  • Preheat your oven to 350 degrees Fahrenheit. Prepare a baking sheet with parchment paper and set it aside.
  • To the bowl of your stand mixer add the butter, brown sugar and white sugar and beat on medium speed until they're combined and smooth, and the butter is completely incorporated. Next, beat in the peanut butter, eggs, vanilla and molasses on medium speed until everything is incorporated.
  • In a separate bowl, combine the flour, the oats, the salt and the baking soda. whisk these ingredients together just to make sure the baking soda is evenly distributed throughout the dry ingredients.
  • Add the dry ingredients to the bowl of the stand mixer with the other mixture and mix on low speed just until everything is combined.
  • Remove the bowl from the stand mixer and dump in the M&Ms. Mix these in by hand with a rubber spatula or a wooden spoon.
  • Using a tablespoon and your hands (the dough will be very sticky), drop the dough on the prepared baking sheet about 2 tablespoons at a time (12 to a sheet).  Trying to form the dough into tight balls will seem futile...the dough is sticky and falls apart easily, so scooping the dough with the tablespoon and forming it in the spoon with your hands is your best bet.
  • Bake the cookies in preheated oven (350 degrees Fahrenheit) for about 8-9 minutes or until the tops of the cookies just lose their shine.
  • Remove pan from oven and let the cookies cool on the baking sheet for about 5 minutes, then transfer the cookies to a cooling rack to cool completely. If you try to move the cookies right after removing them from the oven, they'll probably fall apart.

Notes

If desired, replace 1/2 cup of the M&M's with 1/2 cup crushed or chopped salted peanuts.
