Ingredients
  

  • ½ cup (1 stick) salted butter
  • 1 ¼ cups peanut butter
  • 1 cup sugar
  • 1 cup brown sugar
  • 3 eggs
  • 2 teaspoons corn syrup
  • 2 teaspoons vanilla
  • ½ teaspoon salt
  • 2 teaspoons baking soda
  • 4 ½ cups old-fashioned oats
  • 1 ½ cups semi-sweet chocolate chips
  • 1 10-ounce bag M&Ms or closest size

Instructions
 

  • Cream the butter, peanut butter, and sugars together with a mixer for 2-3 minutes or until fluffy. Add eggs, corn syrup, vanilla—mix until well combined. Then mix in salt and baking soda.
  • By hand, stir in the oats, chocolate chips, and M&Ms until completely combined. It will be very thick. Cover the dough and refrigerate at least 2 hours (this is not required but your dough will be less sticky).
  • When ready to bake, preheat oven to 350° F. Scoop cookie dough onto a cookie sheet lined with parchment paper or a silicon baking mat. Press down slightly and arrange a few M&Ms on the top of the cookie dough, if needed.
  • Bake approximately 10-12 minutes or until lightly golden and still very soft. Let sit for about 1 minute on cookie sheet and then carefully remove. Let cool on cooling racks.

Notes

Bake times will vary depending on the size of the cookies and the type of cookie sheets used. Watch carefully to avoid overbaking the cookies. Please note the cookies will firm up as they cool.
