Ingredients

Instructions

  • Preheat oven to 350. In a large bowl, cream the butter, eggs, sugar, and brown sugar.
    Wet ingredients combined in a large bowl for Monster Cookie Dough. Wooden spoon and M&Ms on the side.
  • Add peanut butter, vanilla, Karo syrup, baking soda, and oats. Mix until combined.

Notes

  • Make sure to scrape the sides of the bowl after mixing. Such a big batch of dough can be difficult to handle, so make sure you're incorporating all of the ingredients in the bowl of a stand mixer.
  • Use a large cookie scoop to measure out each cookie so they bake evenly.
  • Space the cookie dough balls out really well on the baking sheet so they don't run into each other while they bake.
  • Make sure you don't over-bake these cookies; they're best when they are soft! 
  • If you're looking for a smaller batch, simply cut the recipe in half (or even fourth) and the recipe will still turn out great!
