Tips from the Betty Crocker Kitchens

  • tip 1
    We love this easy recipe for monster cookies so much, we made a how-to video. Watch How to Make Easy Monster Cookies to see this recipe in action.
  • tip 2
    To keep your cookies big and thick, wait until your cookie sheets have cooled before scooping out your dough. This prevents them from starting to spread out before getting in the oven.
  • tip 3
    Would you rather make 36 smaller monster cookies instead of 18 big ones? Place two heaping tablespoonfuls of dough about two inches apart on ungreased cookie sheets. Bake for 10-12 minutes or until light golden brown.
  • tip 4
    If you are using larger packets of cookie mix (which comes out to 20% more cookie mix), add 3 tablespoons of water to the cookie mixes, oats, butter and eggs. Prepare the rest as directed and the yield will be 22 cookies.
  • tip 5
    Don’t have any cookie mix in your cupboard? Check again and see if you have a box of Betty Crocker™ yellow cake mix? We love this equally-easy but delicious recipe for Cake Mix Monster Cookies.

More About This Recipe

  • Oaty, chewy, chocolatey and easy? These might just be the cookies of your dreams! Classic monster cookies are a mashup of favorite cookie ingredients — oats, chocolate chips, peanut butter and M&M’s in a yummy brown sugar base. For this recipe, which you can truly throw together on the fly when you’re craving something sweet, we used a shortcut step in the form of Betty Crocker chocolate chip cookie mix and peanut butter cookie mix. The result is a cookie that’s rich and chock-full of goodness but still perfectly tender. Pack them in a lunchbox, bring them on a hike or just grab one after dinner — there’s no bad time to enjoy a monster cookie! If you love these but have a little more time on your hands, or want to get creative, try out one (or more!) of our other monster cookie recipes.
