Now toss in your mix-ins: chocolate chips, peanut butter chips, M&M’s, and the kitchen sink. Mix all that in until combined.

scoop out cookies onto cookie sheet

Spray some cookie sheets with cooking spray and then make golfball sized rounds of cookie dough and put them about two inches or so apart.

Or eat them warm because that is extra delicious.

Enjoy these cookies! Seriously everyone loves them, I know you will too!


  • Place them in an airtight container or zip-top bag to keep them from drying out or becoming stale. Let the cookies cool completely before storing them to prevent any of the chocolate from melting on the bag.
  • For longer storage, you can freeze monster cookies in a single layer on a baking sheet before transferring them to a freezer-safe container. When you’re ready to enjoy them, just thaw them at room temperature or give them a quick zap in the microwave for that fresh-from-the-oven taste. 


Can I add other mix-ins into my monster cookies?

When it comes to monster cookies, the sky’s the limit when it comes to mix-ins! Here are some fun and flavorful additions you can throw into your monster cookie batter to take them to the next level:

  • Nuts: Chop up some walnuts, pecans, almonds, or cashews for added crunch and texture.
  • Coconut: Sweetened shredded coconut adds a tropical twist and a chewy bite to your cookies.
  • Dried Fruit: Try adding dried cranberries, cherries, raisins, or apricots for bursts of natural sweetness and tanginess.
  • Pretzels: Crushed pretzel pieces can add a salty crunch that contrasts beautifully with the sweetness of the cookie dough.
  • Butterscotch Chips: Swap out some of the chocolate chips for butterscotch chips for a rich, caramel-like flavor.
  • Candy Bars: Chop up your favorite candy bars – like Snickers, Reese’s Peanut Butter Cups, or Kit Kats – and fold them into the dough for extra decadence.
  • Toffee Bits: Bits of toffee add a buttery, caramel flavor and a satisfying crunch to your cookies.
  • Peanut Butter Chips: Double down on the peanut butter goodness by adding peanut butter chips along with the creamy peanut butter in the dough.
  • White Chocolate Chips: For a sweeter, creamier twist, mix in some white chocolate chips along with the semi-sweet or dark chocolate ones.
  • Pumpkin Seeds: Add a nutty flavor and a bit of crunch by tossing in some roasted pumpkin seeds (pepitas).

Feel free to mix and match these mix-ins to create your own unique monster cookie masterpiece. The only limit is your imagination!

  1. This recipe sounds delicious! I can’ wait to try it. I so enjoyed your “letter”. Thank you for including us in your everyday life and keeping us updated as to what is going on! I am excited about your Mom helping with the blog and recipes, etc. Also, thank you for your quotes and words of wisdoms and scripture verses, they are a huge encouragement to me!


  2. Im gona have to make these. I made a different recipe of these cookies & they werent exactly great. I will try your recipe & will just use 2 teaspoons of baking powder. Also, I like using pudding mix in cookies so I will substitute one cup of oats for one 3.4 ounce of Jello brand instant vanilla pudding mix. And I will add one tablespoon of corn syrup, which with the pudding mix give a tender center to the cookies. Placing the dough in the fridge 30 before baking & in between baking times will help too. I’ll bake 9 mins & leave on baking sheet 5 minutes before moving to cooling rack where they will continue to firm up. Thanks so much for your recipes!

  3. Hi! I just made a batch of these tonight for a bake sale at a yard sale to benefit animal rescue on Saturday. 😉 (I couldn’t decide what kind of cookies to make, which is the best reason to make monster cookies, in my opinion — because they have EVERYTHING in them!) These are perfect cookies! The lack of flour makes them way chewy. I definitely suggest popping the dough in the fridge between batches because I had to do three runs in the oven with these; I had a total of 51 cookies. Also, before I added all the fun candies and chips, my little 4.5 qt KitchenAid was struggling with all the dough, so I mixed the candy in by hand. Worth it! 🙂

  4. I would like to make these in bar form. What size pan and baking time do you recommend? Thank you!
