These Monster Cookies have a Christmas cookie twist and we call’m Santa’s favorite because they are totally Santa’s favorite! These cookies are filled with oats, peanut butter, mini chocolate chips, white chocolate chips, red n’ green peanut butter filled m&m’s, and red n’ green mini m&m’s.

If you haven’t already guessed it. These are your basic Monster Cookies, but what makes them a little extra special for Christmas is that I add a touch of cinnamon, green and red peanut butter m&ms, white chocolate chips, AND mini green and red m&ms. My goodness, they are good! If you’ve never had a Monster cookie you’re totally in for a special treat. These Monster Cookies are on Christmas crack!

The original recipe came from my mama and she’s been making Monster cookies since I was probably 5 years old. I won’t be doing the math for y’all today, but it’s been around for a while. I forgot to ask her where she had gotten the recipe before writing this, but my guess is she found it in a magazine. You remember finding recipes in magazines? Y’know before the internet was a popular thing? haha.

I gave my mama’s recipe a bit of a Christmas-y twist only because I am who I am and I love Christmas and I always have an abundance of different types of red and green m&m’s this time of year.

baking goodies and elf with a stuffed animal dog

Do you have an Elf on the shelf at your house? We do, but before you’re like “Oh my Gosh how do people have time for moving the dang elf around and doing all this stuff?” I don’t. I explained on Instagram the other day that our elf mostly hangs out in the Christmas tree or in Pepper’s doll house, but a few times during the Christmas season ZuZu (that’s her name) brings some special things for us to do together as a family like a Christmas-y craft project, a nice book, hot cocoa fixin’s, and once a year she even rummages through my cabinets and gets all the ingredients to bake Santa’s Favorite Monster Cookies. I don’t have the ambition to do a ton with the elf and I think it’s vital to not set a super high standard in our house when it comes to the elf because I’m a very forgetful person.

This is also a super kid friendly recipe. If your little one likes to help in the kitchen, I definitely recommend it! They can measure everything out with very little help from you. It’s perfect. As Pepper was measuring the different mix-in’s she yelled for me and said “Look mama a snow man!” Do you see it? It’s the perfect example of why seeing life through a child’s eyes is so fun. I would’a never seen a snowman had I been doing this alone.

I know this isn’t the normal kind of post you’re used to seeing around these parts, but it’s Christmas so I thought I’d post something special. Also, when I posted these cookies on Instagram I think I got about 200 messages asking for the recipe within 24 hours so I thought I’d better get it up! Answering 200-ish people is no easy task and this way it’s here for years to come and I can always reference it.

PS Please do not ask me the WW points or the calories. I don’t want to know.

Author: Star @ the skinny-ish dish


  • 1 cup sugar
  • 1 cup light brown sugar (packed)
  • 1 stick unsalted butter (room temp! not melted and not warmed up in the microwave)
  • 3 large eggs
  • cups peanut butter (chunky or smooth – do not use all natural)
  • 1 tbsp vanilla
  • 2 tsp baking soda
  • 1/2 tsp salt
  • tsp cinnamon
  • cups old fashioned oats
  • 1 cup (total) mixture of mini green and red m&ms and peanut butter green and red m&m's. *You can have all of one or the other. It's up to you. The mixture makes them extra yummy.*
  • 1 cup (total) semi sweet mini chocolate chips and white chocolate chips *You can have all of one or the other. It's up to you. The mixture makes them extra yummy.*
  • extra m&m's and chocolate chips to stick into the cookie for it to "look prettier" after they are done baking. *optional


  • Preheat oven to 350°F. Line baking sheet with parchment paper.
  • In a bowl cream together white and brown sugar with the butter until combined well and light and fluffy.
  • Beat eggs in one at a time and then beat in peanut butter, vanilla, cinnamon, baking soda, and salt until combined.
  • Add in the oats and mix together until combined well.
  • Stir in m&m's and chocolate chips.
  • Scoop 3 tablespoon sized cookie mounds onto cookie sheet and space them about two inches apart otherwise they will run into each other.
  • Bake the cookies for 12 minutes then remove them from the oven and allow them to cool for at least 10 minutes on the cookie sheet before moving them to a cooling rack to finish cooling.
    *The key to most cookie baking is having them almost under baked a bit when removing from the oven and slowly finish "baking" just enough while on the cookie sheet. The perfect texture!!

  1. Can I sub peanut butter with sunbutter for allergies? The only concern is it says not to use all natural so I am wondering if it’s an oil thing?

    1. Hi Ashley I’m sorry I haven’t tried with sunbutter, but will try to test that soon to add for possible substituion!

    1. Yep! Divide the the dough into small balls and arrange them on a parchment-lined baking sheet. Place the sheet in the freezer until the dough is mostly frozen then add to a bag or other freezer safe container. Best results use within about 3 months! =)

    So delicious and festive!
    Decided to make these this Christmas after being mesmerized by them since last year on Instagram. Easy to make and makes a nice amount of cookies. I used half mini m&ms half PB m&ms and semi sweet chocolate chip. Everyone loved them! Will make again.

    These are so good! They’re going to be a new Christmas staple around here. I ground up the rest of all the Christmas candy that was laying around the house and added them to the batter. Thanks for the awesome recipe as usual!

    These cookies are delicious and so festive! I played around with the choc chips/m&m ratios based on what we had but no complaints! The perfect consistency of chewy as well as sweet/salty. 10/10!!!!

    Literally the easiest cookie to make! I overcooked the first tray, but they were still delicious. The rest were absolutely perfect! I have been looking for a flourless monster cookie type recipe! I will be making these over and over!

    Just got done making these and they are DELICIOUS! But it made more than I realized. Is it better to cook all the dough and then freeze the actual cookies? Or can the dough be frozen to make more cookies later?
