Christmas Monster Cookies for your December weekend baking…festive, easy, and sweet. Homemade chocolate chip cookies, made with oats, pretzels pieces, plenty of chocolate chunks, white chocolate, and plenty of holiday M&M’s. There’s nothing not to love about these sweet chocolate (crunch) cookies. Each bite is slightly crisp on the edges but soft and gooey in the center…with just a little salty pretzel crunch and milk chocolate throughout.
Fridays in December are just better! There are holiday parties, searching for the perfect gift for someone you love, and baking the nights away with family and friends. Well, at least that’s the “Hallmark” version I have in my head.
The reality is a little less picture-perfect for sure, but I’m definitely doing the baking! It’s one of the reasons we love this season the most. I mean there are so many cookies! As I said on Tuesday, this year I’m really focusing on all of the holiday cookies I haven’t made before.
My list of cookies is a mile long, but I only have a handful of days to share them. So, I’m trying to pick the very best on my list. It’s tricky, but I always knew these cookies needed to be shared. The combination of ingredients is just too good.
The steps are easy
One: gather your ingredients. You’ll need the basics…butter, sugar, flour, etc. Simple, simple, nothing fancy, but all good.
Two: the stir-ins, they’re are the most important part. You’ll need old fashioned oats, salted pretzel twists, semi-sweet or dark chocolate chunks, and white chocolate chips. And then plenty of red and green holiday M&M’s, which really make these cookies.
Three: beat, mix, stir, bake.
Four: eat these cookies warm, just out of the oven, because these are those kind of gooey delicious cookies.
A couple notes
It’s important to note that these cookies do spread. They’re meant to have slightly crisp edges and perfectly soft gooey centers, just like in the photos. My favorite type of cookie…totally delicious.
If you want a bit of a thicker cookie, simply omit the additional egg yolk and use only two eggs. This will give you a thicker cookie without as much spreading.
To get the M&M’s to really pop, I like to add in a few just before the cookies finish baking completely. This way each cookie has a bit of the festive M&M’s right on top.
What I love about these cookies is that they’re so easy to make. They require no chilling and they really are completely no fuss. Especially when it comes to Christmas cookies.
These cookies have perfectly crisp edges, yet soft and gooey centers. They’ve got a nice crunch plus a little saltiness from the pretzels – the best kind of cookie.
I’m excited to include these in the year’s Christmas cookie box. They’re perfect for packing up and gifting to friends for the holidays!

great recipe! I have made these a few times, not always with the same chocolate and/or candy pieces but always delicious! Yesterday, I did not feel like taking the time for cookies so I did a free form…simply spread the dough on parchment on a sheet pan.
Hi Lauren,
Happy Friday!! Thanks a lot for giving this recipe a go, I love to hear that it was enjoyed! xxTieghan
These cookies are soooooo good!!! I love all the different textures and flavors. The pretzels in particular are such a fun addition. I knew they would be good because I also love your salted caramel pretzel snickerdoodles, but I think these monster cookies are even better.
Hi Erica,
Awesome!! Thanks a bunch for trying this recipe out, I love to hear that it was a winner! xTieghan
Made these last night and they are delicious! I had to add peanut butter because it is one of my favorite parts of monster cookies and since we are past Christmas, I used dark chocolate M&M’s. The crushed pretzels were a great addition, not going to lie, I was a little hesitant about adding them. Overall, awesome monster cookie recipe, will keep this one in the rotation!
Hi Erin,
I really appreciate you giving the recipe a try, so glad to hear that it was enjoyed! Have a great week! xxT
I ran out of time at Christmas to make these, but I still had the m and ms waiting! Made these for after school snack and they were a hit. Everyone loves the oats and pretzels in it and I agree, definitely great additions. I appreciate any recipe that uses dark brown sugar! A great cookie for when you’re looking for something a little unexpected!
Hi Michelle,
Thanks so much for giving this recipe a try, I love to hear that it was enjoyed! xTieghan
Made these Christmas Eve. They’re a lot of work just for cookies tbh. I prefer to stick to a simpler cookie in the future but it’s always fun trying out new recipes. I think it would have been better to just sprinkle them with flaky sea salt instead of pretzels since there is already so much going on in the cookie. This recipe is very versatile to whatever you want to put in them though so you can get creative.
Hi Sammi,
Thanks for giving the recipe a try, I have to disagree, I really don’t think this recipe could get any easier. Let me know if I can help in anyway for next time! xTieghan
