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, so be careful when cooking the cookie dough! 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, my trick is 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!
