These monster cookies are the classic oatmeal peanut butter cookies all dressed up for Christmas with red and green M&M’s, white chocolate chips and holiday sprinkles. A fun and festive treat for cookie exchanges and gift giving!
It’s Christmas cookie time again, and along with my stained glass cookies and spritz cookies, these Christmas monster cookies are on my must-make list every year.
You’ve heard of monster cookies, right? Those oatmeal-peanut butter-M&M-chocolate chip delights? This is a holiday version of the popular classic and I have to say, I like it even better than the original version.
How do you make monster cookies?
This is a pretty standard cookie dough with flour, two types of sugar, peanut butter and rolled oats. It’s the add-ins that make this recipe special. I’ve used holiday colored M&M’s and white chocolate chips to get these little guys ready for Christmas!
The cookie dough gets scooped out into balls and then topped with holiday sprinkles for another layer of festivity before they head to the oven. The end result is a soft and chewy cookie that’s packed with amazing flavors. You won’t be able to eat just one!
Tips for monster cookies
- For the prettiest cookies, press some extra M&M’s and white chocolate chips into the tops of the balls of dough before baking. It’s a bit of a tight fit with the sprinkles in the mix too, but it’s totally worth it for a beautiful end result.
- Not a fan of white chocolate chips? Feel free to substitute the more traditional semisweet chocolate chips.
- Use a cookie scoop or a tablespoon measure to make sure all of your cookies are the same size
- The cookie dough can be stored in the fridge for up to 3 days before baking. If you’re planning to make your dough ahead of time, you may want to omit the M&M’s and add them just before baking so that the color from the candies doesn’t stain the dough if it’s in the fridge for a while.
Can you freeze baked cookies?
These monster cookies are a great candidate for the freezer. Simply place the cookies in a single layer in a resealable bag, then freeze until solid. When you’re ready to eat your cookies, take the from the freezer and let them sit at room temperature until they’re soft.
These Christmas monster cookies are the perfect thing to take to a cookie exchange because they’re so unique. I also like to package them up in gift tins or cellophane bags to give to teachers, friends and family. Everyone who tries these cookies asks me for the recipe!

In the video it shows you added sprinkles to the cookie dough. The recipe says to press them into the ball of dough. Which is it? I plan on making them for Christmas gifts. They look awesome and super easy to make!
Thanks for catching that! They come out prettier if you press the tops in sprinkles but either way produces delicious cookies.
can you do the receipe without peanut butter
You’d have to substitute almond butter or sunflower butter which is nut free.
