Christmas Cookie Bars

Christmas M&M cookie bars are a great way to serve up a crowd, without manning the oven making batches of cookies. Just whip up these Christmas cookies and get them baking.

What is a bar cookie?

Cookie bars are just like a cookie but baked in an 8×8 or 9×13 pan. Most cookie bars are great for serving up a crowd, potluck desserts, and more. Simple prep, easy bake, and you are able to slice and serve fast.

It is a great way to serve a handful of people without making actual cookies.

Christmas Chocolate Chip Cookie Bars

How to Make

Mix Batter | In a bowl or stand mixer, mix to combine your wet ingredients. Then whisk your dry ingredients together and slowly mix into the dry.

Candies | Fold in your M&Ms, sprinkles, and chocolate chips. Transfer dough to prepared baking dish.

More Candy | Top with remaining candies and gently press them down in the pan.

Bake | Bake your bars for 20-25 minutes or until the edges are light brown and fully cooked.

Cool and Slice | Once done, remove and allow to cool a bit. Then slice and serve up these moist, delicious cookie bars.

How do you know when cookie bars are done?

You know cookie bars are done when you take a toothpick and stick in the center and it comes out free of cookie batter. You will also see the edges pull away a bit from the sides of the pan. And the bars will create a golden brown color on top.

Best Way To Store Cookie Bars

You can store these holiday cookie bars in an airtight container at room temperature. They will stay moist for a few days, and then begin to dry out a bit.

If you don’t plan to eat them right away, then place in a freezer bag or container and freeze for 2-3 months. Thaw on the counter for a quick thaw when you get a craving for something sweet.

Holiday Cookie Bars

Best Sprinkles To Use

What I love about these cookie holiday bars are the colorful sprinkles. Feel free to use any sprinkles you have on hand. I find that Jimmies are a great sprinkle that holds shape and bakes up nicely. Sugar sprinkles that are colored sugar are not a good option as they will melt and break down as the cookies bake up.

Will cookies harden as they cool?

Like a classic cookie, these chocolate chip cookie bars will harden a bit once it is removed from the oven. The pan is hot so it will essentially still cook the bars a bit. Overall if you prefer softer bars, remove them from the oven a little early so they stay soft.

  1. My daughter and I absolutely love these. We will eat an entire pan in 3-4 days lol. Bad I know but it’s literally 3-4 pans in the course of November to December and we don’t do it again till the next year.
    The only thing I have noticed is I have to back about 5-10 minutes longer than the recipe but that might be because of environmental factors.
    All I know is they are fabulous. Thank you

    1. Ha! I can totally relate. We go through a whole pan of the yummy bars quickly as well. Thank you so much for taking the time to come back and leave a review/comment. I truly appreciate it! Merry Christmas to you and your family!

  2. 1 star
    I baked for 25 minutes at 350 with parchment paper and they are still gooey and raw. So disappointed as I was making for a party and now don’t have time to make anything else.

    1. It sounds like the bars just needed to be baked a few more minutes. You may want to check the temperature of your oven to make sure that it is accurate.

  3. Definitely baking time for this recipe is far from accurate!!!!! Baked for the full 25 minutes and pan was nearly only half baked!
    I should’ve known better – there is no way at the thickness of the batter in the pan that it bakes fully in 25 minutes.
    What I ended up doing is mixing it up into a crumble and re-baked for additional time. Now I have a brand new recipe called Christmas Cookie Crumble.
    This recipe tastes good, but I would recommend not following the baking particulars.

  4. 4 stars
    Very rarely a recipe works out exactly as instructed or pictured, but these came out amazing! made me feel like I could bake! very tasty and tender! Hubs is taking them to a work potluck today! Thanks for sharing your recipe!
