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.
Then once done, slice and serve up a delicious cookie bar that takes no time to make.
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.
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.
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.

Hi , I’m on cloud nine with all these wonderful recipes !!!! I have tried so many can’t wait to try these . You have the best selection nothing hard just Delicious. Keep up the good work. Thanks
hi, what type of flour is used here please? thanks
all-purpose flour
these cookies look yummy 😋😋
can I use salted butter? if so, do I omit salt.
Yes, you can use salted butter. I would cut the added salt to 1/2 teaspoon in that case.
Can we use less sugar, brown and reg sugar
Using less sugar would change the texture and taste of the bars. I do not recommend it.
I tried these twice because the first time they came out awful and salty. I tried again with less salt and unsalted butter and they still came out too gooey and salty. I did everything the recipe said and they just taste horrible. Something is up with this recipe. Maybe a typo or something. I won’t make it again.
I am sorry that you did not enjoy these cookie bars. They are soft and gooey by nature but they should not taste salty. How much salt did you use? You said they tasted horrible- what did they taste like aside from salty? I would like to help troubleshoot what went wrong.
