Why These Ultimate Chewy Christmas Cookie Bars Are Your New Holiday Favorite
Honestly, these bars beat out almost every other holiday sweet in my book. They cover everything you desperately want when you’re doing Festive holiday baking: maximum payoff for minimum effort. You get all the rich flavor of your favorite chocolate chip cookie, just baked flat. Plus, these Christmas cookie bars are incredibly durable for transport, which makes them perfect for sharing!
- They nail that perfect texture we all crave. Forget dry edges; these are thick, soft, and wonderfully chewy Chewy Christmas squares.
- The M&M’s and chocolate chips create the most beautiful, colorful, festive look right on top. You can see how pretty they are on sites like this one!
- They are so easy to handle! No fussy frosting needed; these are true cut and serve Christmas cookies that look amazing stacked on a platter.
Perfect Texture: Soft, Chewy, and Gooey Christmas Treats
The secret to getting those dense, satisfyingly chewy squares lies almost entirely in how we handle the sugar and fat upfront. When you use both granulated and brown sugar, that molasses in the brown sugar locks in moisture and creates that signature chewiness. We’re aiming for that incredible “just-set” center that practically melts in your mouth. They absolutely qualify as Gooey Christmas treats, especially if you follow my baking advice later on!
Simple Assembly for Easy Christmas Dessert Bars
If you despise washing ten different bowls, you’ll love this. Everything mixes right into the same pan, making these some of the best Easy Christmas dessert bars out there. We skip the rolling, the cutting out shapes, and the fiddly decorating that takes up half your day. Once they are baked, you just lift the whole thing out onto a cutting board. This one-pan method is a lifesaver when you’re trying to get dinner on the table *and* have dessert ready for guests.
Gathering Ingredients for Your Christmas Cookie Bars
Okay, let’s talk about what you need to grab. For these Christmas cookie bars, we are keeping the ingredient list straightforward so you aren’t running to three different specialty stores. Everything here should be easy to find on your weekly grocery run. Getting the right things—like that soft butter—is key for the base texture, so make sure your dairy is ready!
Here is exactly what I use to get 24 of the best bars you’ll ever taste:
- 1 cup unsalted butter, softened (This needs to be soft, not melted, remember!)
- 1 cup granulated sugar
- 1/2 cup packed light brown sugar (Packed tightly into the measuring cup is important here)
- 2 large eggs
- 1 teaspoon vanilla extract
- 2 1/4 cups all-purpose flour
- 1 teaspoon baking soda
- 1/2 teaspoon salt
- 1 1/2 cups M&M’s Holiday Baking Candies (Use the festive red and green ones, of course!)
- 1 cup semi-sweet chocolate chips
- 1/2 cup white chocolate chips
See? Simple! We build that amazing, rich cookie flavor first, then we load it up with those colorful, festive mix-ins. Having the right types of chocolate chips—semi-sweet and white—gives us such a great contrast in flavor when you bite into these festive holiday baking squares.
Step-by-Step Guide to Making Perfect Christmas Cookie Bars
Watch how quickly this magical dough comes together! We want to keep things moving so the butter doesn’t get too warm, but we also need to be patient where it counts, like when creaming the sugars. This recipe is really forgiving, which is why it’s one of my absolute favorites for Christmas cookie bars. I’ve got my classic cookie method that uses a similar creaming technique, and it always pays off!
Preparing the Pan and Creaming the Fats and Sugars
First things first: get that oven preheating to 350°F (175°C). Now, grab your 9×13 inch pan and line it with parchment paper. This is a huge tip for all bar recipes! Make sure you leave an overhang on two sides—that’s your handle for lifting the whole pan out later. Lightly grease that paper, too, just to be safe. In your big bowl, it’s time to cream the butter, granulated sugar, and brown sugar together until it looks fluffy and pale. This step is non-negotiable for texture!
Mixing the Dough and Folding in the Festive Mix-ins
Next, beat in your eggs one by one, followed by that splash of vanilla. In a separate bowl, quickly whisk your flour, baking soda, and salt—just getting them acquainted. Now, add those dry ingredients to your wet mixture slowly. Listen to me: Mix only until you see no more dry streaks of flour. Seriously, stop mixing! Overdeveloping the gluten here is what turns chewy squares into sad, tough biscuits. Finally, fold in all your goodies: the M&M’s, semi-sweet, and white chocolate chips. Be gentle!
Baking and Cooling Your Christmas Cookie Bars
Scrape that beautiful dough smoothly into your prepared pan. It’s time to bake for 20 to 25 minutes. Here’s where we ensure they are wonderfully gooey Christmas treats: pull them out when the edges look lightly golden but the center still seems just a tiny bit soft. They stiffen up a lot while cooling! This slight underbake is the secret sauce. Once out, they must cool completely in that pan—I usually wait a good hour or two—before you use those parchment handles to lift them out for cutting. It’s worth the wait, I promise you’ll see links to great ideas on this recipe site for inspiration!
Tips for Success with These Festive Holiday Baking Treats
I want you to feel confident when you tackle these christmas cookie bars, and a few little tricks make all the difference. Remember when I mentioned slightly underbaking? That continues to be my number one suggestion for achieving those intensely chewy centers. Don’t be afraid to pull them when the middle still looks a touch soft!
Another important thing for great Simple holiday baking ideas is your ingredients. Make sure those two large eggs are at room temperature before adding them to the creamed butter mixture. Room temperature eggs emulsify so much better, giving your bars a smoother, more uniform structure right from the start.
If you decide you want a little something extra on top, go for a simple vanilla glaze or even a cream cheese frosting once the bars are totally cool. They taste fantastic plain, but a little drizzle of white frosting makes them look extra special for your holiday gatherings. These little details elevate them into the best Christmas party treats!
Variations on Christmas Cookie Bars: Beyond M&Ms
While I absolutely adore these M&M ones—they’re so bright and fun—I know sometimes you want to twist up the flavor profile a bit, right? It’s the holidays, after all; we can change things up! These Christmas cookie bars are based on a classic chewy cookie dough, which means they are super versatile. You can still make them easy but give them a completely different seasonal twist.
If you’re looking for something a little more sophisticated than candy-coated chocolate, try tossing in some crushed candy canes or a teaspoon of peppermint extract right when you mix in the vanilla. That immediately sends these straight into classic holiday territory. You can even look at recipes for straightforward Christmas Sugar Cookie Bars for Christmas if you prefer a cleaner, buttery base that you can frost later.
Trying Holiday Layered Cookie Bars or No Bake Christmas Cookie Bars
Sometimes texture is everything, and if you’re not feeling the familiar cookie dough base, there are other amazing options out there for festive holiday baking. You might want to explore recipes for Holiday layered cookie bars, which often involve a buttery crust topped with sweetened condensed milk, coconut, and chocolate chips—a decadent choice!
Then there are the brilliant No bake Christmas cookie bars for those days when you just can’t bear to turn the oven on. These are usually chilled until firm, which means zero baking time. They often rely on a graham cracker base and can be loaded up with holiday marshmallows and white chocolate. But let me tell you, for pure, satisfying chewiness that holds up well for a cookie exchange, nothing beats this baked M&M version we made above!
If you like the concept of simple, unfrosted-but-still-fancy cut and serve Christmas cookies, I have a great basic dough recipe here that you could easily adapt for bar form by just adding your favorite holiday mix-ins directly into the dough!
Serving and Storing Your Christmas Cookie Bars for Parties
The final hurdle in holiday baking is getting everything to the party looking perfect! Since these are such sturdy Christmas party treats, getting them there is half the battle. Make sure they are completely cool—and I mean completely cool—before you even think about slicing them beyond the initial score marks. Slicing too early is the quickest way to turn your beautiful squares into a gooey puddle! If you are interested in the layered style, some wonderful presentation ideas for those can be found here.
For storing, an airtight container is your best friend. They store beautifully at room temperature for up to four or five days because of that good fat content keeping them soft. I like to place wax paper or parchment between the layers so the chocolate chips don’t stick to the layer above them. When it comes to serving, they go perfectly with a hot mug of apple cider or maybe even one of my favorite holiday simple holiday drinks on the side. Enjoy seeing everyone grab for these first!
Frequently Asked Questions About Our Christmas Cookie Bar Recipes
I find that when readers have just a couple of quick questions, they feel so much more confident diving into a new recipe. These Christmas cookie bars are easy, but sometimes the details trip people up, especially around the busy holidays. Let’s clear up the last few things so you can feel ready to bake!
Can I make these Christmas cookie bars ahead of time?
Yes, absolutely! That’s one of the best things about making cut and serve Christmas cookies like these. They actually taste even better the next day once the moisture settles down and the flavors really marry up. You can safely make them two days ahead of time. Store them layered with wax paper in an airtight container on the counter. They stand up really well to holiday travel, too, which makes planning so much easier!
How do I get the chewiest Christmas cookie bars possible?
If chewiness is what you are after—and trust me, you should be!—the trick is timing at the very end. When baking, you are aiming for that perfect middle ground. Pull them out of the 350°F oven right when the edges look set, but the very center still looks just a *little* shiny or soft, like underbaked dough. If you wait until it looks completely firm and dry, you’ve gone too far! They finish cooking slightly as they cool on the counter.
What is the best way to cut these bars cleanly?
This is where many people get frustrated, turning a beautiful pan of gooey Christmas treats into messy squares. The absolute best trick I learned is to wait until they are fully cooled—at least an hour or two! Then, take a large, sharp knife, dip it into a glass of hot water, and quickly wipe it dry. You use that warm blade to slice through the bar. Dip, wipe, slice, repeat. The heat melts the chocolate and keeps the dough from sticking or tearing, giving you those gorgeous, sharp edges perfect for a lovely display.

- Diet: Vegetarian
Ingredients
- 1 cup unsalted butter, softened
- 1 cup granulated sugar
- 1/2 cup packed light brown sugar
- 2 large eggs
- 1 teaspoon vanilla extract
- 2 1/4 cups all-purpose flour
- 1 teaspoon baking soda
- 1/2 teaspoon salt
- 1 1/2 cups M&M’s Holiday Baking Candies
- 1 cup semi-sweet chocolate chips
- 1/2 cup white chocolate chips
Instructions
- Preheat your oven to 350°F (175°C). Line a 9×13 inch baking pan with parchment paper, leaving an overhang on the sides for easy removal. Lightly grease the paper.
- In a large bowl, cream together the softened butter, granulated sugar, and brown sugar until the mixture is light and fluffy. You can use an electric mixer for this step.
- Beat in the eggs one at a time, mixing well after each addition. Stir in the vanilla extract.
- In a separate medium bowl, whisk together the flour, baking soda, and salt.
- Gradually add the dry ingredients to the wet ingredients, mixing on low speed until just combined. Do not overmix the dough.
- Gently fold in the M&M’s, semi-sweet chocolate chips, and white chocolate chips using a spatula.
- Press the cookie bar dough evenly into the prepared 9×13 inch pan.
- Bake for 20 to 25 minutes, or until the edges are lightly golden brown and the center is set. For extra gooey results, slightly underbake.
- Let the bars cool completely in the pan on a wire rack before lifting them out using the parchment paper overhang.
- Once cool, cut the bars into squares. You can frost them if desired, but they are great plain.
Notes
- For the chewiest bars, use slightly less baking time. The center should look mostly set but still soft.
- If you want a frosted look, use a simple vanilla glaze or cream cheese frosting after the bars have cooled completely.
- These bars are excellent for Christmas cookie exchanges because they hold their shape well when cut.
