We are skipping the chilled dough, the rolling pin frustration, and the endless decorating marathon!

Why You Will Love These Soft Christmas Sugar Cookie Bars

If you’re anything like me, the holiday baking list is long, but the patience for cutting tiny shapes is definitely not! That’s why these bars are my secret weapon for Christmas party food. Here are just a few reasons why this recipe replaces traditional cut-outs for me every year:

• One Pan Wonder: Everything happens in a single 9×13 pan. Cleanup is a dream, which is huge during busy holidays!
• Incredibly Soft Texture: No hard or dry edges here. These bars are designed to be thick, chewy, and soft, just like your favorite holiday cookie.
• Maximum Flavor, Minimum Effort: You get that classic, buttery sugar cookie taste we all adore, but without the fussy cutting and re-rolling of dough scraps.
• Perfect for Cookie Exchanges: They travel beautifully because they stay intact. Just take the whole sheet, trim them into squares, and go!
• Kid Friendly Holiday Baking: Getting the kids involved is so much easier! They can help press the dough in, and everyone loves dumping the sprinkles everywhere.

Essential Ingredients for Perfect Christmas Sugar Cookie Bars

The secret to getting that incredible, buttery texture we’re aiming for is starting with excellent, room-temperature ingredients. You don’t need anything fancy here, just reliably good basics. Remember, we want these to taste like the best, thickest sugar cookie you’ve ever had, just in bar form!

Here is exactly what you need to gather up before you start mixing:

• 1 cup unsalted butter, softened
• 1 1/2 cups granulated sugar
• 2 large eggs
• 1 tablespoon vanilla extract
• 3 cups all-purpose flour
• 1 teaspoon baking powder
• 1/2 teaspoon salt
• 1/2 cup milk
• For the Frosting: 4 cups powdered sugar, 1/2 cup unsalted butter (softened), 1 teaspoon vanilla extract, 3-4 tablespoons milk
• Holiday sprinkles for decoration

Ingredient Notes and Substitutions for Your Christmas Sugar Cookie Bars

A few quick notes that make a huge difference to your final **Holiday Baking Ideas**. First, please make sure your butter for both the dough and the frosting is truly softened—not melted! Softened butter creates the air pockets we need for that wonderfully soft baked bars texture.

Also, don’t skimp on the vanilla extract. Since this is essentially a sugar cookie base, the vanilla needs to shine through. Use the good quality stuff you keep for special occasions. It makes a noticeable difference!

Finally, when measuring flour, don’t just scoop it out of the bag with your measuring cup. That packs it in, and you’ll end up with dry bars. Spoon the flour lightly into the cup and then level it off. Small steps, huge payoffs!

Step-by-Step Instructions for Easy Christmas Sugar Cookie Bars

This is where the magic happens! Making these fantastic Christmas Sugar Cookie Bars is surprisingly straightforward, even though the result looks like you spent hours in the kitchen. Just follow these steps closely, and you’ll have a gorgeous, frosted pan of holiday cheer ready in under an hour of active time.

Preparing the Dough for Your One Pan Cookie Recipe

First things first, always preheat your oven to 350°F (175°C). You want to line your 9×13 inch pan with parchment paper, making sure you leave that handy overhang on the sides—that’s our built-in handle for lifting the whole slab out later. In your big mixing bowl, cream the softened butter and sugar together until it looks pale and fluffy. This takes a minute or two, but it’s important! Then, beat in those two eggs, one at a time, followed by the vanilla.

In a separate bowl, quickly whisk your flour, baking powder, and salt together. Now, here comes the crucial part for soft bars: slowly add the dry mix into the wet, alternating with the milk. Mix on low speed, or by hand, until it’s *just* combined. Seriously, stop mixing the second you see no more streaks of flour. Overmixing is how you get tough cookies!

Baking and Cooling Your Christmas Sugar Cookie Bars

Once your dough is ready, press it evenly into that prepared pan. Try to keep the thickness level so it bakes evenly across the whole cookie base. Bake this beauty for about 20 to 25 minutes. You are looking for nice, light golden edges, but the center should still look just a tiny bit soft, maybe a little underbaked.

Don’t be tempted to frost them yet! This waiting game is the hardest part, but absolutely essential. You must let the bars cool completely in the pan on a wire rack. If you try to spread frosting on warm bars, you’ll end up with a melted, runny mess instead of beautiful, thick frosting.

Making the Vanilla Buttercream Topping for Festive Frosted Treats

While those bars are chilling out, whip up the frosting! You’ll want the softened butter smooth first. Then, start adding your powdered sugar slowly, along with the vanilla and about 3 tablespoons of milk. Keep beating until it looks smooth and spreadable. If it seems too stiff—and remember, we want a thick layer!—add that fourth tablespoon of milk until it’s perfect.

When the bars are stone cold, just spread that creamy topping right over the top. Immediately follow up with a giant handful of your best holiday sprinkles so they stick perfectly. Then, let that frosting set just a little before you slice them into squares.

Tips for Success When Making Christmas Sugar Cookie Bars

Listen, Kate here—I want you to have zero baking disappointment this December! The absolute key to mastering these Christmas Sugar Cookie Bars is baking them just shy of being done. Pull them out when the center looks a little soft; they continue cooking as they cool on the rack. Seriously, don’t overbake them if you want that perfect melt-in-your-mouth feeling.

Also, that cooling time I mentioned earlier? Non-negotiable! You have to let them cool completely before that vanilla buttercream goes on top. If you’re in a rush, you can prep the base a day ahead and wrap it up tightly at room temperature. Nothing beats a simple holiday treat that tastes this incredible, and you can check out more great baking tips over at Yummy Dished!

Make Ahead Christmas Desserts: Storing Your Christmas Sugar Cookie Bars

One of the best parts about these cookie bars is how fantastic they are for planning ahead. During the holidays, anything I can tackle early is a huge win, right? You absolutely have the option to make these ahead, which makes them perfect for your list of Make Ahead Christmas Desserts.

If you baked the base but haven’t frosted them yet, just wrap that entire cooled slab tightly in plastic wrap—and maybe even foil over the wrap for extra protection. You can safely store the uncoated cookie base at room temperature for up to two days. It stays fantastically soft!

Now, once they are frosted and already cut into squares? That’s slightly different. Since we used a classic buttercream frosting containing butter, I keep them stored in an airtight container at cool room temperature for about two days. If your kitchen is warm, or if you need them to last longer, popping them into the fridge is fine! You might need to let them sit out on the counter for about 30 minutes before serving to take the chill off and bring back that soft texture we worked so hard for.

I usually avoid reheating these entirely, as even a quick microwave burst can sometimes melt the pretty sprinkles or turn the texture grainy. Serving them slightly cool or brought back to room temperature is always the best bet for these festive frosted treats!

Serving Suggestions for Your Festive Frosted Treats

Okay, so you have this giant, gorgeous pan of deliciousness. Now, how do we present these show-stopping Christmas Sugar Cookie Bars? Presentation is half the fun during the holidays, especially when you’re aiming for great Christmas Party Food!

The easiest way is to just leave them frosted and uncut on a large, festive platter. When people start grazing, they can grab a knife and cut their own squares—it feels totally communal and fun. I like to scatter a few extra colorful sprinkles around the plate *after* I cut them, just to make the whole platter pop!

When it comes to drinks, these bars pair perfectly with something warm to balance out the sweetness. They are incredible dunked—just a tiny bit!—into a mug of my favorite hot cocoa mix. They also go beautifully alongside coffee or even a nice cold glass of milk, making them a hit with every age group.

If you’re building a full dessert table, use these bars as the centerpiece! Because they’re so colorful, they don’t need much else on their platter. They stand tall all on their own as the ultimate simple holiday sweet.

Frequently Asked Questions About Christmas Sugar Cookie Bars

It happens! When you dive into a new recipe, especially a seasonal favorite like these great Easy Cookie Bars, questions always pop up. I’ve gathered the ones I get asked most often about achieving that perfect texture and stunning look. Hopefully, these quick tips help you nail it on your first try!

Can I use cookie cutters on this Christmas Sugar Cookie Bar dough?

That’s a great question! I designed this recipe specifically because rolling and cutting traditional sugar cookies can be a total time-suck around the holidays. Because the dough is intentionally softer and has more fat to keep it moist, it gets really sticky and messy if you try to cut it right out of the mixer. You *can* do it, but only if you chill that dough for at least two hours—or better yet, overnight—before trying to work with cookie cutters. For the quickest results, stick to the bar format!

What is the best way to get a smooth top on my Christmas Sugar Cookie Bars?

Achieving that professional, smooth layer of frosting on your Decorated Holiday Bars is all about temperature control! You have to be patient and let that cookie base cool down completely. I mean it—room temperature, not even slightly warm. Once it’s cold, use an offset spatula. You know, that one with the bent little handle? That tool is your best friend here. It lets you glide the buttercream over the top without your hand touching the icing, giving you a beautifully flat, glossy surface, even before you get to the sprinkles!

My bars seem a little too soft in the middle—did I underbake them?

If you pulled them out when the edges were golden but the center looked a tiny bit soft, congratulations! You followed my best advice perfectly. That slight under-baking is exactly what ensures these bars stay soft and chewy rather than turning into crunchy squares later on. They firm up quite a bit as they cool on the wire rack. Unless you see wet, liquid batter on a toothpick, they are done. They’ll set up perfectly as they rest!

Can I use a different type of frosting or just a glaze on these bars?

Absolutely! While I absolutely love the thick, creamy vanilla buttercream for these holiday treats, a simple powdered sugar glaze works well too if you prefer something lighter. If you opt for a glaze, just remember it hardens more firmly than the buttery frosting, so you’ll want to slice the bars before that glaze fully sets up.
