If you’re someone who can’t get enough of soft sugar cookies during the holidays, you’re going to fall hard for these Christmas Cookie Bars. I’ve always loved the magic that comes from combining buttery vanilla dough with festive sprinkles, and this recipe captures that magic in a fuss-free bar form. No need to roll out dough or use cookie cutters—just spread, bake, frost, and slice. Simple, satisfying, and full of that holiday cheer.

What I especially love about these cookie bars is their soft, cakey center with the occasional crunch from sprinkles. The thick layer of sweet vanilla frosting on top seals the deal. Whether you’re baking for a cookie swap, holiday party, or just a cozy evening in with hot cocoa, these bars are always a hit. They’re easy enough for a beginner and impressive enough to share.

Why You’ll Love These Christmas Cookie Bars

These bars are everything you want in a holiday treat: rich, soft, and full of buttery vanilla flavor. You get the nostalgic taste of a classic sugar cookie, but in a much quicker and easier form. The red and green sprinkles throughout the dough and on the frosting instantly bring a festive touch, making these perfect for holiday gatherings or edible gifts.

What Kind of Sprinkles Work Best for Christmas Cookie Bars?

I recommend using jimmies or soft nonpareils for the best results. Jimmies hold up well in the dough without bleeding too much color, while nonpareils can give a little crunch if you’re into that. Avoid using large sanding sugar or hard candies inside the batter, as they can melt oddly or affect the texture.

Options for Substitutions

Need to switch things up? You absolutely can.

• Dairy-free: Use plant-based butter and a dairy-free milk alternative in the frosting.
• Gluten-free: Swap in your favorite 1:1 gluten-free flour blend.
• Flavor twist: Add a splash of almond extract or peppermint for a different spin.
• Frosting: Cream cheese frosting is a fantastic tangy alternative to the vanilla buttercream.

Step 1: Prepare Your Pan and Preheat the Oven

Preheat your oven to 350°F (175°C) and line a 9×13-inch baking pan with parchment paper, leaving a little overhang on the sides for easy removal.

Step 2: Cream the Butter and Sugar

In a large mixing bowl, use an electric mixer to cream the unsalted butter and granulated sugar together until the mixture is light and fluffy. This typically takes 2-3 minutes.

Step 3: Add the Eggs and Vanilla

Beat in the eggs one at a time, followed by the vanilla extract. Make sure everything is fully combined before moving on.

Step 4: Combine Dry Ingredients

In a separate bowl, whisk together the all-purpose flour, baking powder, and salt. Gradually add the dry ingredients to the wet mixture, mixing just until combined. Do not overmix.

Step 5: Fold in the Sprinkles

Gently fold in the Christmas-colored sprinkles with a spatula. Be careful not to over-stir so the colors don’t bleed.

Step 6: Spread the Dough Evenly

Transfer the dough into your prepared pan and spread it out evenly using a spatula or your hands. Try to make the top as smooth as possible for a clean finish.

Step 7: Bake the Bars

Place the pan in the preheated oven and bake for 22-26 minutes or until the edges are lightly golden and a toothpick inserted in the center comes out clean.

Step 8: Cool Completely

Remove the pan from the oven and allow the bars to cool completely in the pan. This step is important before frosting to avoid melting.

Step 9: Frost the Bars

Once cooled, spread a generous layer of buttercream frosting over the top using an offset spatula. Make it as thick or thin as you like.

Step 10: Add the Final Sprinkles and Slice

Top with additional sprinkles immediately after frosting. Slice into squares or rectangles, and your Christmas Cookie Bars are ready to serve!

How Long to Prepare the Christmas Cookie Bars

Prep Time: From start to oven-ready, the prep time takes about 15 minutes. This includes mixing the batter, folding in the sprinkles, and spreading everything evenly into your baking pan.

Baking Time & Cooling: The cookie bars bake for around 22–26 minutes. Cooling is essential and will take another 30–45 minutes before you can frost. Altogether, expect just over an hour from start to slice.

Tips for Perfect Christmas Cookie Bars

• Make sure the butter is softened, not melted, to get the right creamy texture when creaming with sugar.
• Don’t overmix the batter after adding the flour—this keeps the bars soft and fluffy.
• Use parchment paper to lift the bars out easily for clean slicing.
• Let bars cool completely before frosting to avoid a runny mess.
• For cleaner cuts, chill the frosted bars slightly before slicing.

Watch Out for These Mistakes While Cooking

• Overbaking: Even a few extra minutes can dry out the bars. Remove when the edges are golden, but the center is just set.
• Using the wrong sprinkles: Nonpareils can bleed if overmixed. Stick to jimmies for baking.
• Skipping the salt: It may seem minor, but a pinch of salt enhances all the other flavors.
• Not leveling the batter: Uneven batter means uneven baking. Take time to smooth it out.
• Frosting too soon: Warm bars will melt your buttercream into a mess.
