Christmas Sugar Cookie Bars
There's something magical about gathering around platters of soft, buttery Christmas Sugar Cookie Bars, especially when they're topped with a swirl of snowy vanilla buttercream and a burst of festive sprinkles. Home cooks love them for their simplicity and crowd-pleasing charm-they're perfect for holiday parties, last-minute cookie exchanges, or leaving out for Santa (along with a glass of milk, of course). Unlike finicky cut-out cookies, these bars stay tender and sliceable, making them a foolproof favorite. The scent of vanilla and warm sugar filling your kitchen? That's the real reason this recipe is a keeper.
What Makes This Recipe Special
- The dough is enriched with both butter and cream cheese, creating an unusually tender and moist bar that stays fresh longer than standard sugar cookies.
- A two-stage frosting-rich buttercream folded with soft cream cheese-delivers a silky, spreadable texture that clings beautifully to the bars without sliding off.
- The recipe cleverly uses salted butter in both the dough and frosting, balancing sweetness naturally and cutting down on added salt.
- Folding sprinkles directly into the dough ensures bursts of color in every bite, while a final sprinkle on top creates a festive, bakery-style finish.

Instructions
1
Preheat oven to 350°F (177°C). Line a 9 x 9-inch baking pan with parchment paper, allowing overhang for easy removal.
2
In a large bowl, cream together 1/2 cup softened salted butter and 1 cup granulated sugar until pale and fluffy. Beat in 1 large egg and 1 teaspoon vanilla extract until fully incorporated.
3
Gradually mix in 2 cups all-purpose flour and 1 teaspoon baking powder to the wet mixture until a thick dough forms. Gently fold in 1/4 cup festive sprinkles.
4
Evenly press dough into the prepared baking pan. Bake in preheated oven for 20 minutes or until golden at the edges and set in the center.
5
Remove pan from oven. Allow bars to cool completely in the pan. Using the parchment paper overhang, carefully lift bars out of the pan and transfer to a work surface.
6
Beat together 2 cups powdered sugar, 1/2 cup softened salted butter, 3 tablespoons softened cream cheese, 1 teaspoon vanilla extract, and 2 tablespoons milk until smooth and spreadable.
7
Generously spread frosting over the cooled cookie bars. Sprinkle additional festive sprinkles evenly over the surface.
8
Cut into squares with a sharp knife and serve immediately, or allow frosting to set for a firmer texture.
Essential Tips
Chill dough lightly
If your kitchen is warm, pop the dough into the fridge for 10-15 minutes after pressing it into the pan. This prevents spreading and helps the bars hold their shape during baking.
Press evenly
Use a flat-bottomed glass or offset spatula to press the dough into the corners of the pan. This ensures even baking and clean cuts later.
Cool completely
Letting the bars cool fully before frosting is critical. Warm bars will melt the buttercream and create a soggy mess-patience pays off!
Frosting consistency
If the frosting seems too thick, add milk ½ teaspoon at a time. It should glide smoothly over the bars but still hold its shape when spread.
Sharp knife trick
Dip your knife in hot water and wipe dry between cuts for clean, crumb-free edges. This is especially helpful if the bars are slightly chilled.
Smart Swaps & Variations
Peppermint Twist
Fold ¼ teaspoon peppermint extract into the frosting and top with crushed candy canes instead of sprinkles for a refreshing holiday flavor.
Brown Butter Bars
Brown the butter for the dough until nutty and golden-this adds a caramelized depth that pairs beautifully with vanilla cream-cheese frosting.
Gluten-Free
Swap all-purpose flour for a 1:1 gluten-free baking flour blend and use gluten-free sprinkles to keep the festive look (check labels for additives).
Citrus Zing
Add 1 teaspoon lemon or orange zest to the dough and top with white chocolate sprinkles for a bright, citrusy twist on classic holiday flavors.
What to Serve With This
- Warm mulled cider or spiced hot chocolate for a cozy December gathering.
- A scoop of vanilla ice cream or a dollop of whipped cream for a decadent dessert pairing.
- Mini candy canes or chocolate-covered espresso beans as edible garnishes around the platter.
- Mini cookies or shortbread alongside for a mixed holiday cookie plate.
Storage & Reheating
Storage
Store bars in an airtight container at room temperature for up to 5 days. They'll stay soft and fresh longer if you place a piece of parchment directly over the top to prevent drying.
Reheating
For a just-baked texture, warm bars in a 300°F (150°C) oven for 5-7 minutes before serving. Avoid microwaving, as it can make the frosting greasy and the bars tough.
Expert Chef Tips
- Use a kitchen scale to measure your flour for accuracy-fluctuations in flour volume can lead to denser or cakey bars.
- For a bakery-style sheen on the frosting, add ½ teaspoon light corn syrup to the buttercream mixture before spreading.
- If you're short on time, make the dough ahead and refrigerate it overnight. Press it into the pan and bake straight from the fridge-no need to warm it up first.

Frequently Asked Questions
Can I use unsalted butter instead of salted?
Yes, but add ¼ teaspoon fine sea salt to both the dough and frosting to balance the sweetness. Taste the dough before baking to ensure it tastes right-you can adjust salt level to preference.
Why are my bars spreading too much?
This usually happens if the dough is too warm or the butter was over-creamed. Chill the dough for 15 minutes before pressing it into the pan, and avoid overmixing the butter and sugar initially.
Can I make these bars ahead of time?
Absolutely! Bake and cool the bars, then frost and sprinkle just before serving. Store unfrosted bars in the pan covered at room temperature for up to 3 days, or freeze unfrosted bars for up to 1 month.
What's the best way to cut clean squares?
Use a sharp chef's knife or a pizza cutter. For extra precision, score the bars lightly with a knife before chilling them for 30 minutes-this helps prevent tearing when you make the final cuts.
Can I freeze the dough?
Yes! Shape the dough into a log, wrap it tightly in plastic, and freeze for up to 3 months. Thaw in the fridge overnight, then press into the pan and bake as directed.
How do I prevent sprinkles from bleeding into the frosting?
Press a thin layer of frosting onto the bars first, let it set for 10 minutes, then add the remaining frosting and sprinkles. This creates a barrier that keeps colors vibrant.
Can I use a different size pan?
For a thinner bar, use a 9x13-inch pan and reduce baking time to 15-18 minutes. For a thicker bar, use an 8x8-inch pan and bake for 22-25 minutes. Adjust frosting quantities proportionally.
Why does my frosting look grainy?
Graininess usually means the powdered sugar wasn't sifted or the butter wasn't fully softened. Sift your powdered sugar and ensure both the butter and cream cheese are at room temperature before mixing.
