Easy Christmas Tree Sugar Cookie Bars

Christmas Tree Sugar Cookie Bars are the kind of holiday dessert that brings baking and decorating together in one festive treat. Instead of rolling and cutting individual batches of sugar cookies, you bake soft, buttery cookie dough in one pan, let it cool, and transform the slab into adorable Christmas trees. A little green icing, colorful sprinkles, and creative decorating turn simple cookie bars into a centerpiece worthy of any holiday cookie tray.

These Christmas Tree Sugar Cookie Bars are especially fun for family baking days, Christmas parties, cookie exchanges, and edible homemade gifts. The dough is sturdy enough for cutting while remaining soft and satisfying to eat. Better yet, most of the preparation is straightforward, so you can spend more time decorating and less time managing complicated baking techniques.

Why You’ll Love These Christmas Tree Sugar Cookie Bars

There is something especially convenient about making Christmas cookies as bars. You get the buttery texture and festive appearance of decorated cookies without having to roll dough repeatedly or bake several trays.

Christmas Tree Sugar Cookie Bars also give you plenty of room for creativity. Decorate them traditionally with green icing and pearl sprinkles, or bring out several colors and let everyone design their own Christmas tree.

The recipe is also wonderfully approachable. The dough comes together using familiar baking ingredients, spreads into a standard 9-by-13-inch pan, and bakes in about 25 to 30 minutes.

Chilling the baked cookie slab before cutting is an important extra step. It firms the cookie enough to produce cleaner Christmas tree shapes without sacrificing its soft, chewy texture.

Ingredients for Festive Christmas Tree Cookie Bars

The original inspiration uses chocolate chips for extra sweetness and texture. If you prefer a more traditional sugar-cookie-style bar, they can be reduced or omitted. Either way, the buttery dough makes an excellent base for holiday decorating.

• Salted butter: Creates a rich, buttery flavor and helps give the cookie bars their soft texture.
• Brown sugar: Adds moisture, sweetness, and a subtle caramel note that keeps the bars pleasantly chewy.
• Granulated sugar: Provides classic cookie sweetness while helping create the right structure.
• Large eggs: Bind the ingredients and contribute moisture and richness.
• Vanilla extract: Gives the cookie dough its warm, familiar bakery-style aroma.
• All-purpose flour: Provides enough structure for the baked slab to hold its shape when cut into Christmas trees.
• Baking soda: Helps the dough rise slightly and prevents the finished bars from becoming overly dense.
• Kosher salt: Balances the sweetness and enhances the vanilla and buttery flavors.
• Cornstarch: Helps produce a softer, more tender cookie texture while maintaining enough stability for cutting.
• Semi-sweet chocolate chips: Add pockets of chocolate throughout the bars. Leave them out for Christmas Tree Sugar Cookie Bars with a more traditional sugar cookie flavor.
• Green decorating icing: Turns the cut cookie bars into instantly recognizable Christmas trees.
• Holiday sprinkles: Add ornaments, lights, garlands, and other colorful Christmas details.

Easy Ingredient Swaps

There are several ways to customize these festive sugar cookie bars without changing the basic method.

Unsalted butter works in place of salted butter. When using it, consider adding a little additional salt to the dough according to your taste.

For classic Christmas Tree Sugar Cookie Bars, omit the semi-sweet chocolate chips. White chocolate chips are another festive alternative, while mini chocolate chips create smaller chocolate pockets that can make cutting the trees easier.

You can also use homemade buttercream or royal icing instead of ready-made decorating icing. Royal icing provides crisp decorative details, while buttercream creates a softer, creamier finish.

For decorating, try nonpareils, sanding sugar, sugar pearls, star sprinkles, or small candy pieces. Just remember that very hard candies can make the bars more difficult to bite into.

How to Make Christmas Tree Sugar Cookie Bars

Making these Christmas Tree Sugar Cookie Bars involves three main stages: preparing the cookie dough, baking and chilling the slab, and cutting and decorating your Christmas trees.

1. Preheat the oven. Heat your oven to 350°F. Prepare a 9-by-13-inch baking pan so the cookie slab will be easy to remove after baking. Lining the pan with parchment paper can make lifting the cooled cookie out especially convenient.
2. Cream the butter. Place two sticks of room-temperature salted butter in the bowl of a stand mixer fitted with the paddle attachment. Beat for approximately 3 to 4 minutes. Properly creamed butter gives the dough a smoother, lighter texture.
3. Add the sugars. Mix in 1 cup brown sugar and 1/2 cup granulated sugar. Continue beating until the mixture looks smooth and there are no obvious clumps. Scrape down the sides and bottom of the mixing bowl as necessary.
4. Mix in the eggs and vanilla. Add 2 large eggs and 1 teaspoon vanilla extract. Mix for approximately another minute, stopping to scrape the bowl if needed.
5. Combine the dry ingredients. In a separate bowl, whisk together 2 1/2 cups all-purpose flour, 1 1/2 teaspoons baking soda, 1/2 teaspoon kosher salt, and 1 teaspoon cornstarch. Mixing these ingredients separately helps distribute the leavening evenly throughout the dough.
6. Finish the cookie dough. Gradually add the dry mixture to the wet ingredients. Mix briefly, for roughly 30 seconds or just until everything comes together. Avoid excessive mixing after adding the flour because overmixing can make cookie bars tougher.
7. Add the chocolate chips if desired. Fold in up to 2 cups semi-sweet chocolate chips with a spatula. For a traditional sugar cookie version, simply leave them out.
8. Spread the dough into the pan. Transfer the dough to your prepared 9-by-13-inch pan. Press and smooth it into an even layer, paying particular attention to the corners. Even thickness promotes consistent baking.
9. Bake the cookie bars. Bake for approximately 25 to 30 minutes. The exact baking time can vary by oven, so begin checking toward the lower end of the range. The center should look set rather than wet or raw.
10. Cool completely. Allow the cookie slab to cool before attempting to remove or cut it. Cutting warm bars can cause the Christmas tree shapes to crumble or bend.
11. Chill until firm. Once cooled, place the cookie slab in the freezer for approximately 20 to 30 minutes. This short chilling period is particularly helpful because it firms the baked cookie before cutting.
12. Cut the Christmas trees. Remove the chilled slab from the pan and place it on a flat cutting surface. Press a Christmas tree cookie cutter firmly through the cookie to create individual tree-shaped bars.
13. Decorate the trees. Pipe green decorating icing across each Christmas tree. Squiggled lines or sweeping rows create the appearance of evergreen branches without requiring advanced piping skills.
14. Add ornaments and finishing touches. Finish your Christmas Tree Sugar Cookie Bars with sprinkles, sugar pearls, edible stars, or contrasting icing. Allow the decorations to set before stacking or packaging the cookies.

Secrets to Perfect Christmas Tree Sugar Cookie Bars

The most important trick is to avoid cutting the cookie slab while it is warm. Freshly baked bars are soft and can easily break around the narrower sections of a Christmas tree cutter. Complete cooling followed by 20 to 30 minutes in the freezer produces much cleaner shapes.

Room-temperature butter also matters. Butter that is still very cold will not cream smoothly, while melted butter can change the structure and texture of the dough.

Once the flour has been added, mix only until the dough comes together. Overworking flour develops more gluten and can take the bars from tender and chewy to unnecessarily firm.

Try to spread the dough to a consistent thickness as well. Thin corners may become dry before a thicker center has finished baking.

Finally, don’t worry about making the icing perfect. Christmas tree cookies look charming with irregular branches, colorful ornaments, and different decorating patterns. They are an ideal holiday baking project for children precisely because perfection isn’t necessary.

Fun Ways to Decorate Christmas Tree Sugar Cookie Bars

Green icing is the natural starting point, but there are countless ways to personalize these Christmas cookies.

For a classic tree, pipe green icing from side to side and add small round sprinkles as ornaments. Finish with a yellow star sprinkle at the top.

For snowy Christmas Tree Sugar Cookie Bars, decorate the trees with green icing and drizzle a little white icing over the branches. White sanding sugar can create an extra snowy appearance.

A Christmas-lights variation is equally simple. Pipe a thin garland across each tree and add brightly colored sprinkles along the line to resemble miniature lights.

You could also create a winter-white version using white frosting, silver sugar pearls, and sparkling sanding sugar. It offers a more elegant look for holiday dessert platters.

For a decorating party, leave the trees undecorated and arrange small bowls of frosting, sprinkles, and candies on the table. Guests can turn dessert into a Christmas activity.

Serving Ideas for Christmas Tree Sugar Cookie Bars

Christmas Tree Sugar Cookie Bars fit naturally onto a holiday cookie platter alongside gingerbread cookies, shortbread, chocolate crinkle cookies, peppermint treats, and other Christmas desserts.

Serve them with hot chocolate for a cozy family movie night, or pair them with coffee and tea after Christmas dinner.

They are also well suited to cookie exchanges. Once the icing has completely set, arrange the decorated bars in a holiday tin with parchment paper between the layers.

For edible gifts, package individual trees in food-safe treat bags and tie them with festive ribbon. Because each bar is already shaped and decorated, they make charming homemade party favors for school celebrations and Christmas gatherings.

Creative Variations to Try

One of the best things about Christmas Tree Sugar Cookie Bars is how easily the basic recipe can be adapted.

Classic Sugar Cookie Christmas Trees

Leave out the chocolate chips for a simpler vanilla-forward cookie. This variation lets the buttery dough and colorful decorations take center stage.

White Chocolate Christmas Tree Bars

Replace semi-sweet chocolate chips with white chocolate chips. Their creamy sweetness works especially well with vanilla and gives the bars a snowy holiday feel.

Peppermint Holiday Cookie Bars

Add a small amount of peppermint flavoring to the icing rather than heavily flavoring the dough. Finish with finely crushed candy canes for a festive peppermint crunch.

Chocolate-Dipped Christmas Trees

After cutting the chilled bars, dip the bottom portion of each tree into melted chocolate. Let the chocolate set before piping the green decorations.

Mini Christmas Tree Cookie Bars

Use a smaller tree-shaped cutter to create bite-size treats. Smaller cookies work particularly well for dessert tables where guests may want to sample several sweets.

How to Store Christmas Tree Sugar Cookie Bars

For the best texture, place fully cooled and decorated Christmas Tree Sugar Cookie Bars in an airtight container. If you need multiple layers, separate them with parchment or wax paper to protect the decorations.

Make sure the icing has set completely before stacking. Otherwise, even beautiful decorations can smear or stick to the cookie above them.

The undecorated cookie slab can also be prepared ahead of time. Bake and cool it, cover it carefully, and decorate closer to serving. This approach is especially convenient when preparing several desserts for Christmas.

If you plan to freeze the cookies, freezing them before elaborate decorating is generally the easiest option. Protect them well from air and moisture, then thaw before adding fresh icing and sprinkles.

How to Get Clean Christmas Tree Shapes

Cookie cutters work beautifully with bar cookies, but the technique is slightly different from cutting raw rolled sugar cookie dough.

First, make sure the baked slab is completely cold. The recommended freezer rest makes a noticeable difference.

Next, place the cookie on a sturdy, flat surface. Position the cutter carefully so you can fit as many Christmas trees into the slab as possible. Alternating the direction of the trees may help reduce scraps.

Press the cutter straight down instead of rocking it aggressively from side to side. A firm downward motion gives you cleaner edges.

Don’t discard the leftover pieces between the Christmas Tree Sugar Cookie Bars. The scraps taste just as good as the perfectly shaped trees. Serve them over vanilla ice cream, crumble them into a holiday parfait, or keep them as the baker’s snack.

Make These Christmas Tree Sugar Cookie Bars a Holiday Tradition

Christmas baking doesn’t need to involve complicated pastry techniques to feel special. Christmas Tree Sugar Cookie Bars turn a simple pan of buttery cookie dough into a festive activity that family and friends can enjoy together.

The 9-by-13-inch method eliminates much of the repetitive work associated with traditional cutout cookies, while chilling the baked slab makes it sturdy enough to create attractive tree shapes. Green icing, holiday sprinkles, and a little imagination handle the rest.

Whether you prepare classic vanilla trees, keep the chocolate chips from the original inspiration, or experiment with white chocolate and peppermint, these Christmas Tree Sugar Cookie Bars offer an easy way to bring color, creativity, and homemade sweetness to the holiday season.

Why These Festive Cookie Bars Deserve a Spot on Your Christmas Table

Christmas Tree Sugar Cookie Bars combine everything that makes holiday baking memorable: buttery cookie flavor, a soft and chewy texture, colorful decorations, and plenty of opportunities to get creative. Baking the dough in one pan also makes this recipe more approachable than preparing multiple trays of traditional cutout sugar cookies.

The chilling step is especially useful because it helps the baked cookie slab become firm enough to cut into neat Christmas tree shapes. Once the trees are ready, green icing, festive sprinkles, sugar pearls, and edible decorations can transform every cookie into something unique.

Whether you’re filling a Christmas cookie platter, planning a holiday baking afternoon with the family, or preparing homemade edible gifts, these Christmas Tree Sugar Cookie Bars are a fun and festive choice. Keep the chocolate chips for extra richness or leave them out for a more traditional sugar cookie flavor. Either way, you’ll have a cheerful Christmas dessert that’s just as enjoyable to decorate as it is to eat.
