Soft, buttery, and dressed up for the holidays, these Christmas Cookie Bars are the kind of festive treat that disappears fast from any dessert table. They have that classic sugar-cookie flavor, a tender cake-like crumb, and a thick layer of creamy frosting on top, all finished with cheerful red and green sprinkles that make them look instantly celebration-ready.

What I love most about these bars is how easy they are compared to rolling and cutting out individual cookies. You still get all the cozy holiday charm, but in a simple pan-baked dessert that slices beautifully and feeds a crowd. Whether you’re baking for a cookie exchange, a classroom party, or just want something sweet for a December weekend, these bars bring plenty of Christmas spirit without extra fuss.

These bars are a holiday baking win for so many reasons. First, they give you all the flavor of a frosted sugar cookie in a much easier format. No chilling dough, no rolling pins, and no cookie cutters covering the counter. Just press the batter into a pan, bake, frost, and slice.

They’re also wonderfully soft in the center with lightly golden edges, which makes every bite rich and satisfying. The frosting adds a smooth, sweet finish that pairs perfectly with the buttery base, and those festive sprinkles make them feel special enough for gifting or holiday gatherings. If you need a dependable Christmas dessert that looks impressive and travels well, this one checks every box.

Holiday baking can get busy fast, so recipes that save time without sacrificing flavor are always worth keeping around. Christmas Cookie Bars are perfect because they deliver the nostalgic flavor of holiday sugar cookies in a quicker, more relaxed way. Instead of shaping dozens of cookies, you bake one pan and cut it into neat squares.

They’re also easy to customize. You can use different sprinkle colors, add a touch of almond extract for a bakery-style flavor, or swap the frosting style depending on the occasion. They look cheerful, taste familiar, and fit right in alongside every classic holiday dessert.

The ingredient list is made up of simple baking staples, and each one plays an important role in giving these bars their soft texture, rich flavor, and festive finish.

Butter
Butter gives the bars their rich, classic cookie flavor and helps create a soft, tender crumb.

Granulated sugar
Sugar sweetens the dough and helps the bars bake up light with a delicate texture.

Eggs
Eggs bring structure and moisture, helping the bars stay soft while holding together cleanly when sliced.

Vanilla extract
Vanilla adds warmth and that familiar bakery-style sweetness that makes these bars taste like the holidays.

Almond extract
A small amount of almond extract adds a festive sugar-cookie flavor that makes the bars extra special.

All-purpose flour
Flour forms the base of the dough and gives the bars enough structure to bake into soft, sturdy squares.

Baking powder
Baking powder lifts the dough and helps create a light, fluffy texture instead of a dense bar.

Salt
Salt balances the sweetness and keeps the flavor from tasting flat.

Milk
A little milk softens the batter and helps create a smooth, spreadable consistency.

Powdered sugar
Powdered sugar is the base of the frosting, giving it that creamy, fluffy texture.

Heavy cream
Heavy cream makes the frosting smooth and luscious while helping it spread easily over the cooled bars.

Red and green sprinkles
Sprinkles bring the festive finishing touch and make these bars instantly look like Christmas.

This recipe comes together in a few easy steps, and once the bars are cooled, decorating them is the fun part. Work gently with the batter, avoid overbaking, and you’ll end up with soft, bakery-style bars every time.

Step 1: Prep the pan and oven

Preheat your oven to 350°F. Grease or line a 9×13-inch baking pan with parchment paper so the bars lift out easily once cooled.

Step 2: Cream the butter and sugar

In a large mixing bowl, beat the butter and granulated sugar until the mixture looks pale and fluffy. This step helps create a soft, tender texture.

Step 3: Add the wet ingredients

Mix in the eggs one at a time, then add the vanilla extract and almond extract. Stir until the mixture is smooth and fully combined.

Step 4: Add the dry ingredients

In a separate bowl, whisk together the flour, baking powder, and salt. Gradually add the dry mixture to the wet ingredients, then mix in the milk until a soft batter forms.

Step 5: Spread and bake

Transfer the batter to the prepared pan and spread it evenly into the corners. Bake until the top is set and the edges are lightly golden. Be careful not to overbake, since that can dry the bars out.

Step 6: Cool completely

Let the bars cool in the pan until they reach room temperature. Frosting warm bars will cause the topping to melt and slide.

Step 7: Make the frosting

Beat together the butter, powdered sugar, vanilla, heavy cream, and a tiny splash of almond extract if you want even more holiday flavor. Mix until the frosting is smooth and fluffy.

Step 8: Frost and decorate

Spread the frosting evenly over the cooled bars, then finish with red and green sprinkles. Slice into squares and serve.

These Christmas Cookie Bars make a great holiday dessert for parties, potlucks, and cookie trays because they slice neatly and serve easily. A 9×13-inch pan will usually feed 16 people if you cut medium squares, or up to 24 people if you make smaller party-size pieces.

For serving, they’re best at cool room temperature when the frosting is soft and creamy. If you’re making them ahead, store the bars in an airtight container. They can sit at room temperature for about 2 days in a cool kitchen, or stay fresh in the refrigerator for up to 5 days. If chilled, let them sit out for a bit before serving so the texture softens again.

You can also freeze unfrosted or frosted bars in layers with parchment paper between them. Thaw overnight in the fridge or on the counter before serving.

Hot chocolate

A mug of rich hot chocolate makes these frosted bars feel even more festive and cozy.

Coffee

Fresh coffee balances the sweetness beautifully and makes these bars perfect for an afternoon treat.

Peppermint mocha

That cool minty note pairs especially well with buttery cookie bars during the holiday season.

Vanilla ice cream

A scoop of vanilla ice cream turns a simple bar into an easy plated dessert for guests.

Fresh berries

Strawberries or raspberries add a bright, slightly tart contrast to the sweet frosting.

Spiced chai tea

Warm chai spices bring extra seasonal flavor and pair nicely with the soft sugar-cookie base.

Serve these alongside truffles, shortbread, and other Christmas treats for a festive dessert spread.
