Festive Cookie Bars are the kind of holiday treat that disappears fast from every dessert tray. They have a soft, buttery cookie bar base topped with a thick layer of creamy frosting and finished with bright red and green sprinkles for that cheerful seasonal look.

These bars are easy to make, simple to slice, and perfect for cookie exchanges, classroom parties, holiday gatherings, or a cozy baking afternoon at home. If you want a dessert that feels classic, colorful, and crowd-pleasing, Festive Cookie Bars check every box.

Festive Cookie Bars bring together everything people love about holiday baking in one easy pan. You get the rich flavor of a sugar cookie, the softness of a bakery-style bar, and the fun finish of a frosted Christmas dessert without needing to scoop or roll individual cookies.

They are also wonderfully flexible. You can keep them simple with vanilla frosting, add almond extract for a bakery-style touch, or change the sprinkle colors for different celebrations throughout the year.

These ingredients work together to create soft cookie bars with a tender crumb and a smooth frosting that holds sprinkles beautifully.

For the cookie bars:

1 cup unsalted butter, softened
1 cup granulated sugar
2 large eggs
2 teaspoons vanilla extract
1/2 teaspoon almond extract, optional
2 1/2 cups all-purpose flour
1 teaspoon baking powder
1/2 teaspoon salt

For the frosting:

1/2 cup unsalted butter, softened
2 cups powdered sugar
2 to 3 tablespoons heavy cream or milk
1 teaspoon vanilla extract
Pinch of salt

For the topping:

3 to 4 tablespoons red and green holiday sprinkles

Ingredient notes:

Butter gives these bars their rich flavor, so using real unsalted butter makes a big difference. Vanilla keeps the flavor warm and classic, while a tiny splash of almond extract adds that nostalgic holiday bakery taste. Heavy cream creates a fluffier frosting, but milk works well too if that is what you have on hand.

These bars come together in a few simple steps, and the method is beginner-friendly. Let the bars cool fully before frosting so the topping stays thick and creamy.

Step 1: Prep the pan and oven

Preheat your oven to 350°F. Line a 9×13-inch baking pan with parchment paper or lightly grease it well. This makes lifting and slicing the bars much easier once they cool.

Step 2: Cream the butter and sugar

In a large mixing bowl, beat the softened butter and granulated sugar until light and fluffy. This usually takes 2 to 3 minutes and helps create a soft texture in the finished bars.

Step 3: Add the eggs and extracts

Mix in the eggs one at a time, then stir in the vanilla extract and almond extract if using. Scrape down the sides of the bowl so everything blends evenly.

Step 4: Add the dry ingredients

In a separate bowl, whisk together the flour, baking powder, and salt. Add the dry ingredients to the wet mixture and mix just until a soft dough forms. Do not overmix, or the bars can turn dense.

Step 5: Press and bake

Transfer the dough to the prepared pan and press it into an even layer. Bake for 18 to 24 minutes, or until the edges are lightly golden and the center looks set. Avoid overbaking if you want tender, soft cookie bars.

Step 6: Cool completely

Let the bars cool in the pan until they reach room temperature. This step is important because warm bars will melt the frosting.

Step 7: Make the frosting

Beat the softened butter until smooth. Add the powdered sugar, vanilla extract, pinch of salt, and 2 tablespoons of cream or milk. Beat until fluffy, adding a little more cream if needed for a spreadable texture.

Step 8: Frost and decorate

Spread the frosting over the cooled bars in an even layer. Immediately scatter the red and green sprinkles over the top so they stick well.

Step 9: Slice and serve

Lift the bars from the pan, slice into squares or rectangles, and serve. For neat slices, chill them for 15 to 20 minutes before cutting.

Festive Cookie Bars are perfect on a holiday dessert board alongside fudge, truffles, and classic cookies. They also pair nicely with coffee, hot chocolate, or a cold glass of milk.

Store the bars in an airtight container at room temperature for up to 3 days or in the refrigerator for up to 1 week. If stacking them, place parchment paper between the layers to protect the frosting. You can also freeze unfrosted bars for up to 2 months, then thaw and frost before serving.

Frequently Asked Questions

Yes. You can bake the bars a day ahead, keep them covered, and frost them the next day before serving.

Can I use store-bought frosting?

You can, but homemade frosting gives a fresher flavor and a softer texture that works especially well with these cookie bars.

This usually happens from overbaking or measuring too much flour. Pull them out when the center is set and the edges are only lightly golden.

Can I change the sprinkle colors?

Absolutely. Use pastel colors for spring, orange and black for Halloween, or rainbow sprinkles for birthdays.

Do I need almond extract?

No. It is optional, but it adds a classic bakery-style flavor that many people love in frosted sugar cookie bars.

Yes, but the texture of some sprinkles may soften a bit after thawing. Freeze them in a single layer first, then store them in a well-sealed container.
