Yugoslavian Christmas Cookies are a festive layered dessert with a buttery pastry base, fruity blackberry jam, and crisp walnut-lemon meringue. They bake in one pan, slice beautifully for holiday trays, and offer a satisfying mix of tender, crunchy, sweet, and nutty textures.

These old-fashioned bar-style cookies are especially good when you want something a little different from classic cutout cookies. Instead of rolling and shaping individual pieces, you build the dessert in layers and bake everything together in one pan.
The combination works because each layer brings something distinct. The tender butter dough supports the jam without becoming overly sweet, while the blackberry filling adds a bright fruitiness that balances the rich walnuts. On top, whipped egg whites bake into a lightly crisp meringue flavored with lemon.
They are also practical for Christmas baking because one pan produces plenty of pieces. Once cooled, the cookies can be cut into small squares or rectangles, making them a convenient addition to cookie boxes, dessert platters, and holiday gatherings.
Yugoslavian Christmas Cookies Ingredients
Unsalted butter: Softened butter creates the rich, tender pastry base. Bringing it to room temperature before mixing helps it cream smoothly with the sugar.
Granulated sugar: Sugar is used in both the dough and the meringue, giving the pastry gentle sweetness while helping the egg whites become glossy and crisp during baking.
Egg yolk: Adds richness and helps bind the crumbly butter dough together.
All-purpose flour: Provides the structure for the short, tender bottom layer.
Salt: A small amount sharpens the buttery flavor and keeps the cookie base from tasting overly sweet.
Egg whites: Whipped egg whites form the airy meringue topping. They should be beaten until firm peaks develop before the sugar is gradually incorporated.
Walnuts: Finely ground walnuts are folded into the meringue, while coarsely chopped walnuts add texture across the top.
Lemon extract: Gives the walnut meringue a subtle citrus note that complements the sweet berry filling.
Seedless blackberry jam: Creates the soft, fruity center between the pastry and meringue. Seedless jam is particularly helpful because it keeps the layers smooth and makes the finished cookies easier to slice.

Cooking Steps
STEP 1: Heat your oven to 350°F (175°C) and prepare either an 11 × 16-inch jelly roll pan or a 9 × 13-inch baking pan. Make sure the butter is properly softened before beginning so it blends easily into the dough.
STEP 2: Beat the softened butter with the smaller portion of granulated sugar until pale and fluffy. Mix in the egg yolk and salt, then gradually work in the flour. The finished mixture will be more crumbly than a typical cookie dough, which is exactly what you want.
STEP 3: Press the dough firmly and evenly over the bottom of the pan. Take a little time with this step so the base has an even thickness from edge to edge. If the mixture sticks to your fingertips, dust your hands lightly with flour before continuing.
STEP 4: In a clean mixing bowl, whip the egg whites until they hold stiff peaks. Gradually beat in the remaining sugar rather than adding it all at once. Continue whipping until the mixture looks thick, firm, and glossy.
STEP 5: Fold the finely ground walnuts and lemon extract gently into the whipped whites. Use broad, careful strokes so you keep as much air in the meringue as possible. Overmixing can cause the topping to lose some of its light texture.
STEP 6: Loosen the blackberry jam with a fork or spoon, then carefully spread it over the unbaked pastry layer. Add the walnut meringue on top and gently spread it to the edges without disturbing the jam underneath. Sprinkle the chopped walnuts evenly across the surface.
STEP 7: Bake for about 40 minutes, watching closely during the final portion of baking. The meringue should look dry, lightly crisp, and golden rather than dark brown. Remove the pan from the oven and slice the cookies while they are still warm, then allow them to cool completely.
Helpful Tips
- Grind the meringue walnuts finely. Smaller walnut pieces fold into the whipped egg whites more evenly and give the baked topping a smoother, more delicate texture.
- Be gentle with the meringue. Fold rather than vigorously stirring after the egg whites have been whipped. Preserving those air bubbles helps create the crisp, light upper layer.
- Slice with a serrated knife. Use a gentle sawing motion instead of pressing straight down. This reduces cracking and keeps the fragile meringue attached to the blackberry layer.
Can I use a 9 × 13-inch pan?
Yes. A 9 × 13-inch baking pan works well if you do not have an 11 × 16-inch jelly roll pan. Because the smaller pan produces slightly thicker layers, begin checking the cookies around the expected baking time and rely on the appearance of the meringue to judge doneness.
Why should the cookies be cut while warm?
The meringue becomes more brittle as it cools completely. Cutting the bars while they are still warm allows your knife to pass through the topping more cleanly, reducing the chance that large sections of the crisp meringue will crack or separate.
Let the cut pieces remain in the pan afterward until they have cooled enough to hold their shape comfortably.
What can I use instead of blackberry jam?
Another smooth, seedless fruit preserve can work when blackberry jam is unavailable, although it will change the traditional flavor profile of the cookies. Raspberry or another pleasantly tart berry preserve is especially suitable because its acidity balances the buttery base and sweet walnut meringue.
Avoid very chunky preserves because large fruit pieces can make the meringue layer harder to spread evenly.
How do I know when the meringue is finished baking?
Look for a dry, lightly crisp surface with a pale golden color. The topping should no longer appear wet or foamy in the center.
Because ovens and pan sizes vary, appearance is more useful than relying only on the clock. Keep an especially close eye on the surface toward the end of the approximately 40-minute baking period so the walnuts and meringue do not become too dark.

Can I make Yugoslavian Christmas cookies ahead of time?
Yes. These layered cookies are well suited to advance holiday preparation because they can cool completely before being stored and served later. In fact, waiting until the bars have fully cooled gives the pastry and jam layers time to settle, making the individual pieces easier to handle.
For the neatest presentation, slice them while warm but leave them undisturbed until completely cooled.
Perfect Pairings
Coffee or espresso: The slightly bitter edge of coffee balances the buttery pastry, sweet blackberry jam, and walnut meringue particularly well.
Hot tea: Black tea or a simple lemon tea works nicely with the citrus note in the meringue without overwhelming the delicate nutty flavor.
Christmas cookie platter: Serve these alongside simpler butter cookies or lightly spiced holiday cookies. Their visible jam and meringue layers give a dessert tray useful contrast in both texture and appearance.
Keeping Leftovers Fresh
Allow the cookies to cool completely before transferring them to a storage container. Arrange them in a single layer when possible, or separate stacked layers with parchment paper so the meringue surfaces do not stick together or become crushed.
Store the cookies in a tightly covered container at cool room temperature for about 2 days. For longer storage, refrigerate them for approximately 4 to 5 days. Keep in mind that refrigeration can gradually soften the crisp meringue as moisture from the jam moves into the topping.
For extended storage, freeze the cooled pieces in a freezer-safe container with parchment between the layers for up to about 2 months. Thaw them in the refrigerator or at room temperature before serving. Reheating is generally unnecessary and can soften the jam or damage the delicate meringue, so these cookies are best enjoyed once they have returned to a comfortable serving temperature.

Yugoslavian Christmas Cookies
Ingredients
For the dough
- 1 cup unsalted butter softened to room temperature, approximately 70°F
- 1 large egg yolk
- 1/2 teaspoon salt
- 2 1/2 cups all-purpose flour such as King Arthur
- 1/2 cup granulated white sugar
For the meringue
- 1 teaspoon lemon extract
- 3/4 cup walnuts finely ground for a smoother-textured meringue
- 4 large egg whites
- 1 cup granulated white sugar
For assembly and topping
- 1 cup seedless blackberry jam such as Polaner
- 1/4 cup walnuts chopped
Instructions
- Prepare the dough. Preheat the oven to 350°F (175°C). Have an 11 × 16-inch jelly roll pan or a 9 × 13-inch baking pan ready.
- Using a hand mixer or stand mixer, beat the softened butter with 1/2 cup sugar until the mixture becomes pale, light, and fluffy.
- Mix in the egg yolk and salt until thoroughly incorporated.
- Add the flour gradually, continuing to mix until a crumbly dough forms.
- Press the dough evenly across the bottom of the prepared pan. Lightly flour your hands as needed to keep the dough from sticking while pressing it into place.
- Prepare the meringue. Using a mixer fitted with a whisk attachment, whip the egg whites until stiff peaks develop.
- Slowly incorporate 1 cup sugar while continuing to beat the whites. Whip until the meringue is firm and glossy.
- Carefully fold the finely ground walnuts and lemon extract into the meringue without excessively stirring or deflating the whipped whites.
- Assemble the layers. Stir or loosen the blackberry jam with a fork until it is easy to spread, then distribute it evenly over the unbaked dough.
- Gently spread the walnut meringue across the jam layer, creating light swirls over the surface if desired.
- Scatter the chopped walnuts evenly over the meringue.
- Bake the cookies. Transfer the pan to the preheated oven and bake for approximately 40 minutes, or until the meringue develops a crisp, golden surface.
- Watch the cookies toward the end of baking so the meringue does not become excessively browned.
- Cut and cool. Remove the pan from the oven and cut the cookies into pieces while they are still warm. Use a serrated knife with a gentle back-and-forth sawing motion to minimize cracking or crushing the fragile meringue.
- If a section of meringue breaks away during slicing, carefully press it back against the jam layer beneath it.
- Allow the cookies to cool completely, either in the baking pan or after transferring them to a wire cooling rack.
