If you’ve ever seen little cookies that look exactly like walnuts, you’ve probably discovered Polish Orzeszki cookies! These beautiful, old-fashioned treats are made with delicate golden cookie shells and a rich, creamy caramel filling.

Orzeszki means “little nuts” in Polish, and the name describes them perfectly. Each cookie consists of two hollow walnut-shaped shells joined together with a delicious filling.

These cookies are especially popular during Christmas, weddings, and family celebrations. They’re wonderful for holiday cookie platters, homemade gifts, and anyone who loves traditional European baking.

The best part? Once you learn how to use a walnut cookie mold, making these charming little treats becomes surprisingly simple.

What Are Polish Orzeszki Cookies?

Polish Orzeszki are traditional walnut-shaped sandwich cookies made using a special cookie iron or mold.

Unlike regular cookies baked on a flat baking sheet, Orzeszki are cooked inside walnut-shaped cavities that create their distinctive ridged appearance.

After baking, the hollow shells are filled with caramel, walnut cream, chocolate filling, or other sweet mixtures.

This version uses a buttery cookie dough and a creamy dulce de leche filling inspired by the caramel-colored filling shown in the accompanying Reel.

Ingredients for Polish Orzeszki Cookies

For the Cookie Shells

• 2½ cups (315 g) all-purpose flour
• ½ cup (113 g) unsalted butter, softened
• ⅓ cup (67 g) granulated sugar
• 1 large egg
• ¼ cup (60 g) sour cream
• ½ teaspoon baking powder
• ¼ teaspoon salt
• 1 teaspoon vanilla extract

For the Caramel Filling

• 1 cup (240 g) thick dulce de leche
• ¼ cup (57 g) unsalted butter, softened
• ½ cup (55 g) finely ground toasted walnuts (optional)
• ½ teaspoon vanilla extract
• Pinch of salt

Equipment Needed: A stovetop or electric walnut-shaped cookie mold, mixing bowls, hand mixer, cooling rack, and small spoon or piping bag.

How to Make Traditional Polish Orzeszki Cookies

Step 1: Prepare the Cookie Dough

In a large mixing bowl, beat the softened butter and sugar together until light and creamy.

Add the egg, sour cream, and vanilla extract. Continue mixing until everything is combined.

In a separate bowl, whisk together the flour, baking powder, and salt.

Gradually add the dry ingredients to the wet mixture, stirring until a soft dough forms.

The dough should be smooth and easy to handle without sticking excessively to your fingers.

If it feels too soft, refrigerate it for approximately 20–30 minutes.

Step 2: Shape the Dough into Small Balls

 

Divide the prepared dough into small, equal-sized portions.

Roll each portion between your palms to create a smooth ball.

Depending on your mold, each ball should contain approximately 1–1½ teaspoons of dough.

Try to keep the balls similar in size so the shells bake evenly.

Helpful Tip: Start with one test cookie to determine the correct amount of dough for your particular walnut mold.

Step 3: Bake the Walnut-Shaped Cookie Shells

 

Preheat your walnut cookie iron according to the manufacturer’s instructions.

Lightly grease the mold cavities if required.

Place one small dough ball inside each cavity, then carefully close the mold.

Cook until the shells become lightly golden and firm.

For many stovetop molds, this takes approximately 2–4 minutes, although the exact cooking time depends on the equipment and heat level.

Remove the shells carefully and transfer them to a cooling rack.

Allow them to cool completely before filling.

If necessary, trim excess dough from the edges to create neat walnut halves.

Step 4: Prepare the Creamy Caramel Filling

In a medium bowl, beat the softened butter until smooth and fluffy.

Gradually add the thick dulce de leche, mixing until the filling becomes creamy.

Stir in the vanilla extract and a small pinch of salt.

If you prefer a nutty filling, fold in the finely ground toasted walnuts.

The finished mixture should be thick enough to stay inside the cookie shells without running.

If the filling becomes too soft, refrigerate it briefly before assembling the cookies.

Step 5: Fill the Walnut Cookie Shells

Arrange the cooled cookie shells on a clean work surface.

Using a small spoon or piping bag, fill the hollow center of each shell with the caramel mixture.

Avoid adding too much filling, since it may squeeze out when the two halves are pressed together.

For a neat appearance, spread the filling evenly toward the edges.

Step 6: Assemble the Orzeszki Cookies

Take two filled cookie shells and gently press them together.

The two halves should form a complete walnut shape.

Wipe away any excess caramel filling around the edges.

Repeat until all the shells are assembled.

Arrange the finished cookies on a serving platter or inside an airtight container.

For a slightly softer texture, allow the cookies to rest overnight in the refrigerator before serving.

Tips for Perfect Polish Walnut Cookies

Use a proper walnut cookie mold. The special mold is essential for creating the traditional walnut appearance.

Don’t overfill the mold. Excess dough can spill out and create thick edges.

Keep the dough balls consistent. Uniform portions help the cookies bake evenly.

Allow the shells to cool. Warm cookie shells can melt or soften the caramel filling.

Choose thick dulce de leche. A firm caramel filling holds the cookie halves together more effectively.

Make them ahead. Preparing the shells in advance makes holiday baking easier.

Delicious Filling Variations

Traditional Polish Orzeszki can be prepared with several different fillings.

Chocolate Walnut Filling

Mix cocoa powder into a butter-based filling and add finely chopped toasted walnuts for a rich chocolate flavor.

Classic Walnut Cream

Combine ground walnuts with a thick, sweet buttercream for a nutty variation.

Caramel and Sea Salt

Add a small pinch of flaky sea salt to the dulce de leche filling for a sweet-and-salty combination.

Chocolate Hazelnut Filling

Use a thick chocolate-hazelnut spread for a simple alternative that pairs beautifully with the buttery cookie shells.

How to Store Polish Orzeszki Cookies

Refrigerator: Store assembled cookies in an airtight container for up to five days. Allow them to sit at room temperature briefly before serving.

Room Temperature: Unfilled shells can be kept in an airtight container in a cool, dry place for several days.

Freezer: Freeze unfilled cookie shells for up to two months. Thaw completely before adding the filling.

For the best texture, prepare the shells ahead of time and fill them the day before serving.

Frequently Asked Questions

What does Orzeszki mean?

Orzeszki is Polish for “little nuts.” The cookies are named after their walnut-like shape.

Do I need a special cookie iron?

Can I make Orzeszki without walnuts?
