If you’ve ever visited Eastern Europe, you’ve probably seen Oreshki—the famous walnut-shaped sandwich cookies filled with a rich creamy center. Traditionally they’re made with butter, sugar and caramelized condensed milk, making them unsuitable for the Dukan Diet.

Fortunately, this Dukan adaptation recreates the same nostalgic look and delicate texture while replacing refined flour and sugar with protein-rich ingredients. The result is a surprisingly light, satisfying dessert that fits perfectly into a high-protein lifestyle.

These little cookies are ideal for special occasions, afternoon coffee, or simply when you’re craving something sweet without leaving your Dukan plan.

Consolidation Phase

✅ Excellent choice.

Enjoy as an occasional homemade dessert while maintaining portion control.

Stabilization Phase

✅ Perfect as a healthier alternative to traditional cookies.

Ingredients

For the Cookie Shells

• 2 tablespoons light margarine (or reduced-fat spread)
• 4 tablespoons oat bran
• 2 tablespoons cornstarch (about 20 g)
• 3 tablespoons skimmed milk powder (30 g)
• 1½ cups whey protein isolate
• 2 eggs
• 1 teaspoon baking powder
• Sweetener equivalent to 4–5 tablespoons sugar
• Optional: 1 teaspoon cocoa powder for half of the dough

For the Filling

Dukan Sweetened Condensed Milk

• Fat-free cottage cheese
• Sweetener
• A pinch of baking soda
• Optional:
  • Skimmed milk powder
  • Vanilla
  • Whey protein powder

The filling becomes thick and caramel-like after gentle heating and cooling.

Instructions

Step 1 – Prepare the Dough

In a large bowl combine:

• Oat bran
• Cornstarch
• Whey isolate
• Baking powder
• Sweetener

Add the eggs and softened margarine.

Mix until a soft dough forms.

Finally knead in the skimmed milk powder. The dough should feel soft but not sticky.

If desired, divide the dough in half and add cocoa powder to one portion for chocolate shells.

Step 2 – Shape the Cookies

Roll the dough into small balls about the size of a walnut.

Lightly grease and preheat an Oreshki mold (walnut cookie mold).

Place one dough ball into each cavity.

Bake until golden brown.

The shells should release easily once fully cooked.

Allow them to cool completely.

Step 3 – Make the Filling

Combine:

• Fat-free cottage cheese
• Sweetener
• Baking soda

Optionally add skimmed milk powder or whey protein for a thicker consistency.

Microwave in short intervals, stirring every 30 seconds, until the mixture becomes smooth and creamy.

Cool completely before filling the cookies.

Step 4 – Assemble

Fill one cookie half with the cream.

Press a second shell on top to create the classic walnut shape.

Refrigerate for at least one hour before serving for the best texture.

Tips for Success

• Preheat the walnut mold thoroughly before adding the dough.
• Lightly grease the mold to prevent sticking.
• Do not overfill the shells.
• Let the filling cool completely before assembling.
• The cookies taste even better the following day as the filling softens the shells slightly.

Frequently Asked Questions

Can I make these without a walnut mold?

The signature shape requires a special Oreshki mold, but you can bake small sandwich cookies using silicone molds or mini tart molds as an alternative.

Can I use butter instead of margarine?

Yes, if your Dukan phase allows it. However, using a reduced-fat spread helps keep the recipe lighter.

Can I freeze the finished cookies?

Yes. Freeze them in an airtight container and thaw overnight in the refrigerator.

Can I flavor the filling?

Absolutely. Vanilla, coffee extract, cocoa powder, cinnamon, or lemon zest all work well.

Are these cookies suitable for meal prep?

Yes. They often taste even better after resting overnight because the shells absorb a little moisture from the filling.
