Following the Dukan Diet doesn’t mean giving up cookies altogether. With the right combination of protein-rich ingredients, you can bake delicious biscuits that satisfy your sweet tooth while supporting your weight-loss goals.

These Crispy Dukan Cookies are light, crunchy, and naturally high in protein. Made with whey isolate, wheat gluten, skim milk powder, and a small amount of cornstarch, they deliver a satisfying texture that’s surprisingly close to traditional cookies—without the refined flour or sugar.

Whether you’re looking for a snack with your afternoon coffee or a healthier dessert, this recipe is an excellent addition to your Dukan recipe collection.

Are These Cookies Dukan Friendly?

Yes—but they are intended for the Cruise Phase because they contain tolerated ingredients such as cornstarch and whey isolate.

Unlike traditional cookies, these biscuits contain:

• No wheat flour
• No butter
• No refined sugar
• High-quality protein
• Much lower carbohydrate content

They are ideal for occasional treats while staying within your daily tolerated ingredient allowance.

Dukan Phase Guide

Attack Phase

This recipe is not recommended in its original form because it contains cornstarch and several tolerated ingredients.

Choose simpler protein desserts during the Attack Phase.

Cruise Phase

This is the recommended phase for these cookies.

Enjoy them occasionally while respecting your daily allowance of tolerated ingredients.

Consolidation Phase

Continue enjoying these cookies as a healthier alternative to traditional biscuits.

They pair perfectly with coffee, tea, or fat-free yogurt.

Stabilization Phase

These homemade protein cookies remain a better everyday option than commercially produced cookies high in sugar and refined flour.

Ingredients

Makes approximately 12–15 cookies.

• 1 large egg
• 2 tablespoons whey protein isolate (unflavored)
• 2 tablespoons vital wheat gluten
• 60 g skim milk powder
• 1 tablespoon cornstarch
• Pinch of salt
• Approved sweetener, to taste
• Vanilla extract or vanilla powder (optional)
• Poppy seeds or sesame seeds for topping (optional)

Instructions

Step 1 – Prepare the Dough

In a mixing bowl, combine:

• Whey isolate
• Wheat gluten
• Skim milk powder
• Cornstarch
• Sweetener
• Salt

Add the egg and mix until a soft dough forms.

If desired, add vanilla for extra flavor.

Allow the dough to rest for about 10 minutes.

Step 2 – Roll the Dough

Lightly dust your work surface with a small amount of whey isolate or skim milk powder.

Roll the dough to a thickness of approximately 2–3 mm.

The thinner the dough, the crispier the finished cookies will be.

Step 3 – Cut the Cookies

Use a round cookie cutter or the rim of a glass to cut circles.

Arrange them on a baking tray lined with parchment paper.

Sprinkle with poppy seeds or sesame seeds if desired.

Step 4 – Bake

Preheat your oven to 180°C (350°F).

Bake for 12–15 minutes, or until the cookies become golden brown around the edges.

Allow them to cool completely before serving—they will become even crispier as they cool.

Are sesame or poppy seeds required?

No. They are optional toppings that add texture and visual appeal. You can omit them if preferred.

Can I make these cookies sweeter?

Yes. Adjust the amount of approved Dukan sweetener to suit your taste without affecting the overall texture.
