Chocolate Hazelnut Cookies (No Sugar, High-Protein)

About This Recipe
I made these when I wanted something that actually tasted like a proper chocolate cookie — dense, rich, with real chocolate pieces and a hazelnut base that makes every bite feel indulgent. The date paste does all the heavy lifting here: it binds everything together and adds natural sweetness without any sugar. The coffee-flavored protein powder in the background makes the chocolate taste deeper. Eight minutes in the oven and you have five cookies that look and taste like they came from a bakery.


Why These Ingredients
Dates — soaked and blended into a paste, they replace both sugar and butter. The result is naturally sticky and sweet with a caramel-like depth. Don’t skip the soaking step — dry dates won’t blend smoothly enough.
Hazelnut butter — adds richness and that classic chocolate-hazelnut flavor. Combined with the date paste it creates a base that holds everything together without any eggs or flour-heavy binding.
Coffee protein powder — deepens the chocolate flavor significantly. You don’t taste coffee directly but it adds a complexity that makes these taste more sophisticated. Any flavor works but coffee or chocolate work best here.
Oat flour — gives the cookies just enough structure without making them dense or cakey. Don’t swap for regular flour — oat flour keeps them soft and slightly chewy.
Warm milk or water — helps bring the dough together and makes the date paste blend more smoothly. Use milk for a richer result or water to keep it lighter.
Stevia chocolate — use a good quality one. It melts into the dough and creates pockets of chocolate throughout. Freeze-dried strawberry on top adds a tartness that cuts through the richness perfectly.

💡Two ways to use the chocolate: I melted the 30g of chocolate and drizzled it over the baked cookies — it sets into a thin glossy layer that makes them look bakery-made. But you can also chop it and fold it into the dough before baking for melty chocolate pockets inside. Both work great, choose what you prefer.
