These delightful chocolate buckwheat cookies combine rich dark chocolate, toasted hazelnuts, and the distinctive nutty flavor of buckwheat flour. The contrasting textures create an irresistible treat - crispy edges give way to a tender center studded with melted chocolate and crunchy nuts.
A Classic Cookie with a Twist
The earthy, slightly nutty taste of buckwheat flour adds depth and complexity to these cookies. Combined with dark chocolate's intense richness and golden-roasted hazelnuts, each bite delivers layers of flavor. The brown sugar adds subtle caramel notes that perfectly complement the other ingredients.

Baker's Tips
The key to perfect cookies lies in the details. Let the portioned dough spread naturally during baking without pressing down. Properly toasted hazelnuts develop a deeper flavor. Adding toppings while the cookies are still warm ensures they adhere properly and allows the chocolate to melt slightly.
Frequently Asked Questions
- → Why toast the hazelnuts first?
- Toasting brings out a deeper flavor in hazelnuts and makes them crunchier. It also helps you peel off the skins easily, which can sometimes taste bitter.
- → Can I prepare the dough ahead of time?
- Yes! You can keep the dough in your fridge for up to 24 hours. Or, freeze the dough balls for up to a month for later use.
- → Why choose buckwheat flour?
- Buckwheat flour adds a distinct, nutty taste and unique texture to the cookies. Its roasted notes pair wonderfully with chocolate.
- → How can I tell if the cookies are done?
- Look for slightly golden edges with still soft centers after about 11 minutes of baking. They’ll firm up as they cool on the rack.
- → Can I swap out the dark chocolate with others?
- Absolutely, use milk or white chocolate if you like. Dark chocolate, though, offers a great contrast to the sweetness from the nuts.
