Chocolate chip cookies get an upgrade with the addition of buckwheat flour and black sugar, creating a perfectly balanced treat that’s rich, nutty, and deeply satisfying. Whether you’re looking for a more nutrient-dense cookie or simply want to experiment with new flavors, this recipe delivers both.
Ingredients & Substitutions
- Black sugar: An unrefined sugar used in Chinese traditional medicine and boba tea alike. It has a slightly bitter molasses-like flavor and is packed with iron and trace minerals. It enhances the cookies with a caramelized depth that pairs beautifully with chocolate. Look for it at Asian grocery stores or online.
- Substitute with jaggery, piloncillo, or dark brown sugar.
- Granulated Sugar: This helps balance the black sugar’s strong notes while contributing to the cookie’s crisp edges.
- Melted Butter: Melted butter creates a chewier texture. Make sure the butter is melted then cooled so the sugars do not entirely dissolve into the butter.
- Egg & Egg Yolk: The egg provides structure, while the extra yolk adds richness and chewiness.
- Vanilla Extract: A classic flavor enhancer that complements the nuttiness of buckwheat and the sweetness of the sugars. Essentially dessert MSG.
- All-Purpose Flour: This provides structure, ensuring the cookies hold their shape.
- Make it gluten-free by substituting with a gluten-free flour blend like Cup4Cup or King Arthur Gluten-Free Measure for Measure Flour.
- Buckwheat Flour: Buckwheat flour brings a toasty, nutty flavor to the cookies. It’s also high in fiber and magnesium. Find it in health food markets or speciality grocery stores like Whole Foods. Also available online linked here.
- Kosher Salt: Enhances all the flavors, especially balancing the sweetness of the sugars and chocolate. I use Diamond Crystal Kosher Salt. If using Morton Kosher Salt reduce to 1/3 tsp and if using fine sea salt or table salt use 1/4 tsp.
- Baking Soda: A little goes a long way to give just enough lift to keep the cookies from becoming too dense. They also help the cookies achieve that perfect golden brown color.
- Dark Chocolate: Dark chocolate brings richness and a slight bitterness that balances the sweetness. I used 70% dark chocolate when developing this recipe, but feel free to substitute any dark chocolate or milk chocolate.
