These decadent buckwheat flour brownies deliver all the fudgy, chocolate richness you crave while being completely gluten-free. The combination of buckwheat flour and quality chocolate creates a brownie that's simultaneously sophisticated and comforting. I discovered this recipe during a quest to create gluten-free treats that don't compromise on texture or flavor.
These brownies have become my signature dessert for gatherings. When I first served them to friends, no one could believe they were gluten-free. Now they specifically request my "buckwheat brownies" whenever we get together.
Ingredients
- Buckwheat flour: Provides a nutty undertone that complements chocolate beautifully. Look for gray-brown varieties for the most authentic flavor.
- Sea salt: Balances the sweetness and enhances the chocolate flavor. Fine sea salt distributes more evenly throughout the batter.
- Unsweetened cocoa powder: Intensifies the chocolate experience. Use Dutch-processed for a smoother taste.
- Chocolate chips: Appear twice in this recipe. Select high-quality semisweet chips around 60% cacao for best results.
- Melted butter: Creates that incomparable fudgy texture. Use European-style butter for richer flavor.
- Eggs: Bind everything together while contributing to the fudgy texture. Room temperature eggs incorporate more smoothly.
- Coconut sugar: Adds caramel notes regular sugar cannot match. Look for unrefined varieties.
- Brewed coffee: Might seem unusual but it magically enhances chocolate flavors without tasting like coffee.
Step-by-Step Instructions
- Preparation:
- Preheat your oven to 350°F and prepare your 8×8 inch pan. Line with parchment paper for easy removal, leaving some overhang on two sides to create handles.
- Mix Dry Ingredients:
- Combine the buckwheat flour, cocoa powder, and salt in a small bowl. Whisk thoroughly to eliminate any lumps and ensure even distribution of the cocoa powder throughout the flour.
- Create Chocolate Base:
- In a medium saucepan over low heat, melt the butter and 1 cup of chocolate chips together. Stir constantly to prevent scorching and remove from heat as soon as smooth. Allow to cool slightly before proceeding.
- Prepare Wet Mixture:
- In a separate bowl, vigorously whisk the eggs and coconut sugar until the mixture lightens slightly in color, about 1 minute by hand. This creates air pockets for a better texture. Add the brewed coffee and mix again. Finally, incorporate the cooled chocolate-butter mixture, stirring until completely combined.
- Combine Everything:
- Pour the dry ingredients into the wet mixture and fold gently with a spatula until just combined and no dry spots remain. Overmixing will develop gluten-like proteins even in gluten-free flour, making brownies tough. Fold in the remaining half cup of chocolate chips.
- Bake to Perfection:
- Pour the batter into your prepared pan, spreading evenly to the corners. Bake for 35-40 minutes, watching carefully toward the end. The brownies are done when the center is set but still gives slightly when pressed. A toothpick inserted should come out with a few moist crumbs but no wet batter.

My absolute favorite thing about these brownies is the complex flavor from the buckwheat flour. The first time I baked them, I was transported back to a tiny café in Paris where I had buckwheat chocolate cake years ago. Something about the earthy quality of buckwheat makes chocolate taste even more luxurious.
Perfect Measuring Technique
The secret to consistently excellent brownies lies in how you measure your flour. Buckwheat flour can easily compact, leading to dense, dry brownies if mismeasured. Always fluff the flour first with a fork or whisk to aerate it, then spoon it gently into your measuring cup until it forms a heap above the rim. Finally, level it off with a straight edge. This method prevents you from using too much flour, which is the most common reason for dry brownies.
The Coffee Secret
Coffee acts as a flavor enhancer for chocolate without making your brownies taste like coffee. The compounds in coffee interact with chocolate to amplify its natural flavors, creating deeper, more complex chocolate notes. If you avoid caffeine, decaf works perfectly. You can also substitute hot water mixed with a teaspoon of instant espresso powder. For those who dislike coffee entirely, simply use hot water instead, though you will miss some depth of flavor.
Storage and Serving
These brownies actually improve with time as the flavors meld together. Store them in an airtight container at room temperature for up to 4 days, or refrigerate for up to a week. The fudgy texture makes them even better when chilled slightly before serving. For longer storage, wrap individual brownies in plastic wrap and freeze for up to 3 months. Thaw at room temperature for about an hour before enjoying. My favorite serving suggestion is slightly warmed with a scoop of vanilla ice cream or a dollop of whipped coconut cream.
