Ingredients for buckwheat chocolate cake
Earthy buckwheat meets velvety chocolate in this sophisticated plant-based cake—simple ingredients, extraordinary flavor.
| Ingredient | Amount | Notes |
|---|---|---|
| Buckwheat Flour 🌾 | 1 ½ cups | Lightly sifted for even texture |
| Unsweetened Cocoa Powder 🍫 | ¾ cup | Dutch-processed for smooth flavor |
| All-Purpose Flour 🌾 | ½ cup | Balances buckwheat's density |
| Granulated Sugar 🍚 | 1 ¼ cups | Or coconut sugar for deeper flavor |
| Blackstrap Molasses 🍯 | ¼ cup | Adds depth without overpowering |
| Melted Coconut Oil 🥥 | ¾ cup | Cooling slightly before mixing |
| Vanilla Extract 🌿 | 1 tbsp | Pure Madagascar preferred |
| Almond Milk 🥛 | 1 cup | Unsweetened, room temperature |
| Apple Cider Vinegar 🍎 | 1 tbsp | Activates baking soda |
| Baking Soda 🧂 | ½ tsp | Freshly opened for potency |
| Salt 🧂 | ½ tsp | Fine sea salt preferred |
| Dark Chocolate Chips 🍫 | 1 cup | 70% cocoa or higher |
| Walnuts 🌰 | ½ cup | Toasted and roughly chopped |
Buckwheat flour is the star here, so look for light buckwheat groats if grinding your own—it yields a finer texture. Bob's Red Mill or Anthony's Goods are my go-tos for quality, but any reputable brand works. The cocoa powder makes all the difference: Valrhona or Guittard Dutch-processed deliver that velvety smoothness, but Hershey's Special Dark is a solid budget pick. Don't skimp on the blackstrap molasses—its deep, almost bitter notes cut through the sweetness beautifully. For the nuts, toast them in the same oven you'll bake the cake in—just 5 minutes at 350°F—so they're warm and aromatic when mixed in.
No buckwheat flour? Substitute with 100% whole wheat pastry flour, but expect a denser crumb. Running short on cocoa powder? Double the amount of dark chocolate chips (melted and strained) works in a pinch. The almond milk can be swapped for oat or soy milk, but unsweetened is key—flavored versions will throw off the balance. No vanilla extract? Vanilla bean paste gives that extra depth, or a 1 tsp vanilla sugar works if you're in a bind. The walnuts are non-negotiable for texture, but pecans or hazelnuts toasted will work too—just chop them a bit finer for even distribution.
This cake keeps beautifully for 4-5 days when wrapped tightly in plastic at room temperature, or up to 2 weeks in the fridge. For longer storage, slice and freeze portions between parchment paper—3 months is no problem. The texture actually improves after a day or two as the flavors meld. Serve at room temperature with a dusting of cocoa powder or a dollop of vegan whipped coconut cream. The cake's natural moisture means no drying out, even when sliced ahead of time—perfect for make-ahead desserts.

Step-by-step instructions for buckwheat chocolate cake
This cake delivers the perfect marriage of earthy buckwheat and decadent chocolate—rich, moist, and packed with texture.
👨🍳 Step 1: Combine Dry Ingredients with Precision
In a large mixing bowl, whisk together the 1.5 cups buckwheat flour and 0.75 cup unsweetened cocoa powder until fully blended. Sift in the 0.5 cup all-purpose flour and gently fold it in with a spatula. This step ensures even distribution of the dense buckwheat flour, preventing any gritty pockets in your final cake. I like to press the flour mixture through a fine-mesh sieve for extra smoothness—this prevents lumps and guarantees a tender crumb.
Next, add the 1.25 cups granulated sugar, 0.5 tsp baking soda, and 0.5 tsp salt to the dry ingredients. Whisk everything together again until the mixture is homogeneous and no dry spots remain. The baking soda and salt dissolve completely at this stage, which is crucial for proper leavening and flavor balance. Set this bowl aside for now—we'll come back to it after preparing the wet ingredients.
🍳 Step 2: Create the Wet Mixture with Rich Depth
In a separate medium bowl, combine the 0.75 cup melted coconut oil (cooled to room temperature), 0.25 cup blackstrap molasses, 1 tbsp vanilla extract, and 1 cup almond milk. The molasses adds that signature depth, while the coconut oil keeps the cake moist without being greasy. Stir vigorously for 1 minute until the mixture is thoroughly emulsified and smooth. This step is where the cake's complexity begins—don't skip the stirring!
Add the 1 tbsp apple cider vinegar to the wet mixture and stir again. The vinegar reacts with the baking soda to create lift, which is essential for that light, airy texture we're after. You'll see the mixture bubble slightly—this is normal and a good sign! Let this sit for 5 minutes while you prepare the remaining components. This resting period allows the vinegar to fully activate the baking soda.
🥘 Step 3: Fold Wet and Dry Ingredients Together
Gradually pour the wet ingredient mixture into the dry ingredients while stirring gently with a spatula. The goal here is to combine without overmixing—you should still see some flour streaks, but the batter should come together into a thick, fudgy consistency. Here's the thing—buckwheat flour is dense, so don't be surprised if the batter looks thicker than traditional cake batters. This is completely normal and actually contributes to the cake's moist texture.
Once fully combined, fold in the 1 cup dark chocolate chips and 0.5 cup toasted walnuts using gentle folding motions. The walnuts should be roughly chopped and toasted beforehand (toast them in a dry pan over medium heat for 2-3 minutes until fragrant). This adds a delightful crunch that contrasts beautifully with the cake's soft texture. The chocolate chips will melt slightly as the cake bakes, creating pockets of gooey goodness throughout.
🔥 Step 4: Bake to Perfect Moisture and Depth
Preheat your oven to 350°F and grease two 8-inch round cake pans (or line them with parchment paper). Divide the batter evenly between the pans. Here's where precision matters—I use a kitchen scale to ensure both pans have exactly the same amount of batter for even baking. Tap the pans gently on the counter to remove any air bubbles that might have formed during mixing.
Bake for 30-35 minutes or until a toothpick inserted into the center comes out clean with just a few moist crumbs (not wet batter). The cake should spring back slightly when gently pressed in the center. I know it seems counterintuitive, but don't overbake—buckwheat cakes can dry out quickly if left in the oven too long. The top should be set but still slightly shiny, indicating proper moisture retention.
⏰ Step 5: Cool and Layer for Maximum Richness
Remove the cakes from the oven and let them cool in the pans for 10 minutes. Then transfer them to a wire rack to cool completely. This gradual cooling prevents cracking and allows the flavors to meld. While the cakes cool, prepare your favorite chocolate ganache or cream cheese frosting—this cake deserves something equally rich to complement its depth.
Once completely cooled, level the tops if needed (I use a serrated knife for this) and layer with your chosen frosting. The contrast between the earthy buckwheat base and the decadent chocolate layers is what makes this cake truly special. Serve at room temperature for the best texture—each slice should be moist, dense, and packed with that perfect balance of chocolate intensity and nutty complexity.
Pro Tips For Making Buckwheat Chocolate Cake
- WHISK THE MOLASSES FIRST: Blackstrap molasses is thick and stubborn—don’t just toss it in. Whisk it with the wet ingredients first until fully dissolved, or you’ll end up with gritty pockets in your batter. I learned this after pulling out a cake with tiny molasses specks that ruined the texture.
- SIFT THE BUCKWHEAT FLOUR: Buckwheat flour is dense and clumpy—don’t skip sifting it with the all-purpose flour. This prevents a heavy, compact cake. Use a fine-mesh sieve and tap it firmly; yes, it’s tedious, but your cake will thank you with a lighter crumb.
- DON’T OVERMIX THE BATTER: The second you add the dry ingredients, stop mixing after just combining. Overworking the batter introduces too much air, which makes buckwheat cake dense and tough. Fold gently with a spatula—think "just enough to disappear the flour streaks."
- BAKE WITH A COOL PAN: Buckwheat cake rises fast but can sink if the pan is too hot. Chill your baking pan in the freezer for 10 minutes before adding batter. This ensures even rising and a domed top instead of a flat, sad cake. (Yes, even if you’re impatient like me.)
Perfect pairings for this buckwheat chocolate cake
Creamy Frosting Options
For this rich buckwheat cake, I recommend a vegan chocolate ganache made with ½ cup coconut cream and ½ cup dark chocolate (70% cocoa or higher). Heat the coconut cream until steaming, pour over chopped chocolate, then whisk until smooth.
Let it thicken slightly before spreading—this creates that luxurious, velvety texture that complements the cake's earthy notes. 🍫
Fruity Contrasts
Balance the deep chocolate and nutty flavors with bright, fresh fruit. A raspberry compote made from 1 cup raspberries, 2 tbsp maple syrup, and a pinch of salt works beautifully.
Simmer until the berries break down, then strain for a smooth sauce. Drizzle over slices or layer between cake tiers for a tangy contrast that cuts through the richness.
Coffee Infusion
For an adult-friendly twist, add 1 tbsp instant espresso powder to the cake batter for a subtle coffee note that enhances the chocolate. Alternatively, serve with a drip coffee or espresso on the side—this pairing elevates the cake's complexity, making it perfect for dessert after a meal. ☕
Spiced Whipped Cream
Whip 1 cup coconut cream with 1 tsp vanilla extract and a pinch of cinnamon or cardamom for a fragrant topping. The warmth of the spices complements the buckwheat's earthiness while adding a light, airy contrast to the dense cake. Dust with cocoa powder for extra flair.
Boozy Elevations
Add a splash of bourbon or rum—about 2 tbsp—to the batter for depth, or drizzle 1 oz orange liqueur over the top after baking. The citrus notes brighten the chocolate, while the alcohol enhances the cake's moisture and richness. Perfect for special occasions! 🍷
Nutty Crunch Toppers
Toast extra walnuts or pecans until golden, then sprinkle over the cake before serving. For a crunchier texture, make a praline mixture with ½ cup brown sugar, 2 tbsp butter (or coconut oil), and ½ cup chopped nuts, cooked until caramelized.
Let it cool and break into clusters for a sweet, buttery crunch.
Frequently asked questions
Why does buckwheat flour make this cake different from regular chocolate cake?
Buckwheat flour adds a distinctive earthy, slightly nutty flavor that contrasts beautifully with the richness of chocolate. It's also denser than all-purpose flour, which creates a moist, fudgy texture instead of a light, airy crumb. The flour's natural sweetness reduces the need for excess sugar while enhancing the chocolate's depth. Plus, it's a great gluten-free option when combined with the all-purpose flour in this recipe!
Can I make this cake without blackstrap molasses?
Yes! If you don't have blackstrap molasses, substitute with 1 tbsp maple syrup or 1 tbsp dark brown sugar mixed with 1 tsp water. The molasses adds a unique depth, but these alternatives will still create a delicious cake. For best results, use a high-quality dark chocolate to compensate for the missing complexity.
How do I prevent the cake from tasting too bitter? The buckwheat and cocoa can create a strong flavor, but the recipe balances it perfectly. To avoid bitterness,
What's the best way to store leftovers?
Wrap the cake tightly in plastic wrap or store it in an airtight container at room temperature for up to 3 days. For longer storage, slice and freeze portions between parchment paper for up to 3 months. The texture actually improves after a day or two as the flavors meld together—this is normal! Reheat slices in the microwave for 10-15 seconds if you prefer them warm.
Can I make this cake in a single 9-inch pan instead of two 8-inch pans?
Yes, but you'll need to adjust the baking time. Use a 9-inch round pan and bake for 40-45 minutes instead of 30-35 minutes. The cake will be slightly taller but still moist. For even baking, place the pan on the middle rack and avoid opening the oven door during the first 20 minutes of baking. The center should test clean with a toothpick.
