This rich and decadent chocolate buckwheat cake is perfect for special occasions. It has a sweet, chocolaty glaze that drips down the sides of the cake for a pretty presentation. Serve this buckwheat chocolate cake as a birthday cake or whenever you’re craving an indulgent yet nutritious, gluten-free vegan treat.
Main ingredients
Buckwheat flour is the star of this recipe. If you haven’t tried baking with buckwheat flour yet I highly recommend giving it a try. Buckwheat flour is one of my favorite gluten-free flours because it adds a satisfying texture and an earthy flavor without any hint of that “gumminess” that sometimes plagues gluten-free baked goods. It’s also quite nutrient-rich.
This cake is sweetened with maple syrup. You can substitute honey, agave syrup, or even date syrup instead if you prefer.
I used extra virgin olive oil as the fat in this recipe but any relatively neutral flavored oil will work. Avocado oil or melted coconut oil are good substitutes.
This buckwheat chocolate cake calls for cocoa powder. You can use any type of unsweetened cocoa powder in this recipe (both dutch process cocoa powder as well as natural cocoa powder will work well).
I used coconut milk in this cake but you can use any type of unsweetened plant-based milk you prefer. Almond milk and oat milk are good options.
A small amount of vinegar or lemon juice activates the baking soda in this recipe which helps the cake rise. White vinegar, apple cider vinegar, or lemon juice all work well.
This recipe calls for unsweetened applesauce. You can use either homemade or store bought applesauce in this recipe (just be sure that it doesn’t contain added sugar). Or you can substitute very ripe mashed bananas instead of applesauce if you prefer.
The chocolate glaze calls for arrowroot starch (aka arrowroot flour). Arrowroot starch/flour is a gluten-free and grain-free ingredient that’s perfect for thickening sauces and glazes. I always have some on hand in my pantry and tend to order it online since it can be tricky to find at the grocery store. It adds a deliciously gooey consistency to the glaze.
How to make buckwheat cake
This cake is easy to prepare. Start by preheating your oven, then add the maple syrup, olive oil, unsweetened applesauce, unsweetened plant-based milk, vanilla extract, vinegar or lemon juice, salt, and cocoa powder to a large mixing bowl. Use a whisk to mix those ingredients well.
Next you’ll add the buckwheat flour and baking soda and whisk once more to thoroughly combine those ingredients.
Pour the batter into a 9-inch pan lined with parchment paper, then bake the at 350 degrees Fahrenheit for 35 minutes (or until a toothpick inserted into the middle of the cake looks clean upon removal).
While the cake is baking you can prepare the glaze. It’s very easy to make, but if you’re short on time you can serve the cake without the glaze (it’s delicious that way too, just a little less decadent and more of a casual dessert when served without the glaze).
To make the glaze, add the plant-based milk and arrowroot starch/flour to a saucepan or small pot stir to dissolve. Then you’ll add the cocoa powder, maple syrup, and salt and place it on the stove set to low-medium heat.
Heat that mixture until it noticeably thickens, stirring constantly. Don’t walk away from the stove as this step doesn’t take very long and the glaze may burn quickly if left unattended. Remove the pan from the heat as soon as the glaze has thickened.
Allow both the glaze and the cake to cool to room temperature before pouring the glaze on top of the cake. Once you’ve poured the glaze on top of the cake you can either wait a few hours to allow the glaze to dry or serve it immediately.
Optional additions
For an extra layer of flavor and texture, you can sprinkle some finely chopped nuts such as pecans, almonds, or walnuts on top of the glazed buckwheat chocolate cake while it’s still wet. Freshly grated orange zest is another delicious optional topping you can add if you’re a fan of the orange chocolate flavor combination.
Storage
Store this cake in an airtight container in the fridge for up to three days or in the freezer for up to three months. You can slice the cake before freezing so it’s easy to defrost the perfect amount for a quick dessert.

Hi Jennifer,
I wrote you awhile back, singing the praises of this recipe. I’m curious:
do you use a light or dark buckwheat flour? And which brand? I noticed nature’s path doesn’t make one, perhaps Anita’s organic mill?
Thanks again,
Amy
Thank you! I’ve used Bob’s Red Mill (dark) and Yupik (light) and it turns out well regardless. I’m sure Anita’s would work well too. Glad you enjoyed the cake!
Hi
What can you sub for the arrowroot starch?
Thanks!
I haven’t tried substitutions for the arrowroot starch so I’m not 100% sure, but you could try substituting 2 tablespoons of almond butter or any other type of nut butter or seed butter. But in that case don’t heat the glaze on the stove, simply whisk the ingredients together in a bowl and then drizzle it over the cooled cake.
Amazing recipe! Makes a real cake.
Thank you! Glad you enjoyed it!
