Learn how to make the best buckwheat chocolate cake with this easy recipe. This gluten-free chocolate cake is a play on the "fallen" chocolate cake made from whipped eggs and sugar with melted chocolate, ground almond, and buckwheat flour folded in before baking. It's delicious with whipped cream and berries or ice cream.
When I worked on this recipe, I wanted a simpler chocolate cake than the typical chocolate layer cake with berries. I was aiming for a single-layer chocolate cake that is quite similar to a flourless chocolate cake of sorts but with a little (buckwheat) flour added to the mix. The buckwheat flour in this recipe not only gives this chocolate cake more flavour, it also helps give the inside of the chocolate cake a little more structure so that, when you underbake it just like you would a real flourless chocolate cake, the cake sinks and settles, but not too much, so it doesn't become overly dense like some other recipes.

What You Need to Make This Gluten-Free Chocolate Cake
The beauty of fallen chocolate cake recipes like this is you likely have most (or all) the ingredients you need in your pantry and fridge. Here's what you need:
- butter—I bake with unsalted butter. If using salted, you may want to adjust the amount of salt you add
- chocolate—I baked this cake with a dark chocolate that is bittersweet (70 % cocoa solids). The flavour and sweetness of the chocolate will have an impact on the sweetness of the cake so use a chocolate you like! The major ingredient is chocolate, which means you MUST use the best dark chocolate for baking because it provides both flavour, structure, and texture to this dessert. For this recipe, I used Cacao Barry Ocoa 70% dark chocolate, which is a professional quality dark chocolate that you can buy in IGA grocery stores in Quebec and online from Vanilla Food Company
- eggs—I always bake with large eggs. If you use smaller or larger eggs, this may have an impact on the texture of the final dessert
- sugar—I used granulated sugar because I find this gives the best volume when whipping the eggs.
- flour—I used gluten-free buckwheat flour. As you can see it is a whole-grain flour, unbleached
- ground almonds—you can use either ground blanched almonds or unblanched. This doesn't matter
- salt—I bake with Diamond Crystal Fine Kosher salt. If using regular table salt, add half the amount or the cake may be too salty.

How to Make a Chocolate Cake With Buckwheat Flour
Step 1—Begin by combining the chocolate and butter in a bowl above a pan of gently simmering water (image 1). Let it all melt together, stirring often, until smooth and glossy (image 2). Set it aside to cool slightly while you whisk together the dry ingredients in a separate bowl (image 3).
Step 2—Place the eggs in the bowl of a stand mixer fitted with the whisk attachment (image 4) and whisk them until frothy before slowly drizzling in the granulated sugar (image 5). Continue whipping until the mixture is very light in colour, creamy, and ribbony (it forms a ribbon when dripped onto the surface as in image 6).
Step 3—Immediately fold the dry ingredients in with a large spatula (image 7) and then the melted chocolate (image 8). The batter will be thick (image 9). Transfer the mixture to a prepared springform pan (image 10).
Tip: Because I wanted a taller chocolate cake, I opted to use an 8-inch springform pan. Make sure to take the time to prepare the cake pan properly: I buttered the pan all over, lined the bottom with parchment paper, and then dusted the sides with buckwheat flour to make sure that this cake would unmould perfectly from the sides, which it did, as you can see in the photos!
Step 4—Make sure the top of the cake is smooth before placing it in the oven (image 11). Bake the cake until it domes on top and begins to pull away from the sides of the pan slightly (image 12). The cake will fall and crack as it cools (image 13). This is normal!
Note: Like with flourless chocolate cakes, it's best to let this cake cool completely and then sit overnight before cutting into it. The cake will sink and settle, and the top will crack a little, and the texture inside of the cake changes as the flavour improves. This recipe makes a great make-ahead dessert. I stored it unwrapped overnight, but feel free to store it under a cake dome. I served this moist chocolate cake with a thick layer of whipped cream and lots of berries. It's the perfect dessert to celebrate summer.
Baking Tip: Volume Without Separating Eggs
A lot of flourless chocolate cake recipes have you separate the whites from the yolks so that you can whip the whites to stiff peaks and fold them into the batter to lighten the mixture. I hate that, and I bet you do too.
Rather than beat the whites separate from the yolks, I opted to make this chocolate cake like I would make a génoise cake, whipping the whole eggs with the sugar until it's at the ribbon stage, a foam so stable, light, and thick that it forms a "ribbon" when drizzled off the beater onto the surface of the whipped mixture. This stable foam is perfect for providing enough rise to this easy gluten-free chocolate cake recipe. No separating of eggs is required!

📖 Recipe
Gluten-Free Buckwheat Chocolate Cake
Ingredients
Gluten-free chocolate cake
- 150 grams unsalted butter
- 175 grams dark chocolate (70 % cocoa content)
- 4 large egg(s)
- 150 grams granulated sugar
- 63 grams buckwheat flour
- 75 grams ground almonds
- ¼ teaspoon Diamond Crystal fine kosher salt
Whipped cream
- 250 mL whipping cream (35 % fat)
- 25 grams icing sugar
Garnish
- 450 grams fresh strawberries
Instructions
Gluten-free chocolate cake
- Preheat the oven to 350ºF (175 °C). Butter the bottom and sides of an 8-inch springform pan, then line the bottom with a round of parchment paper. Use a tablespoon or two of buckwheat flour to flour the buttered sides of the pan. Set the pan aside.
- Melt the butter with the chocolate in a bowl set over a pan of simmering water. Mix until perfectly smooth, glossy, and even. Take the bowl off the heat and let cool slightly.
- Meanwhile, in the bowl of an electric mixer fitted with the whisk attachment, beat the eggs with the granulated sugar to the ribbon stage when the mixture is very pale in colour and extremely light in texture. This takes about 10 minutes.
- In a separate bowl, whisk together the buckwheat flour, ground almonds, and salt. Fold this dry mixture into the fluffy egg mixture. Then fold in the melted chocolate and butter.
- Pour the batter into the prepared springform pan. Smooth the top and tap the pan to remove any large air pockets.
- Bake the cake for about 45 minutes until the surface is set but the inside is still a little underbaked.
- Let the cake cool for 10 minutes then unmold it onto a plate and let it cool and rest overnight. The cake will crack and settle in this time. That's normal!
Whipped cream
- When you are ready to serve the cake, whip the cold whipping cream in a large bowl. When the whipped cream is still a little soft, add the icing sugar and finish whipping the mixture to form thick whipped cream. Spread the whipped cream over the chocolate cake.
Garnish
- Top the whipped cream layer with a pile of washed berries. Serve immediately.
Notes
- For the dark chocolate, I used Cacao Barry Ocoa 70 % dark chocolate.
- You can serve this cake with whipped cream as written, or ice cream (like this vanilla bean ice cream or this dark chocolate ice cream). This would also be excellent with mint chocolate chip ice cream!

does it gave to be left overnight? I don't have time for that.
Janice Lawandi says
Hi! Great question! I actually retested this recipe recently and baked the cake in the morning and served it a few hours later on the same day and it was perfect, so it doesn't have to sit overnight before serving.

I made this for a family lunch party where there was a young family of 4 w gluten issues.
I've been baking for 60 years (!) and I can eat wheat products. Yet I always become anxious when baking gf desserts. And I just don't like the odd (to me) taste of gfree a.p. flour. Even the good ones.
Yet this cake was amazing! We all loved it. Thank you, Janice! I may make it my go-to chocolate cake recipe.
I made it pretty much as was written, but I used Camino semi-sweet chocolate. I worried it might end up too sweet, but it was not.
I made 1.5 x the recipe, and used a 9-inch springform pan. It took a long time to bake, and that worried me. I checked it with a long wooden skewer a few times, and it was repeatedly wet inside. Finally, the skewer came out *fully* clean. Whoops! I shud have baked it a wee bit less. Say until there were still a few moist crumbs on the skewer. Next time!
I used finely ground whole almonds (with skins) and processed them very finely with all of the weighed BW flour (Good Earth brand).
I wasn't sure if I was supposed to use almond flour, or not, bc when I clicked "ground almonds", almond flour was described. But I stayed with ground almonds.
To be on the safe side, I added 1/2 tsp of double-acting bp to my increased recipe. Another link had suggested putting a pan with water at the oven's bottom, so I did that, too.
When I make it again, and if I increase it, I may use 2 x 8" round pans. (Luckily, I own the old-fashioned pans with the movable bar at the bottom).
I buttered the pan as directed, and it came out very easily - even at the sides.
I wrapped the baked cake snugly in plastic wrap overnight, and left it on the counter (no pets!) it was perfect the next day.
I made a lovely white buttercream frosting, and frosted the top with it - I did that for the sake of the 3-year old girl. If it had been just adults, I wud have sprinkled it w icing sugar, and served a side of fresh berries and whipped cream.
The outer crumb was delicate, so I just plopped on little piles of frosting, and then smoothed them lightly together. Worked fine.
This cake was easy to make and so very, very delicious. A nice texture, too. The chocolate flavour was even better than my two old time recipe faves! Who knew?
I now plan to become closer friends w BW flour. I have never used it before, but we have had delicious BW crepes in Brittany, France about 15 years ago.
Thanks, again. This recipe rocks!

The cake is delicious. Thank you for the recipe. I added buckwheat and almond flour to the melted chocolate mixture, then folded in the egg mixture.
45 mins is too long of a baked time. The cake got baked in 35 mins at 350 degrees.
Janice says
Can ground almonds be used to substitute the buckwheat flour?
Serena Lim says
Dear Janice,
Thank you for the lovely recipe. I would like to check the following:
1) can the 175 grams Cacao Barry Ocoa 70% dark chocolate subsitute with Cacao Barry Extra Brute
2) Can the 63g buckwheat flour subsitute Almond Flour? so I will be using all Almond Flour. Please advise thank you
Janice says
Hi Serena,
Ocoa 70 % is a dark chocolate that would contain both cocoa solids and fat (cocoa butter), as well as some sugar, like most 70 % chocolates. In this recipe, the best substitute would be a different 70 % dark chocolate or any bittersweet chocolate.
Extra Brute is a cocoa powder so it would not make a good substitute.
For the almond flour, that could work (might be a little more fudgy, but not in a bad way!), or you could add in some regular all-purpose flour! Hope this helps! Let me know how it goes!

Un superbe gâteau, il doit être succulent, merci pour cette très alléchante réalisation, gros bisous, très bonne soirée ?
Gabby says
That looks so good, perfect for the summer! and I agree, separating the eggs is such a pain. haha
Marlene says
You've outdone yourself with this one! I've been making a flourless chocolate cake for years that involves separating the eggs and processing them separately. I will definitely be trying this cake as the method sounds like it will save me time (and dishes!). Such a beautiful presentation, simple but elegant.
