Vegan blueberry buckwheat cake

blueberry buckwheat layer cake

Boy, do I have a cake for you today! It’s really about time. It’s been exactly 20 days since posting a cake, a near-fatal gap of time for someone like me. Yes, it also uses blueberries (frozen ones we picked last summer, specifically), but it’s different. I promise.

What I have here is a cake made with buckwheat. Happens to be gluten-free as well. I stuffed it with blueberry pie filling and frosted the whole business with this nice cashew cream frosting, a perfect complement to the sweet blueberries. Blueberries and buckwheat are a nice complement, too, which is why I decided to make this.

See, we bought a whole bunch of flours at the local Indian market after I got the Everyday Gluten-Free cookbook—sorghum flour, amaranth (okay not flour, but that’s still kinda weird), buckwheat flour...yeah that’s it. But it’s a lot, for me. I usually stick to all-purpose and occasionally whole wheat. So why do I need all of these flours?

My point here is not just to make a gluten-free cake, but to try something new. Explore some new flavors. And this isn’t even that exotic—we’ve had blueberry buckwheat pancakes a few times, always very delicious. But I’ve never used buckwheat to make a cake. 

I know, I'm so boring.

So today I have! And it’s pretty good. Definitely an unusual flavor, but not unwelcome. I got the recipe from Twigg Studios—a beautiful blog that you should totally read—and was pleasantly surprised. No chocolate to be found here, but it works on its own.

I ain’t got much else to say, so here’s the recipe.

Buckwheat cake

Ingredients

110 grams • silken tofu • ½ cup

13 grams • ground flaxseed • 2 tablespoons

90 grams • warm water • ¼ cup plus 2 tablespoons

224 grams • coconut oil, softened • 1 cup

165 grams • light brown sugar • ¾ cup

320 grams • agave nectar • 1 cup plus 1 tablespoon

220 grams • buckwheat flour • 1 ¾ cups plus 2 tablespoons

8 grams • baking powder • 2 teaspoons

3 grams • salt • ½ teaspoon

Directions

Preheat oven to 350 degrees F. Grease two 6-inch round baking pans and line the bottoms with parchment paper.

In a blender, combine silken tofu, flaxseed, and warm water; pulse until smooth. Set aside.

Place coconut oil and brown sugar in the bowl of an electric stand mixer; cream until light and fluffy. With mixer on low speed, pour in tofu mixture and beat until combined. Add agave nectar and vanilla and beat once more. Add flour, baking powder, and salt and mix just until combined.

Divide batter between baking pans and bake for about 35 to 40 minutes, until a toothpick inserted comes out clean. Let cool in pans for 10 minutes before transferring to a wire rack to cool completely.

Cook over medium-low heat until sugar is dissolved and mixture is slightly thickened, 8 to 10 minutes. Remove from saucepan and stir in coconut oil and remaining blueberries. Let cool completely before using.

Cashew cream frosting

Ingredients

160 grams • cashews, soaked in water overnight and drained • 1 cup

112 grams • coconut oil, softened • ½ cup

240 grams • powdered sugar • 2 cups

4 grams • vanilla extract • 1 teaspoon

In a food processor, blend cashews until smooth. Transfer to the bowl of an electric stand mixer and add coconut oil; beat until well-combined. Add powdered sugar along with remaining ingredients and whip until light and fluffy.

Assembly

Ingredients

Buckwheat cake

Blueberry filling

Cashew cream frosting

Directions

Place cake on a work surface and level off the tops of each layer. Cut each layer in half so you have four thinner layers. Fill a piping bag with cashew cream frosting and pipe rings of frosting on one layer; fill with blueberry filling. Repeat so you have a nice four-layer cake. Frost the entire thing with remaining frosting. Top it all off with more blueberry filling if desired.

Not my best frosting job, but whatever.

  1. Great choices on gluten free flours! Those at least have tons of extra nutritions and some protein. And 20 days without cake is away too long! ;-)

  9. omg omg this looks amazing! do you think i could skip the sugar in the recipe and use only (320 g) of agave? i think it already is sweet enough with the agave and adding more sugar seems like too much. thank you for the reply x

    1. You're right, it is a *lot* of sugar...but i'd be cautious about leaving it out entirely since it is a structural ingredient and it could potentially make or break your cake. I bet it would work well with a substitute like stevia or erythritol, so long as you use a "baking blend" that works in baked goods. Let me know what you try! :)
