This Vegan Sweet Potato Chocolate Cake really takes the cake.
Looking for a healthy cake that’s full of dense, chocolate flavor? This vegan chocolate cake is fresh and moist, and the cake and frosting are both made with sweet potatoes. Oh yes!

Yes, a long recipe name. Worth every syllable, because this healthy chocolate cake is a PPF sensation.
And, do we really need another chocolate cake recipe?
What makes this Sweet Potato Chocolate Cake special?
You could say this one is special because it’s vegan, whole-grain, oil-free.
Or, that it’s special because it has nutrient-dense sweet potatoes in both the frosting and cake.
But, I think it’s special in that the whole is far more than the sum of its parts.
And, it’s special because of how readers are embracing it, and celebrating special family times with this recipe!
I was pretty fond of this recipe when I created it. My family was too. But, I truly didn’t know how all of you would feel about it.
It’s not a classic chocolate cake with a hefty dose of sugar and fat.

So, I wondered how well a ‘chocolate sweet potato cake’ would be accepted!
I had a fair idea through recipe testing, when one of my (very) oil-free-skeptical friends tried it for the first time.

He didn’t know it was oil-free, and said he was shocked because it was one of the best chocolate cakes he had tasted!
Then, other reports came in from testers – and now from many of you.

Our facebook group has been posting pic after pic of this cake, and it’s become a bit of a sensation in the group!
That’s it, I couldn’t resist any longer.
This Chocolate Sweet Potato Cake recipe is now yours, all yours.

Sweet Potato Chocolate Cake with Chocolate Sweets Frosting
Ingredients
Cake
- 3/4 cup peeled cooked, and cooled orange sweet potato (see note)
- 1/2 cup plus 1 tablespoon water divided
- 1/4 cup pure maple syrup
- 1 tablespoon balsamic vinegar
- 2 teaspoons pure vanilla extract
- 1 cup whole-grain spelt flour
- 1/3 cup coconut sugar
- 1/4 cup mini or regular nondairy chocolate chips
- 1/2 tsp scant sea salt
- 1/4 cup cocoa powder
- 1 teaspoon baking powder
- 1 tsp scant baking soda
Frosting
- 1 cup loosely packed peeled cooked, and cooled sweet potato (see note)
- 2/3 – 3/4 cup coconut sugar or other unrefined sugar see note
- 1/2 cup cocoa powder
- 1/2 cup scant raw cashew butter or almond butter
- 1/4 tsp rounded sea salt
- 2-5 tbsp nondairy milk see tip
- 1 teaspoon pure vanilla extract
Instructions
Cake
- Preheat oven to 350°F.
- Lightly coat an 8” x 8” brownie/cake pan or a 9” round cake pan with coconut or other oil, and fit the bottom of the pan with a small piece of parchment paper.
- In a blender (or using a handheld blender and a deep cup or vessel), puree the sweet potato, 1/2 cup of the water, maple syrup, balsamic vinegar, and vanilla extract until completely smooth.
- In a large bowl, combine the flour, coconut sugar, chocolate chips, and sea salt, then sift in the cocoa, baking powder, and baking soda.
- Add the wet ingredients to the dry (be sure to scrape out all the blended ingredients with a spatula, and use the remaining 1 tablespoon of water to rinse the blender jar and get out any remaining puree).
- Mix until just well incorporated.
- Transfer to the prepared pan, bake for 21–23 minutes, remove, and let cool on a cooling rack.
Frosting:
- Place the sweet potato, coconut sugar, cocoa powder, cashew butter, sea salt, 1–2 tablespoons of the milk, and vanilla extract in a blender or food processor and puree until very smooth.
- It’s best to use a blender or processor (versus a stand mixer) if using orange sweet potato, to fully smooth out the potato.
- Taste, and add more sweetener if desired, and also another 2–3 tablespoons of milk if needed to thin to preferred consistency (you may need more milk using yellow sweet potato as they aren’t quite as moist as the orange).
- Puree until smooth, scraping down the blender/processor bowl as needed.
- Transfer to a container and refrigerate until ready to use on the Sweet Potato Chocolate Cake. Or, get a spoon and dig in!

Carolyn says
This cake is so yummy! Does it need to be stored in the fridge? Thanks!
Dreena Burton says
Hi Carolyn, yes, refrigerate any extra. It won’t hurt if it’s left out overnight first night, but because there are no preservatives, it’s best to keep it in the fridge.
AmyZ says
I’m excited to try this recipe. I will be trying this with all purpose gluten free flour as mentioned in an earlier comment. What do you recommend in place of the vinegar (which I do not use)? I was thinking fresh lemon juice?
Dreena Burton says
Hi Amy, oof, I’m late to reply, sorry! I haven’t tested it with lemon juice, but that would be the best option.
Lisa says
Hi Dreena. This cake looks amazing (and so does the vanilla version!)! I love chocolate and peanut butter. With that in mind, do you think it would work to replace the nut butter in the frosting with peanut butter? I am not sure whether that would come out tasting strange given the sweet potato base.
Dreena Burton says
Hi Lisa, so sorry for my late reply. Thanks for commenting, if you love PB, then go for it! When I developed the recipe, I didn’t want a nut butter flavor to be too prominent, and PB is a stronger flavor. But it will work just fine. Enjoy!
Silvina says
Can I use Oat flor instead of spelt four?
Dreena Burton says
Hi Silvina, I wouldn’t sub in full. You can try, however in my experience using all oat flour can yield a ‘sticky’ or gummy type of texture.
