My cookbook is here! 
This rich and decadent chocolate cake is sweet and smooth like mousse cake. It is made with only 4 healthy ingredients!
This flourless sweet potato chocolate cake is a masterclass in minimalist baking. Requiring only four main ingredients: smooth sweet potato puree, eggs, pure maple syrup, and rich cacao powder.
To be honest, we were skeptical at first mixing vegetables into a cake batter often feels like a gamble, and we truly thought it wasn’t going to come out good. However, those doubts vanished the moment it left the oven.
The preparation is incredibly simple, requiring just one bowl and a few minutes of whisking. Despite our initial hesitation, the result was a perfectly set, velvety cake that defied our expectations.
To finish, the cake is smothered in a rich chocolate frosting made by melting chocolate chips into heavy cream. This silky ganache adds a layer of indulgence that perfectly complements the airy cake.

4 Ingredient Chocolate Sweet Potato Cake
Ingredients
- 1½ cups + 1 tbs (420 g) sweet potato puree
- 2 large eggs, lightly beaten
- 5 tbs maple syrup
- 1/2 cup + 2 tbs (43 g) cacao powder
Optional Add ins:
- 1 tsp vanilla extract
- 1/4 tsp salt
- 1/4 tsp espresso powder
Frosting:
- 1/2 cup (90 g) dark chocolate chips
- 2 tbs heavy cream, room temp
Instructions
- Preheat oven to 350℉. Line an 6 inch round cake pan with parchment paper.
- In a large bowl, whisk together the eggs, maple syrup and vanilla. Next, whisk in the sweet potato until fluffy. Sift in the cacao powder and salt. Mix everything until batter is super smooth, fluffy and has the texture of mousse. Then, transfer to batter to your cake pan and spread out evenly. Tap the pan on your counter a few times to eliminate any bubbles. Bake for about 1 hour.
- VERY IMPORTANT: Allow the cake to set and cool in the pan for at least 2 hours. I personally allow the cake in pan to cool on a wire rack for 30 minutes and then transferred to my fridge and chilled for 2 more hours (or overnight).
Frosting:
- In mini pot, melt your chocolate chips. Transfer to a small bowl and add in the heavy cream. QUICKLY, whisk the two together vigorously until thick and smooth. Spread this out evenly on top of the cake. Shave some chocolate for aesthetic.
Notes
- Nutritional Information includes the chocolate frosting.
- Store leftovers in an airtight container in the fridge for up to 4 days.
- Recipe adapted from Kirbie’s Cravings.Com
- You can use pureed butternut squash or pumpkin instead of the sweet potato.
- You can use honey instead of maple syrup.
- This cake isn’t very sweet by itself , so I definitely recommend making the chocolate frosting.
I Love that this recipe is free from Flour & Sugar. I made it with fresh sweet potatoes. It made beautiful Chocolate Squares. Pretty Yummy!
Hi Lorraine, thank you for trying this cake and I’m so glad you lliked it!
I love how it is made with dark chocolate & sweet potato! I call it Chocolate Squares! It is very Nice that it has no Flour or Sugar
I made this cake a couple of days ago. My partner dislikes sweet potatoes, but I want to include them in our diet, because they are so nutritious. I used boiled and mashed sweet potatoes instead of canned. He really enjoyed this cake. I shared some with our neighbors, and they liked it too. I sent them the recipe. I was so impressed that the cake was delicious without any granulated sugar or flour. I thought it was more like a giant chocolate truffle.
Stella, I really appreciate your recipes and your cookbook is the best I have ever owned. Thank you so much!
can this cake be frozen?
Really good. Next time, less cocoa powder. Definitely a keeper. Thank you
Thanks for trying the recipe and coming back to share your feedback!
Hi, can you use an egg substitute?
HI Lisa, I cant say. I havent tried it with an egg subsitute
I must say that these recipes for 6” cakes are of no use to me. I can see that it would be useful to a couple but for larger families/groups totally useless. I am mathematically challenged and cannot begin to increase this to be baked by me.
Can you do the math?
Hi Angela, there is an option on my site where you can double or triple the recipe. Its in each recipe box on the right hand side. I hope this helps!
Can pureed baked sweet potatoes be used instead of canned? Also can baking coco powder be used in place of the cacao powder?
Hi Deana, yes to both the questions! Enjoy!
