In case you missed it – my new cookbook, Love & Lemons Every Day, came out this past Tuesday. It’s been so fun to see it out into the world! If you tagged me on Instagram, thank you, I love seeing your creations! Today we’re celebrating with chocolate cake!! This happens to be a vegan cake, but I promise you’ll love it whether you’re vegan or not.
About This Vegan Chocolate Cake
This may be the healthiest cake I’ve made, but you’d never know it by eating it. It’s perfectly moist with a rich dark chocolate flavor that’s made even richer with a thick layer of vegan chocolate frosting on top.
Secretly, though, this vegan cake is made with half whole wheat flour, and I use maple syrup in place of refined sugar. But the biggest secret of all is in the frosting, which is made from baked sweet potato! As you blend the frosting together, the heat of the sweet potato melts chocolate chips into a smooth puree that’s finished with coconut oil and cocoa powder. While it may feel decadent, this luscious frosting actually gets its wonderful texture and some of its sweetness from a vegetable!
Vegan Cake Variations
In the book, I make this recipe as a layer cake. I love serving it that way for big gatherings or parties, but this week, since Jack and I were celebrating together, I opted for a smaller version. I halved the recipe and baked it in an 8×8-inch square pan, which worked out perfectly for us. I’m sharing that recipe – the halved version – below. To make a layer cake, double it and divide the batter between two round 8 or 9-inch cake pans. Alternatively, if you’re serving a crowd and you’re not in the mood for a layer cake, double this and bake it in a 9×13-inch pan!
And if you prefer white frosting on your chocolate cake, the frosting from this vegan carrot cake recipe would be delicious here.
If you love this vegan cake recipe, please let me know in the comments! Then, try this pumpkin cake, this chocolate zucchini cake, or this banana bread next.

- 1 large sweet potato (enough to yield ¾ cups mash)
- ¼ cup plus 2 tablespoons semisweet chocolate chips
- 2 tablespoons unsweetened cocoa powder
- 1 tablespoon melted coconut oil
- pinch of sea salt
- ¾ cups all-purpose flour
- ½ cup whole wheat flour
- ½ cup unsweetened cocoa powder
- 1 teaspoons baking soda
- ½ teaspoon sea salt
- ¼ teaspoon cinnamon
- 1 cup almond milk
- ¾ cups maple syrup
- ¼ cup extra-virgin olive oil
- 1 teaspoons apple cider vinegar
- 1 teaspoons vanilla extract
- Supernatural Starfetti sprinkles, optional
- Make the sweet potato frosting: Preheat the oven to 425°F. Use a fork to poke a few holes into the sweet potato. Place on a baking sheet or on a piece of foil and roast until very tender, about 60 minutes. Let the potatoes cool slightly, then measure ¾ cups of the soft flesh. In a (small) food processor, puree the sweet potato, chocolate chips, cocoa powder, coconut oil, and salt. The heat of the sweet potato will melt the chocolate.
- Make the cake. Reduce the oven heat to 350°F and grease an 8x8 baking pan.
- In a large bowl, stir together the flours, cocoa powder, baking soda, salt, and cinnamon. To the same bowl, add the almond milk, maple syrup, olive oil, apple cider vinegar, and vanilla. Stir until combined.
- Pour the batter into the prepared cake pan and bake for 25 to 30 minutes, or until the top of the cake springs back when pressed or a toothpick inserted in the center comes out clean. Place the pan on cooling racks and cool for 10 minutes.
- Gently loosen the sides of each cake with a knife. Remove the cakes from the pan and place back on the racks to cool completely. Frost the cake and serve!
This chocolate cake looks so delicious and I would never have guessed it’s vegan. Can’t wait to try this recipe ♥
Is the frosting sweet? It looks like it doesn’t have sugar in it.
It is! There’s sugar in semisweet chocolate chips and also natural sugars in the roasted sweet potato!
It is sweet but if you wanted to make it sweeter you could add more chocolate, or a little milk chocolate too or just a drizzle of maple syrup? I also add a little vanilla
Wow..love this one. Amazing. Keep Glittering, love TGA by Misha ❤️😘👍
This cake looks delicious! I have yet to find the perfect vegan cake recipe as mine always seem to fail! x

Hi! I got your cooking book and baking the chocolate cake right now. I made the frosting and it is absolutely tasty, but turned rather dark compared to yours. I used semisweet chocolate chips. Does it matter which kind of sweet potatoes are used? Thank you!
It’s pretty brown and dark and chocolatey… I photographed it next to a window so maybe it’s just the light reflecting that you see. I hope you like the cake!
This post was so timely. It’s my husband’s today and I was looking for a nice, simple, vegan chocolate cake to make. I made it this morning, sneaked a piece to taste before serving it tonight. It’s really delicious and you’d never know it’s dairy free! This is a keeper! Thank you!
Can you substitute soy milk for the almond milk?
I’m chocoholic and always search new chocolate cakes recipes but I must say this cake looks so spectacular and wait to try this.
This cake looks absolutely delicious! I love those sprinkles on top 🙂
Sweet potato to make vegan frosting?! Brilliant! I always struggle with how to make a solid vegan “buttercream” and it feels impossible. I have to try your method immediately. (Vanilla frosting would be a struggle just because of the color, but maybe I can get away with a white sweet potato? I have to try all of this right now…) I just feel like you’ve gifted me a revelation. Thank you!
Ha, yeah I don’t know if it’ll work as vanilla – the chocolate really masks the vegetal flavor of the sweet potato.
This looks and sounds delish! This is perfect for my daughter’s 2 year birthday! I was looking for a healthy yet decadent alternative. Two things:
1) Can I substitute oat milk for almond?
2) Does roasting the sweet potatoes affect the taste? Could I just steam them instead until soft enough to puree?
Hi Ela, yep, oat milk should work fine, and as long as the sweet potato is soft enough to puree steaming it should be fine!
Hi! This cake looks unbelievable and I’m literally drooling over here. I have a question, can I make the cake and frosting a day in advance and just frost it the day I serve it? Or should I prepare everything, frost it and put it in the fridge? Thank you!
Hi Hannah, it’ll work either way – if you frost it, leave it at room temp, covered. I hope you love it!
i love sweet potato and making the frosting out of it seems very yummy. i am definitely going to give this a try. thanks for this recipe.
chocolate cakes are always one of the best dishes and your looks absolutely delicious
Fantastic chocolate cake recipe! All in one bowl and relatively healthy (for cake!) so I make it with my toddler all the time, it’s super easy!
We aren’t vegan and I’m scared to make a cake without eggs for fear of it being too heavy, so I add three and it’s bouncy and moist and delicious! But I really do need to try making it without!
oh, ha ha, I’m glad you all loved it! It rises really well without eggs too :).
This was terrific! Doable and delicious – my new chocolate cake go to. Thanks so much!
I’m so glad you loved it!
I must try Vegan Chocolate Cake at home.
Vegan chocolate cake look vrey yummy. Your cooking is great. Thanks for sharing.
