Say hello to the best vegan chocolate cake. It's moist & deeply chocolatey, with a rich chocolate frosting made from a secret ingredient: sweet potato!
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.

Vegan Chocolate Cake
- 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!
