  • Plant-based milk: Almond, soy, oat, cashew, and coconut milk are all good options.
  • Maple syrup: This liquid sweetener adds sweetness but you can also use date or agave syrup.
  • Oat flour: Makes a great base in this sweet potato cake recipe and holds everything together.
  • Cocoa powder: Go for unsweetened cocoa powder for the best flavor.
  • Cinnamon: Adds a hint of spice that works great with the vegan chocolate and sweet potato.
  • Baking soda and salt: For flavor and texture.
  • Vegan chocolate chips: Adds more rich chocolate flavor.
  • Chia seeds and crushed almonds: Both ingredients are optional but they do boost the nutrition and add a bit of texture to the cake.

How To Make Vegan Sweet Potato Cake

Once you get the sweet potatoes cooked, it’s super easy to make this vegan chocolate loaf cake.

Preparation Steps:

  • To get started, preheat the oven to 400 degrees F and boil the diced sweet potatoes in boiling water in a saucepan for 15 to 20 minutes or until fork-tender.

Step 1: When the sweet potatoes finish cooking, remove the skin and puree in a blender or food processor until smooth.

Step 2: After that, combine the sweet potato puree, plant-based milk, and maple syrup in a large mixing bowl and mix together. Next, add the oat flour, cocoa powder, cinnamon, baking soda, salt, and vegan chocolate chips. If you are using the chia seeds and almonds add them in at this time.

Step 4: Place the dough in a greased loaf pan and bake in the oven for 35 to 40 minutes or until a fork comes out clean and the top is hardened a bit. Finally, remove from the oven and allow the vegan chocolate loaf cake to cool completely! Optional but recommended: drizzle with nut butter of your choice!

Toni’s Recipe Tips for Vegan Loaf Cake

  • Want a fudgier loaf? Underbake the vegan sweet potato cake slightly. 
  • Serving this vegan sweet potato cake. It tastes even better topped with your favorite nut butter.
  • Store in the refrigerator. The sweet potatoes in this recipe mean leftovers need to be stored in the refrigerator.

FAQs for Chocolate Sweet Potato Cake

Can I bake or roast the sweet potatoes instead of boiling them?

Yes and no. If you prefer to bake the sweet potatoes whole instead of boiling, it works great. But it does take longer. I don’t recommend roasting cut sweet potatoes as they may develop crispy edges that won’t blend up smooth. Although baking sweet potatoes does retain more of the nutrients than boiling them.

Can I keep the skins on the sweet potatoes?

I recommend not, as the skins will not puree as smoothly, affecting the texture of the cake.

Variations on a Sweet Potato Loaf Cake

  • Swap the sweet potatoes. If you don’t have sweet potatoes, try some pumpkin!
  • Bake muffins instead! Pour the batter into a muffin tin and decrease the baking time to 12-15 minutes.
  • Add some walnuts. Instead of almonds or chia!

    Made this for the first time yesterday, and LOVED it! Great texture and taste, this recipe is definitely a keeper in my dessert rotation 🙂

  2. What size serving does this recipe for sweet potato cake have 34 g of carbohydrates? I need to watch my carb intake,

    1. Hi! We at Plant-Based on a Budget haven’t tried that out yet so can’t guarantee the results of either so please let us know how it turns out if you do 🙂

      1. I’ve sub’d almond four for the oat flour with a 1:1 ratio and the recipe turned out great. A little more dense than when I used oat flour, but no difference in taste that I could tell. Still delicious!

  3. OOOOH! I will be making this recipe but I will probably add chopped ginger. Also, staying with sweet potato recipes, I think a vegan cream cheese frosting made from white sweet potatoes (lemon juice, maple syrup, etc) would complete the package.

  4. 5 stars
    This loaf is absolutely perfect! I love desserts with veggies! Perfect way to add additional nutrients to your diet!

  5. 5 stars
    I love sweet potatoes but have never thought of using them to make chocolate cake. I’m always looking for healthy versions of my favourite foods that don’t compromise on taste or texture so this is perfect!

    This was my first time using sweet potatoes in a cake so I was a little skeptical but it totally works! Delicious and the texture is spot on. 🙂

  7. I’ve been loving sweet potatoes lately and this chocolate cake did the trick! So sweet and delicious!
