This Sweet Potato Chocolate Cake is seriously moist, super chocolatey and definitely doesn't taste like vegetables! It's secretly healthy, perfectly sweet, and super easy to make. It's vegan, gluten-free and refined sugar free.

My Chocolate Banana Bread recipe has been super popular, but I've had a lot of people asking me how to replace the bananas...so I decided to make a similar recipe using sweet potatoes instead of bananas.
Sweet potatoes work as an excellent alternative to bananas as they have a similarly naturally creamy texture and high natural sugar content. Plus I know from making recipes like my Sweet Potato Chocolate Buttercream Frosting, Chocolate Sweet Potato Ice Cream, Sweet Potato Brownies and Chocolate Pie that sweet potatoes can absolutely be used in desserts, and chocolate definitely masks the taste!
How to make this recipe
Scroll down to the bottom of the post for the full recipe.
- Place the cooked sweet potatoes and plant-based milk in a food processor.
Tip: Use a measuring jug to measure out the plant-based milk.
- Whizz until completely smooth.
- Mix with all the other ingredients in a glass mixing bowl.
- Transfer the mixture into a one-pound loaf tin.
Tip: Line the tin with greased baking paper to make it easier to remove the cake afterwards.
- Scatter over more chocolate chips to decorate, if desired.
- Bake in the oven for around 45 minutes, until an inserted skewer comes out clean.
Tip: Leave the cake to cool down on a cooling rack before putting it away to store, to make sure it doesn't get soggy!
How long does this keep for?
It does taste best when fresh, but keeps covered in the fridge for up to a few days.
Substitutions you can make

- You can use any type of plant-based milk: almond milk, rice milk, soy milk, cashew milk, oat milk etc.
- You can use any type of liquid sweetener: maple syrup, agave syrup, brown rice syrup etc.
- You can replace the ground almonds (almond meal/almond flour) with ground walnuts.
- For a nut-free version: replace the ground almonds (almond meal/almond flour) with ground sunflower seeds and use a nut-free plant-based milk.
- You can use plain flour, wholemeal (whole wheat) flour or spelt flour instead of the gluten-free flour if you’re not gluten-free.
- You can omit the chocolate chips.
- For a refined sugar free version, omit the chocolate chips or use refined sugar free chocolate chips or chunks.

- To make a more decadent cake, don’t scatter over the chocolate chips before baking, and instead cover the cake with my Vegan Sweet Potato Chocolate Buttercream Frosting!

I'm just curious, the recipe calls for almond 'meal' as opposed to flour - but the link leads to almond flour. I have both, which should I use? Love your recipes. Looking forward to making this one, too.

You can use either!

Hi Rhian,
I am going to try this for my sons 3rd Birthday party and am going to do a test run ahead of time for his actual birthday rather than the party. I am wondering if I can make it on Sunday for Thursday night, and if I should freeze it?
I'll make it again nice and fresh for the party.
It was actually recommended to me by a friend who made it and loved it so I am excited to try.
Thanks, Bridget

Thank you so much! You can make it on Sunday for Thursday night and freeze it as soon as it's cool then defrost before eating. I hope you'll like it, please let me know if you have any more questions!
