This Sweet Potato Chocolate Cake is seriously moist, super chocolatey and definitely doesn’t taste like vegetables! It’s also vegan and gluten-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!
Why you’ll love this Sweet Potato Chocolate Cake:
- it’s undetectably vegan and gluten-free
- it’s seriously moist
- it’s super chocolatey
- it doesn’t taste of vegetables
- it’s secretly healthy
- it’s perfectly sweet
- it’s a source of protein and fibre
- it’s refined sugar free
- it’s super easy to make
- it’s filling and satisfying!
