Moist chocolate cake with creamy chocolate filling, obviously there is not a better combination for a birthday cake, and this is the third year in a row that I make this recipe to celebrate mine! And I also made it for my girlfriend’s birthday the past year, I’m totally obsessed with it.

And although it seems incredible, this cake is super healthy, a large percentage of this cake is sweet potato, both in the sponge cake and in the filling, although used in different ways.
The filling contains cooked sweet potato, processed with melted dark chocolate, honey or maple syrup as a sweetener, cacao to achieve that intense chocolate flavor and melted coconut oil, to achieve a good consistency. This filling really taste like chocolate ganache super creamy and very delicious.
And the sponge cake has sweet potatoes, raw, peeled, chopped, and processed until minced, which we will use as the main ingredient along with coconut flour, cacao, eggs or egg replacements for a vegan recipe, oil and muscovado sugar. Once mixed everything, we will divide the mixture into the molds and bake it, taking care that the cake does not dry, leaving it moist, thus obtaining a super moist cake with a creamy filling that melts in the mouth in a chocolate explosion.

The recipe is super easy and simple, perfect for any time you crave a decadent chocolate cake but still healthy.
And if you want to take it to the next level, as I did in this case, you can add coffee to the filling, a shot of espresso is enough to make you feel the rich aroma of coffee, which combines perfectly with chocolate.
