It’s a sin not to have a birthday cake on your birthday, but when you’re trying to eat clean it isn’t exactly part of a healthy diet and we know we ought to say no.

My birthday is looming, and as a self-confessed chocoholic, I decided to create an indulgent chocolate cake minus the preservatives, sugar content, and other added nasties.

This cake is free of refined sugar, dairy, wheat and gluten! On top of that, it tastes amazing and you won’t have to miss out on a slice of birthday cake after all.
