There is the dates and maple syrup in the homemade Nutella, but we also added a banana to the Nutella smoothie because not only will that appeal to those with a sweet tooth, but it makes it nice and thick too.u003cbr/u003eI don't think it tastes overly banana-y, but I know some people really hate the taste so you might want to leave it out. You should replace the thickness though, u003cstrongu003eso add some avocado insteadu003c/strongu003e.u003cbr/u003eYou could use something like mango, but it does have a strong flavour.
