I recently discovered how to make a smoothie taste like a dessert; you add 1tbs of silan and 1tbs of cashew paste. 
  
About silan, silan is light, complex, and smooth in texture with a sweet flavor that lies between maple syrup and honey.    It's made from pressed dates, mainly Medjool dates. I love to put it in smooties where it's essencial fruit is banana or mango, but it goes well with every type.
