Add all of your ingredients into a blender. Mix for 1 minute or until the Nutella is mixed in well.
Add Nutella to your serving cup or drizzle some chocolate syrup on the inside (this is optional). Pour all of the frappe into the cup and enjoy. Buen provecho!
Notes
Heavy cream- In this case, the heavy cream is needed so your frappe can thicken. You can leave it out, but you won't get the same texture.
Blender- If you can, it is best to use a blender with a small cup. This is because it will be easier to pour all the frappe from a smaller cup.
Toppings. You can use Ferrero or Kinder Bueno chocolates to add some texture to the drink, but also as toppings.
Frappuccino. You can make this into a frappuccino just by adding ½ teaspoon of instant coffee.
