Blend Hazelnuts: Place roasted hazelnuts or hazelnut butter in a high-speed blender and blend until they become smooth. This is your nutty smoothie base.
Add Cocoa & Sweetener: Whisk in unsweetened cocoa powder and sweetener of choice. This does the trick for rich, chocolatey Nutella flavor without sugar.
Pour in Liquids: Stir in unsweetened almond milk, heavy cream, and vanilla extract. Those three ingredients make the smoothie light and super creamy.
Add Ice Cubes: Add a few ice cubes to cool and adjust the consistency, for that chilled experience.
Blend Smoothly: Mix well until you get a smooth and silky consistency.
Serve & Enjoy: Pour into a glass, garnish with more whipped cream or crushed hazelnuts if desired and enjoy while fresh.
