Ingredients Method Notes

Ingredients
  

  • 1 medium (about 120 g) frozen banana, cut into chunks must be frozen for thick texture
  • 30 g roasted hazelnuts pre-roasted, skins on or off both fine
  • 1 tbsp dark cocoa powder Dutch-process preferred
  • 200 ml oat milk plus up to 50 ml more if needed
  • 1 tbsp hazelnut butter optional, intensifies nut flavor
  • 1 tsp maple syrup optional, adjust to taste
  • 1 small pinch sea salt

Method
 

  1. Add the roasted hazelnuts to the blender and blend alone on high for 20-25 seconds until finely ground and no large pieces remain.
  2. Add the frozen banana chunks, dark cocoa powder, hazelnut butter (if using), maple syrup (if using), sea salt, and 200 ml of oat milk.
  3. Blend on high for 45-60 seconds until completely smooth and creamy. If the blender stalls, add oat milk in 2 tablespoon increments until it moves freely.
  4. Taste and adjust. Add a touch more maple syrup for sweetness or a little more cocoa powder for a deeper chocolate flavor.
  5. Pour into a wide glass. Top with a few roughly chopped hazelnuts and a light dusting of cocoa powder. Drink immediately for the best texture.

Notes

For the smoothest texture, always pre-blend the hazelnuts before adding any liquid. This one step prevents the gritty finish you often get with nut-based smoothies.
