Soak nuts the day before or use almond butter.
Put a litre of water in a blender and add about a cup soaked nuts or 1/2 cup of almond butter.
Add a banana, 1/2 teaspoon vanilla powder and 2 tbsp coconut sugar.
Pour into straining bag and squeeze out liquid if using whole nuts. If using nut butter there is no nut pulp to strain out.
