Prepare the base: Begin by pouring 1 cup of unsweetened almond milk into your blender to act as a light, creamy base for the smoothie.
Add macadamias: Drop in 2 tablespoons of soaked macadamia nuts; soaking will make them blend easily and add a creamy, nutty flavor to the drink.
Add flavor: Add richness and depth by pouring in 1 teaspoon of pure vanilla extract and 2 tablespoons heavy cream (use coconut cream to keep it dairy-free).
Sweeten to your taste: Put about 1 tablespoon of keto-friendly sweetener into it, like stevia or erythritol and then adjust based on how sweet you want your smoothie.
Blend with ice – Toss in 4–5 ice cubes and blend everything until silky smooth with no nut chunks left. Pour into a glass, serve chilled, and enjoy immediately.
