Add the liquids: Pour 1/2 cup unsweetened coconut milk and 1/2 cup unsweetened almond (or macadamia) milk into the blender.
Add the nuts: Add 1/4 cup raw, unsalted macadamia nuts.
Flavor it: Add 1 to 1 1/2 teaspoons vanilla extract, 1/8 teaspoon cinnamon, and a small pinch of sea salt.
Sweeten to taste: Start with 1 to 2 teaspoons of your preferred keto sweetener.
You can always add more after blending.
Ice it: Add 1 to 1 1/2 cups of ice, depending on how thick you like it.
Boost if you want: Add 1 scoop collagen peptides or 1/2 scoop unflavored whey isolate for protein. Add 1 teaspoon MCT oil if desired.
Blend until silky: Blend on high for 30–45 seconds, until completely smooth and creamy. Scrape the sides if needed and blend again.
Taste and adjust: Check sweetness and thickness.
Add a splash more milk to thin or a few ice cubes to thicken. Add a touch more sweetener if needed.
Serve right away: Pour into a chilled glass. Sprinkle a little cinnamon on top if you like.
