You can make blue milk at home without using refined sugar or artificial food dyes. It's perfect for a Star Wars-themed birthday party or anytime you need a naturally blue drink.
In a high-speed blender, add the white grape juice, milk, coconut milk, pineapple, and blue spirulina powder. Secure the lid and blend until the mixture looks smooth and creamy. (And bright blue!)
Pour the blue milk over ice, and it's ready to serve right away. I recommend serving this with a straw for stirring and sipping, as the blue milk can separate if left to sit for too long.
Notes
Nutrition information is for 1 of 6 servings, or approximately 2/3 cup. (Assuming you get 4 cups total from this recipe.) This information is automatically calculated, so it's just an estimate and not a guarantee. Coconut Milk Note: I recommend blending the can of coconut milk before measuring it for this recipe. Some cans will have a lumpy texture at first, as the cream and liquid separate, so blend it for 60 to 90 seconds, or until the milk looks smooth and creamy. (There should be no lumps floating on top; if there are, blend the milk longer.) Milk of Choice: I tested this recipe with unsweetened soy milk, but Disneyland's version is reportedly made with rice milk. Feel free to use any plant-based milk you enjoy for a dairy-free recipe that's vegan-friendly. Or use cow's milk if you don't need a dairy-free recipe. Straining (Optional): If you don't think your blender fully pulverized the pineapple, you can pour the milk through a fine mesh strainer to catch any pieces of pineapple that might have been missed. There shouldn't be much! Blue Spirulina: I buy blue spirulina on Amazon.
