Description

Learn how to make oat milk with protein right from your own kitchen for a budget-friendly, nut free, dairy free, and gluten free milk alternative perfect for all your needs!


Ingredients

Units Scale
  • 1 cup gluten free old fashioned rolled oats
  • 45 cups purified water, cold (See notes) – the less you use the thicker the milk
  • Pinch of sea salt
  • 2 Tablespoons maple syrup or 3 pitted dates

Optional Flavor Mix-Ins: 

  • 1 frozen banana, sliced
    1 Tablespoon unsweetened cocoa powder
    1/3 cup fresh berries
    2 Tablespoons coconut butter or sunflower butter (to make extra creamy)

 Optional Protein Boosters: 

  • 23 scoops (1625 grams) collagen or vegan collagen (unflavored/vanilla/chocolate/etc.)

Instructions

  1. Place the rolled oats and purified water in a blender. Blend on high speed for 30 seconds or until they are broken down into a very fine meal. NOTE -> Blending too long will warm the oats, creating a slimy texture. 
  2. Add sweetener of choice (if using) and salt, and blend again. 
  3. Place a layered cheesecloth or a fine mesh bag in a colander that has been set inside a large bowl. Pour the blended oat mixture over the cloth. Let the liquid drip through. Do NOT squeeze the excess oat pulp through the strainer! This will create a gummy texture. 
  4. If adding sweeteners and flavor mix-ins, place the strained oat milk back in the blender and blend until creamy. For fruit-flavored mix-ins, strain once more to remove any seeds or flesh. If adding protein (collagen), whisk or blend it into milk after sweetening. (See notes)
  5. Divide the milk into mason jars or one large glass jar. Cover and let the oat milk chill for 6-12 hours before using.
  6. Refrigerate for up to 5 days.

Notes

As the protein oat milk sits in the fridge, a small layer of film or separation will rise to the top. This is natural. Just give it a good shake before using it!
