Creamy, naturally sweet, and incredibly easy to make, this Homemade Oat Milk is a simple plant-based alternative the whole family will love. With just a few pantry ingredients and a blender, you can create fresh oat milk at home that’s perfect for smoothies, coffee, cereal, or baking.

Ingredients

Scale

Yield: About 3½ cups

  • 1 cup old-fashioned oats

  • 3½ cups water

  • 1 pitted date or 1 tablespoon maple syrup

  • ¼ teaspoon vanilla extract (optional)

Instructions

  1. Blend the Oats
    Add oats and water to a high-speed blender. Blend for 30–45 seconds, or until the oats are mostly pulverized. Small oat pieces are perfectly fine.

  2. Adjust Sweetness
    Taste the mixture. If you prefer a sweeter milk, add another pitted date or a little more maple syrup and blend for an additional 15 seconds.

  3. Strain the Milk
    Place a clean white T-shirt, nut milk bag, or kitchen towel over a pitcher or large bowl. Slowly pour the blended mixture through the cloth.

  4. Squeeze and Extract
    Gently squeeze the cloth to extract as much oat milk as possible.

  5. Store
    Transfer to a sealed container and refrigerate for up to 5 days. Shake well before using.

Notes

Texture Tips

  • Avoid over-blending, which can make oat milk slimy. Blend just until oats are broken down.

  • Strain gently — excessive squeezing can also affect texture.

Flavor Variations

  • Strawberry Milk: Add ¼ cup fresh or frozen strawberries during blending.

  • Chocolate Milk: Add 2 tablespoons cocoa powder.

  • Matcha Milk: Add 2 teaspoons matcha powder for a green tea version.

Best Uses

  • Coffee and lattes

  • Smoothies and shakes

  • Overnight oats or cereal

  • Baking recipes

Storage

  • Natural separation is normal — shake before serving.

  • Store in a glass container for best freshness.
