Homemade Oat Milk

Creamy, Naturally Sweet, and Better Than Store-Bought

In the last couple of years, oat milk has really made a splash—and if you’ve tried it, you know why! To me, it tastes like the delicious milk left at the bottom of a cereal bowl: oat-y, creamy, and naturally sweeter than cow’s milk. While it’s a staple on grocery shelves, making it yourself is surprisingly simple, budget-friendly, and free of any extra additives.

What You’ll Need

• 1 cup Old Fashioned Oats: Rolled oats work best for a creamy texture.
• 4 cups Water: Use cold water to keep the milk from getting “slimy.”
• Sweetener of Choice: 1 pitted date or 1 tablespoon of maple syrup.
• A Pinch of Sea Salt: This helps balance the sweetness and brings out the oat flavor.
• Optional: A splash of vanilla extract for that classic “cereal milk” vibe.

How to Make It

1. Puree: Add the oats, water, sweetener, and salt to a high-speed blender. Blend on high for only 30–45 seconds. Tip: Don’t over-blend! Keeping it quick prevents the oats from getting too warm and gummy.
2. Strain: Place a clean T-shirt or a thin kitchen towel over a bowl. Pour the mixture through and gently squeeze to separate the milk from the pulp.
3. Bottle It: Pour the liquid into an airtight container or glass jar.
4. Chill: Store in the refrigerator for up to 5 days. Give it a good shake before each use, as natural separation is normal!

Get the Kids Involved

Making milk from scratch feels like a kitchen science experiment that kids love to help with.

• Ages 3–5: Let them help “squeeze” the cloth to see the milk come out. It’s a fun, tactile activity!
• Ages 6–9: Have them help choose the flavor. Will it be Strawberry Oat Milk (blend with a few strawberries) or Chocolate Oat Milk (add a spoonful of cocoa powder)?
• Ages 10+: Let them take charge of the “Shake Test.” Since homemade milk separates, they can be the official jar-shaker before breakfast.

Make It Weeknight-Friendly

• The “No-Soak” Rule: Unlike almond milk, you do not want to soak your oats beforehand. Soaking makes the final product slimy. Just dump and blend!
• Strain Like a Pro: Avoid using a cheesecloth, as the weave is too loose. A fine-mesh T-shirt or a nut milk bag is the secret to a silky-smooth finish.
• The Pulp Hack: Don’t throw away the leftover oat pulp! You can stir it into your morning oatmeal or add it to a batch of muffin batter for extra fiber.
• Flavor Riffs: If you’re feeling fancy, blend in a teaspoon of matcha powder for a vibrant Matcha Oat Milk latte to kickstart your afternoon.

Serve & Savor

Use your homemade oat milk in your favorite Smoothie Project recipes, pour it over granola, or enjoy a cold glass on its own. It’s a simple, nourishing habit that makes the whole family feel a little more connected to the food they’re eating.
