Learning how to make oat milk at home starts with steel-cut oats and water, plus optional maple syrup, vanilla and a little coconut oil. My method keeps it silky instead of slimy, and there are no gums or fillers.
Place the oats in a bowl, add just enough water to cover them and soak for 20 minutes. Drain off the soaking water.
Place the soaked oats and the fresh water in a high-speed blender and blend until smooth.
Strain through a nut milk bag or cheesecloth into a wide glass bowl. Discard the pulp.
Rinse the blender and pour the strained milk back in. Add the coconut oil, maple syrup, vanilla and salt, if using, and blend for 10 seconds.
Notes
Texture Tip: Blend just until smooth and use cool water. Overblending or warm water can make oat milk slimy.
Leftovers: Save the pulp for smoothies, baked goods or overnight oats.
Flavor Variations: Sweeten with pitted dates or another natural sweetener instead of maple syrup. For chocolate or berry oat milk, add 2 tablespoons cacao powder or 1/2 cup berries in the final blend.
Storing: Store in a sealed jar in the fridge for up to 5 days. Shake well before using, since it separates.
