Notes
Yield: This recipe makes about 6 cups of oat milk. The recipe is easily doubled.
Rolled, old-fashioned oats are best. Avoid quick-cooking or instant oats, which can lead to slimy oat milk. To ensure this oat milk is gluten-free, use certified gluten-free oats.
Be sure to use iced water for this recipe for the best results.
If you don't have a large blender, you can blend it in batches in a smaller one.
Storage: Store oat milk in an airtight container in the refrigerator for up to 5 days.
