Step 1

Place oats into blender with 2 cups cool water. Blend at high speed for 30-60 seconds. Don't blend too long if using a high-speed blender because it will heat the liquid and the oat milk will become too thick and gooey.

Step 2

Place nut milk bag or layers of cheesecloth in a measuring cup. Pour the oat and water mixture into the bag. Gather edges or pull string of bag and suspend over the measuring cup to strain the liquid from the solids. Gently squeeze or twist the bag or cloth to remove as much of the liquid as possible. Discard the oat pulp or save for another purpose. (See notes for ideas.)

Step 3

Rinse out blender to remove any of the oat residue. Pour the oat milk into the blender along with desired flavorings or additions. Blend for 30-60 seconds until well-combined. Transfer to a container or jar with tight-fitting lid. Store in refrigerator for 3-4 days. If the creamer looks bubbly and smells sour, discard.

Step 4

Shake well before using. The creamer will separate into a thicker cream and a thinner, watery liquid. It doesn't mean the creamer is spoiled.
