What is oat milk?

Oat milk is a popular alternative to non-dairy milk made from oats. It’s super creamy, super easy to make and tastes amazing. It also uses simple and inexpensive ingredients. You only need two main ingredients to make oat milk: oatmeal and water. From there, you can add additional ingredients to really customize the oat milk. We have made suggestions below.

Make your own oat milk from scratch

Once I realized how easy it is to make oat milk, I found myself making it on a regular basis. Whenever I’m baking and realize I don’t have regular milk or other plant-based milk, homemade oat milk is my hero!

  1. Place 1 cup oatmeal and 4 cups cold water in a blender. You can also add optional toppings like maple syrup or a pinch of salt, see recipe for our tips.
  2. Blend for 30 to 45 seconds.
  3. Strain through a nut bag, clean cotton cloth, or several layers of cheesecloth.
  4. For best results, strain the oat milk a second time.

Frequently Asked Questions

How can I keep my homemade oat milk from getting slimy?

The starch in oats can help make homemade oat milk gooey. This is exactly what we do to minimize viscosity:

  • Use cold water when mixing.
  • Do not soak oatmeal.
  • Don’t blend the oats for too long. Stick to 30 to 40 seconds.
  • Strain the oat milk, which removes excess starch (the main cause of sticky oat milk). In fact, we prefer to filter twice.

Can I add sweeteners or flavorings like berries or chocolate to the oat milk?

Absolutely! For a slightly sweetened oat milk, add some maple syrup or honey. You can also add a pinch of salt to balance out the flavors.

  • For berry flavored milk, add fresh or thawed frozen berries.
  • For the chocolate oat milk, add a tablespoon or two of cocoa powder.

Should I use oatmeal to make oat milk? Will instant or steel cut oats work?

For best results, we recommend using oatmeal to make oat milk. Instant oatmeal is more processed and runs the risk of being sticky oat milk. Steel rolled oats are more difficult to mix and do not make the oat milk as creamy as rolled oats. You can use these in a pinch, just make sure your blender is super powerful.

Why has my oat milk separated? Is it ruined?

Don’t worry, some breakups are perfectly normal. Simply stir or shake the milk before use.

Does homemade oat milk foam?

Unfortunately not. Store-bought foaming oat milk has some extra ingredients (like stabilizers) that help it foam and heat up without becoming sticky.

How to Make Oat Milk (Very Easy!)

Oat milk is a creamy and delicious plant-based milk that requires only a few ingredients and about five minutes of preparation time. Use oat milk to replace cow’s milk in baked goods, add to smoothies, coffee or pour over your favorite cereal.

Makes about 3 cups

will need

oat milk

1 cup oatmeal

4 cups of cold water

optional ingredients

1 pinch of salt

1 to 2 tablespoons maple syrup

1/2 to 1 teaspoon vanilla extract, for the vanilla milk

2 tablespoons cocoa or cocoa powder for the chocolate milk

A handful of berries, for the berry milk


    In a blender, combine oats and cold water along with any optional ingredients. Cover with a lid and blend for 30-40 seconds. It’s okay if you see small oatmeal. It’s best not to mix too much as this can result in a slimy texture.

    Strain the oat milk. This works best with a bag of nut milk, a clean cotton tea towel, or several layers of cheesecloth placed over a large bowl or pitcher.

    For best results, double strain the mixture to remove most of the solids.

    Store homemade oat milk in an airtight container and refrigerate for up to a week. Shake or stir before use.

Advice from Adam and Joanne

  • Gluten-Free: Not all oatmeal is certified gluten-free. If you are sensitive to gluten, make sure the oats you use are gluten-free.
  • Steel cut oats don’t produce milk as creamy as rolled oats, but it will work. For best results, use a powerful blender. We don’t recommend using instant oatmeal as it’s already processed, which adds more starch to the milk (risking a slimy texture).
  • Nutritional Information: The nutritional information below is an estimate. We use the USDA database to calculate approximate values.
