Make Oat Milk at Home

Last Update: July 13, 2023

There are so many possibilities in a simple bag of rolled oats. You can mix up a quick, hot breakfast, stir them into pancake and waffle batters, or grind them down to a powder to make flour. You can also make oat milk at home, that is creamy, plant-based and tastes great. On this episode of Prep School, Megan Mitchell shows you the ropes with this lightly-sweetened sip. We used maple syrup, but you can swap in any sweetener of choice, like date syrup or agave syrup.

  1. Add oats to a medium bowl and cover with water; let sit 20 minutes.

  3. Add oats and water to a high-powered blender, along with salt, maple syrup, and cinnamon (if using).
