Zero Waste Oat Milk

At 99 cents a pound, oats are an incredibly cheap grain. Homemade oat milk costs MAYBE 25 cents a quart. Compare that to the $5 half gallons in stores and tell me that a little extra effort isn’t worth it. I’ve never been a big milk drinker so we typically use oat milk in recipes, for cereal, coffee, or to dip cookies in.

This is a base recipe that can be modified to fit your tastes. If you prefer thicker oat milk, use less water, if you prefer thinner, use more. To add sweetness we throw in a date or two and a dash of vanilla. 

Since this recipe doesn’t include stabilizers, it does separate if it sits in the fridge. Just give it a quick shake before using!

Zero Waste Checklist
  • Find oats in the bulk section of your local grocery store
  • Buy oats in the largest package
  • Save the oat pulp to make crackers, add to smoothies, or make a face mask!
