This recipe for overnight oats without milk or yogurt is an easy make-ahead breakfast.  Whether you don’t have milk or don’t want to use it, here is how to make overnight oats with water.  


  • 1/2 cup old-fashioned oats
  • 1/2 cup water
  • 1 tablespoon ground flaxseeds
  • 2 teaspoons maple syrup, or to taste
  • 1/2 teaspoon ground cinnamon, optional


  1. In a jar or container with a lid mix together the rolled oats, water, ground flaxseeds, maple syrup, and ground cinnamon if using.
  2. Add any flavor options while preparing the oats.
  3. Let them soak for at least 2 hours for the oats to soften, but overnight is best.
  4. Top with toppings and enjoy!


See the blog post for options to make the oats creamy, flavor options, and toppings.

If you prefer a thinner consistency for your overnight oats then add a splash of water.

Cocoa powder, protein powder, and powdered peanut butter will thicken the oats.  You may need to add more water to thin out.  For protein powder, I have to add a lot more water.

Adjust the maple syrup to suit your preference for sweetness.
