Toppings (optional)

  • ¼ cup raspberries
  • ½ Tablespoon peanut butter
  • ½ teaspoon cacao nibs


  • In a medium bowl, mash the banana until there are no large chunks. Add the oats, powdered peanut butter, flax, hemp seeds, vanilla, and salt and stir until combined.
  • Add the soy milk and stir until no lumps or dry spots remain.
  • Divide the mixture evenly between three jars. Cover and refrigerate at least 4 hours, but preferably overnight.
  • The next morning, either heat up the oats before adding the optional toppings, or just add the toppings and enjoy the oatmeal cold. This can be eaten straight out of the jar if you have room to add the toppings, or served in a bowl if you need more room.


Notes: The soy milk contributes 3.5 grams of protein to each serving of oatmeal, so replacing it with another unsweetened high-protein plant milk like Ripple pea milk would be your best bet if you want to keep the protein content on the higher end. If you’re less concerned about protein, you can use another unsweetened non-dairy milk, like almond or oat milk.
Nutrition information is for one serving with toppings.
