Ingredients Method Notes

Ingredients
  

  • ½ cup rolled oats
  • ¾ cup milk of choice dairy, almond, oat, or soy
  • ½ cup Greek yogurt
  • 1 scoop vanilla protein powder
  • 1 tbsp chia seeds or ground flaxseeds
  • 1 tbsp peanut butter or almond butter
  • 1 tsp honey or maple syrup optional
  • Pinch of cinnamon
  • Fresh fruit or nuts for topping

Method
 

  1. Add rolled oats, milk, Greek yogurt, and protein powder into a jar or bowl.
  2. Mix in chia seeds, peanut butter, cinnamon, and honey/maple syrup if you like sweetness.
  3. Stir well until everything is smooth and combined.
  4. Cover with a lid or wrap and refrigerate overnight (at least 4 hours).
  5. In the morning, stir again, add your favorite toppings like fresh fruit or nuts, and enjoy cold.

Notes

  • If you don’t have protein powder, just use more Greek yogurt for extra protein.
  • Overnight oats last 3–4 days in the fridge, so you can make a batch ahead of time.
  • Add toppings right before eating so they stay fresh and crunchy.
