# Directions:

07 - Seal the container and refrigerate for at least 4 hours, preferably overnight for 8-12 hours

# Expert Hints:

01 -
  • You wake up to breakfast thats already made, creamy, and ready to eat cold or slightly warmed.
  • The combination of oats, Greek yogurt, and protein powder keeps you genuinely full for hours without any mid-morning crash.
  • Its endlessly customizable with whatever fruit, nut butter, or toppings you have on hand, so it never gets boring.
02 -
  • The first time I made these, I didn't stir well enough and ended up with a layer of dry oats at the bottom and a puddle of liquid on top, so mix thoroughly and scrape the sides.
  • Using too little liquid makes the oats stiff and gummy, so don't be afraid to add an extra tablespoon or two of milk if the mixture looks thick.
  • Protein powder can vary wildly in texture and sweetness, so taste your mixture before sealing the jar and adjust honey or vanilla if needed.
03 -
  • Use a jar with a wide mouth so you can stir easily and scrape out every creamy spoonful without frustration.
  • If your protein powder tends to clump, whisk it into the milk and yogurt mixture separately before adding it to the oats.
  • A pinch of flaky sea salt on top right before eating brings out the peanut butter flavor in a way that feels almost indulgent.
