# How-To:

01 - Select a clean jar or container with a tight-fitting lid, preferably 12 to 14 ounces in capacity.
02 - Add rolled oats to the jar and stir in chia seeds, flaxseed, cinnamon, and protein powder if using. Add a pinch of salt.
03 - In a separate bowl, whisk together milk, Greek yogurt, peanut butter, vanilla extract, and honey or maple syrup until smooth. Add water or extra milk if the mixture is too thick.
04 - Pour the peanut butter mixture over the oats and dry ingredients. Stir very thoroughly, ensuring no dry pockets remain.
05 - If the mixture is very thick, add a splash more milk and stir again until desired consistency is achieved.
06 - Stir in sturdy fruits or chocolate chips if using. Reserve delicate fruits for just before serving.
07 - Seal the container and refrigerate for at least 4 hours, preferably overnight for 8 to 12 hours, allowing flavors to meld and oats to fully hydrate.
08 - In the morning, stir well and check consistency. Add additional milk if desired for looser texture.
09 - Top with a spoonful of peanut butter, fresh fruit, yogurt, nuts or seeds, and a drizzle of honey or maple syrup. Sprinkle with flaky sea salt if desired.
10 - Enjoy straight from the jar or transfer to a bowl. Refrigerated leftovers keep for up to 2 days; add fresh fruit just before serving.

# Expert Advice:

01 -
  • It delivers serious protein without any powdery aftertaste or chalky texture.
  • You can make it in under ten minutes before bed and wake up to breakfast already done.
  • The peanut butter makes it taste like a treat, not a health kick.
  • It keeps you full for hours without that mid-morning energy crash.
02 -
  • Stir the mixture really well before refrigerating or you'll end up with a dry oat puck at the bottom and a pool of liquid on top.
  • If your protein powder clumps, whisk it into the milk mixture first before adding the peanut butter.
  • Don't skip the pinch of salt, it makes the peanut butter taste twice as good.
  • Let it sit overnight if you can, four hours works but eight is when the magic happens.
03 -
  • Make three jars at once on Sunday night and you've got breakfast sorted for half the week.
  • If the peanut butter is hard to mix in, warm it slightly in the microwave first so it blends smooth.
  • Always taste the mixture before refrigerating, it's easier to adjust sweetness or add a pinch of salt now than in the morning.
  • Use a jar with a wide mouth so you can stir easily and eat straight from it without making a mess.
