# How-To Steps:

01 - Select a clean jar or container with a tight-fitting lid and 12 to 14 fluid ounce capacity.
02 - Add rolled oats to the jar. 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 1 to 2 tablespoons 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 to eliminate dry pockets.
05 - If the mixture is very thick, add a splash more milk and stir again.
06 - Stir in sturdy fruits or chocolate chips if using. Reserve delicate fruit for just before serving.
07 - Seal the container and refrigerate for at least 4 hours, preferably 8 to 12 hours.
08 - In the morning, stir well and check consistency. Add more milk if desired.
09 - Top with 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. Refrigerate leftovers for up to 2 days and add fresh fruit just before serving.

# Expert Advice:

01 -
  • You prep it once and wake up to breakfast that's already done, no blender or stove required.
  • The protein keeps you genuinely full for hours, not just until your commute ends.
  • It tastes like dessert but fuels you like a real meal, which feels like cheating the system.
  • You can eat it cold, straight from the jar, in your car or at your desk without any guilt.
02 -
  • If you skip stirring well at the start, you'll hit dry clumps of protein powder at the bottom in the morning, and it's deeply disappointing.
  • The oats thicken a lot overnight, so what looks too liquidy at night will be perfect by morning.
  • If you add fresh banana the night before, it turns brown and slimy, so slice it fresh in the morning instead.
03 -
  • Make three jars on Sunday night and you've got breakfast sorted through Wednesday without thinking about it.
  • If you're taking it to go, pack toppings separately in a small container so they stay fresh and crunchy.
  • Use a wide-mouth jar so you can actually stir and eat from it without frustration.
  • If your oats are too thick in the morning, add milk one tablespoon at a time until it's just right.
