# How-To Steps:

01 - Select a clean jar or container with a tight-fitting lid with 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, ensuring there are no 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 now, if using. Reserve delicate fruit for addition just before serving.
07 - Seal the container and refrigerate for at least 4 hours, preferably overnight for 8 to 12 hours.
08 - In the morning, stir well and check the consistency. Add a bit more milk if desired.
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 Hints:

01 -
  • You make it once at night and breakfast is done before you even wake up.
  • The peanut butter and protein powder turn plain oats into something rich and filling that actually tastes like a treat.
  • You can eat it straight from the jar, no dishes, no cleanup, no excuses.
02 -
  • If you add the protein powder directly to the liquid without whisking it first, you'll end up with chalky lumps that never dissolve.
  • The oats will absorb way more liquid than you think overnight, so if it looks a little soupy when you first mix it, that's actually perfect.
03 -
  • Use a jar with a wide mouth so you can actually stir the oats all the way to the bottom without making a mess.
  • Add a tiny pinch of flaky sea salt on top right before eating, it makes the peanut butter flavor pop in a way that regular salt just doesn't.
