# Expert Suggestions:

01 -
  • It actually keeps you full, no mid-morning snack panic required.
  • You can eat it straight from the jar, which means one less dish to wash.
  • The peanut butter and protein powder turn plain oats into something that tastes like dessert but fuels your whole morning.
02 -
  • If you don't stir the peanut butter mixture well before adding it to the oats, you'll end up with a clump of peanut butter at the bottom, which is disappointing when you're half awake.
  • Protein powder can make the oats thick and chalky if you don't add enough liquid, so always check the consistency before sealing the jar.
  • Delicate fruits like banana and strawberries will turn brown and mushy overnight, so save them for the morning and your oats will look and taste fresher.
03 -
  • Use a jar with a wide mouth so you can stir and eat without fighting the opening, it makes a bigger difference than you'd think.
  • If your protein powder has a strong flavor, start with half a scoop and work your way up, some brands can overpower the peanut butter if you're not careful.
  • A pinch of flaky sea salt on top right before eating makes the peanut butter taste twice as good and adds a little crunch that plain oats don't have.
