# Expert Advice:

01 -
  • You prep it once at night and grab it cold in the morning, no cooking required.
  • The protein keeps you full for hours without that mid-morning crash.
  • It tastes like peanut butter cookie dough but actually fuels your day.
  • You can customize it endlessly with different nut butters, fruits, and toppings.
02 -
  • Stir the oats really well before refrigerating, or you'll end up with dry oat patches and a puddle of liquid at the bottom.
  • If your protein powder is gritty or clumpy, whisk it into the milk mixture first instead of adding it dry.
  • Don't skip the pinch of salt, it makes the peanut butter flavor pop and balances the sweetness.
  • Add delicate fruit like berries just before eating, otherwise they'll bleed color and get mushy overnight.
03 -
  • Make two or three jars at once on Sunday night and you've got grab-and-go breakfasts all week.
  • Use a wide-mouth jar so you can stir easily and get every last bit out with a spoon.
  • If you're not a fan of cold oats, microwave them for 30 to 60 seconds and they'll be warm and cozy.
  • A pinch of flaky sea salt on top right before eating makes the peanut butter taste even richer.
