# Expert Advice:

01 -
  • It delivers serious staying power without any morning effort, just grab and go.
  • The peanut butter and protein powder turn ordinary oats into something that tastes indulgent but keeps you steady for hours.
  • You can customize it endlessly, swapping nut butters, milks, and toppings to match your mood or whatever's in the pantry.
02 -
  • Stir the oats really well before refrigerating, I once skipped this and found a dry clump of protein powder at the bottom the next morning.
  • If your protein powder is chalky or clumpy, whisk it into the milk mixture separately before adding the peanut butter to avoid gritty bits.
  • Don't skip the pinch of salt, it's the difference between tasty and truly crave-worthy.
03 -
  • Warm your peanut butter for a few seconds in the microwave before whisking it in, it blends way smoother and you won't end up with stubborn clumps.
  • Use a fork to stir instead of a spoon when you first combine everything, the tines help break up any pockets of protein powder or yogurt faster.
  • If your oats are too sweet in the morning, stir in an extra spoonful of plain yogurt to balance it out on the fly.
