# Expert Suggestions:

01 -
  • It tastes like peanut butter cookie dough but keeps you satisfied for hours without a sugar crash.
  • You can prep it in under ten minutes the night before and wake up to breakfast already done.
  • The texture is thick and creamy, not watery or sad like some overnight oats can be.
  • It packs serious protein without needing a blender or any cooking at all.
02 -
  • Whisk the peanut butter mixture separately first or you will end up with sticky clumps stuck to the oats that never dissolve.
  • Don't skip the pinch of salt because it makes the peanut butter flavor bloom and keeps everything from tasting one-note sweet.
  • If you add too much milk at the start, the oats will be soupy, so start with the recipe amount and adjust in the morning.
03 -
  • Use natural peanut butter that you have to stir because it blends smoother and tastes less sweet than the no-stir kind.
  • If your protein powder is unflavored, add an extra splash of vanilla or a pinch of cinnamon so the oats don't taste flat.
  • Warm them gently in the microwave for 30 seconds if you want a cozy breakfast on a cold morning.
