# Expert Advice:

01 -
  • It packs over 40 grams of protein, so you stay full through meetings, workouts, or whatever chaos the morning throws at you.
  • Zero cooking required, just stir, chill, and wake up to breakfast that tastes like dessert but fuels like a power bar.
  • Endlessly customizable with whatever fruit, nut butter, or toppings you have lying around, so you never get bored.
02 -
  • Stir the oats thoroughly the night before, or you'll wake up to a layer of dry oats floating on top and a puddle of peanut sludge at the bottom.
  • Not all protein powders play nice with overnight oats; some turn gummy or gritty, so test a new brand in a small batch first.
  • If your oats are too thick in the morning, don't panic, just stir in milk a tablespoon at a time until it feels right.
03 -
  • Whisk the peanut butter mixture in a separate bowl first, trying to stir thick peanut butter directly into dry oats is a recipe for clumps and frustration.
  • Add a tiny pinch of flaky sea salt on top right before eating, it makes the peanut butter taste richer and the whole thing feel a little fancy.
  • If you're using a new protein powder, test it in a small jar first, some brands turn overnight oats into a science experiment gone wrong.
