# How-To Steps:

01 - Select a clean jar or container with a tight-fitting lid with a capacity of 12 to 14 fluid ounces.

04 - Pour the peanut butter mixture over the oats and dry ingredients. Stir very thoroughly, ensuring there are no dry pockets.

07 - Seal the container and refrigerate for at least 4 hours, preferably overnight for 8 to 12 hours.

# Expert Advice:

01 -
  • It gives you a breakfast that feels indulgent but delivers serious protein to keep you full until lunch.
  • Everything happens while you sleep, so mornings become effortless even on your busiest days.
  • The peanut butter blends into the oats so smoothly it tastes like dessert you're allowed to eat at sunrise.
  • You can prep a few jars at once and have grab-and-go breakfasts waiting all week long.
02 -
  • Stir the mixture thoroughly after combining wet and dry ingredients or you will end up with a clump of protein powder at the bottom.
  • If you skip the pinch of salt, the oats will taste flat and the peanut butter flavor won't shine through.
  • Let the oats soak for at least 8 hours if you can, anything less and the texture stays a bit chalky instead of creamy.
03 -
  • Use natural peanut butter that has a layer of oil on top, it blends into the oats more smoothly than the no-stir kind.
  • If your protein powder tends to clump, whisk it with the milk first before adding the yogurt and peanut butter.
  • A pinch of flaky sea salt on top right before eating makes the whole jar taste more complex and craveable.
  • Let the jar sit on the counter for 5 minutes before eating if you don't like it cold, it takes the chill off without needing a microwave.
