# How to Make It:

01 - Select a clean jar or container with a tight-fitting lid with 12 to 14 fluid ounce capacity.
02 - Add rolled oats to the jar. Stir in chia seeds, flaxseed, cinnamon, and protein powder if using. Add a pinch of salt.
03 - In a separate bowl, whisk together milk, Greek yogurt, peanut butter, vanilla extract, and honey or maple syrup until smooth. Add 1 to 2 tablespoons water or extra milk if the mixture is too thick.
04 - Pour the peanut butter mixture over the oats and dry ingredients. Stir very thoroughly, ensuring there are no dry pockets.
05 - If the mixture is very thick, add a splash more milk and stir again.
06 - Stir in sturdy fruits or chocolate chips now if using. Add delicate fruit just before serving.
07 - Seal the container and refrigerate for at least 4 hours, preferably 8 to 12 hours.
08 - In the morning, stir well and check the consistency. Add a bit more milk if desired.
09 - Top with a spoonful of peanut butter, fresh fruit, yogurt, nuts or seeds, and a drizzle of honey or maple syrup. Sprinkle with flaky sea salt if desired.
10 - Enjoy straight from the jar or transfer to a bowl. Refrigerated leftovers keep for up to 2 days with fresh fruit added just before serving.

# Expert Advice:

01 -
  • It takes ten minutes at night and gives you a breakfast that feels indulgent but keeps you full until lunch.
  • The peanut butter melts into the oats overnight, creating this velvety texture that tastes like dessert but delivers serious protein.
  • You can make it in a jar, eat it in a jar, and clean up one jar—no morning mess, no decisions, no stress.
02 -
  • If you don't stir the peanut butter mixture thoroughly into the oats, you'll end up with clumps of protein powder and dry oats at the bottom—learned that the hard way on day one.
  • Let the oats sit for at least four hours, but eight to twelve is ideal; the texture changes completely and the flavors meld into something much better than what you started with.
03 -
  • Whisk the peanut butter mixture in a separate bowl first—it blends way more smoothly than trying to stir it directly into the oats.
  • A pinch of flaky sea salt on top right before eating makes the whole jar taste more balanced and less one-note sweet.
