# Directions:

01 - Select a clean jar or container with a tight-fitting lid, 12 to 14 fluid ounces in 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 no dry pockets remain.
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. Reserve delicate fruits to add just before serving.
07 - Seal the container and refrigerate for at least 4 hours, preferably overnight for 8 to 12 hours.
08 - In the morning, stir well and check consistency. Add more milk if desired to reach preferred texture.
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; add fresh fruit just before serving.

# Expert Suggestions:

01 -
  • It tastes like dessert but fuels you like a real meal, with enough protein to keep you full until lunch.
  • You can eat it straight from the jar, no reheating, no fuss, no dishes piling up before your coffee kicks in.
  • Every spoonful is creamy and rich, with that nostalgic peanut butter flavor that makes breakfast feel like a treat.
  • It adapts to whatever you have on hand, swapping milks, nut butters, or toppings without losing its magic.
02 -
  • If you skip stirring thoroughly, you'll hit a pocket of dry protein powder at the bottom and it will ruin your morning, trust me.
  • The texture gets thicker as it sits, so if you like it looser, add extra milk in the morning instead of trying to fix it the night before.
  • Delicate fruit like raspberries or sliced strawberries should go on top in the morning, not stirred in overnight, or they'll turn to mush.
  • If your protein powder is unflavored, add a little extra vanilla or sweetener, otherwise the oats can taste flat and chalky.
03 -
  • Make three or four jars at once on Sunday night so you don't have to think about breakfast until Thursday.
  • If you're taking it to work, pack the toppings separately in a small container so they stay fresh and crunchy.
  • Use a jar with measurement marks on the side so you can eyeball the ingredients without dirtying a measuring cup.
  • If your protein powder tends to clump, sift it through a fine mesh strainer before adding it to the jar.
