# How To Make It:

01 - Select a clean jar or container with a tight-fitting lid having 12 to 14 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. Reserve delicate fruit for 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 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.

# Expert Advice:

01 -
  • It waits for you in the fridge, ready to grab when you have no time to think.
  • The texture is thick and satisfying, like dessert pretending to be breakfast.
  • You can customize it endlessly and never get bored of the same jar twice.
  • High protein keeps you full through meetings, errands, or whatever the morning throws at you.
02 -
  • Stir the oats extremely well before refrigerating or you'll hit a dry, chalky layer at the bottom in the morning.
  • Protein powder can make the oats thicken a lot, so add extra liquid if it looks pasty after mixing.
  • Don't skip the pinch of salt; it makes the peanut butter taste richer and more intentional.
  • If using natural peanut butter, stir the jar first so the oil is evenly distributed, or it won't blend smoothly.
03 -
  • Use a jar with measurement marks on the side so you can eyeball the ratios without dirtying a measuring cup.
  • If you hate cold oats, microwave the jar (without the metal lid) for 45 seconds and stir; it turns into warm, cozy porridge.
  • Double the peanut butter and skip the protein powder for a simpler, richer version that still keeps you full.
  • Add a tablespoon of instant coffee or espresso powder to the mix for a mocha peanut butter version that tastes like dessert.
