# Directions:

01 - Select a clean jar or container with a tight-fitting lid with 12 to 14 ounce capacity.
02 - Add rolled oats to the jar and 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 until desired consistency is achieved.
06 - Stir in sturdy fruits or chocolate chips now if using. Reserve delicate fruit for 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 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 tips:

01 -
  • You prep it once and wake up to breakfast thats already waiting, no mixing bowls or morning decisions required.
  • The peanut butter and protein powder turn simple oats into something that actually keeps you full until lunch.
  • Its endlessly customizable: swap the nut butter, change the fruit, adjust the sweetness, and it still works every time.
02 -
  • If you skip the thorough stirring in step four, youll end up with dry oats on the bottom and a puddle of peanut milk on top.
  • Protein powder can make the mixture very thick; always add a little extra liquid and check again in the morning.
  • Dont add delicate fruit like banana slices or raspberries the night before unless you want them mushy and brown.
03 -
  • Use a jar thats wider at the top so you can stir and scoop easily without fishing around with a spoon.
  • Let the peanut butter come to room temperature before mixing; it blends smoother and doesnt clump in cold milk.
  • If the oats taste bland, you need more salt; a pinch makes all the flavors come forward.
  • For meal prep, make the base in a big batch and divide it into jars, then customize toppings daily so it never feels repetitive.
