# Directions:

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

03 - In a separate bowl, whisk together milk, Greek yogurt, peanut butter, vanilla extract, and honey or maple syrup until smooth. Add 1-2 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 if using. Reserve delicate fruit to add just before serving.
07 - Seal the container and refrigerate for at least 4 hours, preferably overnight for 8-12 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; add fresh fruit just before serving.

# Expert Tips:

01 -
  • It takes less time to assemble than brewing coffee, and you wake up to breakfast thats already waiting.
  • The protein keeps you full for hours without that mid-morning crash or desperate snack hunt.
  • You can swap the peanut butter or milk for whatever you have, and it still works perfectly.
  • Its genuinely delicious, not just healthy, with a creamy richness that feels like dessert for breakfast.
02 -
  • If you dump the protein powder in last, it will clump and turn gritty no matter how much you stir, so always mix it with the dry oats first.
  • Natural peanut butter needs to be whisked into the milk mixture or it will float in greasy blobs instead of blending smoothly.
  • The oats will keep thickening in the fridge, so what looks too loose at night will be perfect by morning.
03 -
  • Use a jar that's wider at the top so you can actually stir and scrape the bottom without making a mess.
  • If your protein powder has a strong artificial taste, use unflavored and let the peanut butter and vanilla do the flavoring instead.
  • A pinch of flaky sea salt on top right before eating makes the peanut butter taste richer and the sweetness more balanced.
