20 - Pinch of flaky sea salt

# Steps:

01 - Select a clean jar or container with a tight-fitting lid and 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 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 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 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.

# Tips from the Pros:

01 -
  • It feels indulgent but fuels you for hours without the mid-morning crash.
  • You can prep it in under ten minutes and wake up to breakfast that's already better than anything you'd buy.
  • The peanut butter blends into the oats so smoothly that every bite tastes rich and intentional, not like health food.
02 -
  • Whisk the peanut butter and yogurt together in a separate bowl first, or you'll end up with stubborn clumps floating in your oats.
  • If you skip the extra splash of milk or water when the mixture looks thick, you'll wake up to oats that are more paste than porridge.
  • Chia seeds are optional, but if you use them, expect the oats to thicken significantly, so hold back a little on the initial milk.
03 -
  • Use a jar with a wide mouth so you can stir easily and get your spoon all the way to the bottom without scraping your knuckles.
  • If your protein powder tends to clump, sift it into the oats or whisk it into the milk first before adding the peanut butter.
  • A pinch of flaky sea salt on top right before eating makes the peanut butter flavor pop and turns a simple breakfast into something memorable.
