# How To Make:

01 - Select a clean jar or container with a tight-fitting lid, preferably 12 to 14 fluid ounces in 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 and mix well.
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 of 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 throughout.
05 - If the mixture is very thick, add a splash more milk and stir again until well combined.
06 - Stir in sturdy fruits or chocolate chips now if using. Reserve delicate fruit to add just before serving.
07 - Seal the container and refrigerate for at least 4 hours, preferably 8 to 12 hours, allowing the oats to fully absorb the liquid.
08 - In the morning, stir well and check the texture. Add additional milk if a looser consistency is 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 gives you 40 grams of protein without turning on a single burner or blending a thing.
  • The texture is silky and thick, more like peanut butter mousse than plain oatmeal.
  • You can make it Sunday night and eat it Tuesday morning, it only gets better.
  • It tastes indulgent enough to feel like a treat but keeps you satisfied for hours.
02 -
  • Whisk the peanut butter mixture in a separate bowl first, or you'll chase clumps of protein powder around the jar forever.
  • The oats will thicken as they sit, so start with a slightly loose consistency and adjust in the morning.
  • If your protein powder is gritty or chalky, blend the wet ingredients in a shaker bottle before pouring.
  • Always stir from the bottom before eating, the oats settle and the top looks deceptively thick.
03 -
  • Use a whisk or a shaker bottle to blend the wet ingredients first, it prevents protein powder clumps and makes the mixture silky.
  • Let the oats sit overnight, not just four hours, the texture transforms and the flavors deepen.
  • Always taste before adding sweetener, ripe fruit and vanilla protein powder often provide enough sweetness on their own.
  • A pinch of flaky sea salt on top before eating brightens every flavor and makes the peanut butter taste richer.
