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 now if using. Reserve delicate fruit to add just before serving.
07 - Seal the container and refrigerate for at least 4 hours, preferably 8-12 hours overnight.
08 - In the morning, stir well and check the consistency. Add a bit more milk if desired.

# Expert Advice:

01 -
  • You mix it once at night and wake up to breakfast thats already waiting, no blender or stovetop needed.
  • The protein powder and Greek yogurt keep you full for hours, unlike sugary granola or toast that leaves you hungry by ten.
  • Every jar tastes like peanut butter cookie dough but fuels your whole morning without the sugar crash.
  • You can double or triple the batch and have grab and go breakfasts all week long.
02 -
  • Protein powder can turn the oats chalky if you dont whisk it really well with the wet ingredients first, so take your time.
  • If you skip the Greek yogurt the oats will be thinner and less tangy, so add an extra tablespoon of chia seeds to thicken it back up.
  • Oats keep soaking up liquid overnight, so what looks perfect at bedtime might be thick by morning, just stir in a splash of milk and it softens right up.
03 -
  • Always whisk the peanut butter and yogurt together first before adding them to the oats, or you will end up with peanut butter globs that never mix in.
  • Use a jar thats bigger than you think you need, oats expand overnight and a too small jar makes stirring impossible without a mess.
  • Add a tiny pinch of flaky sea salt on top right before you eat, it makes the peanut butter taste twice as good and balances any sweetness.
