04 - Pour the peanut butter mixture over the oats and dry ingredients. Stir very thoroughly, ensuring there are no dry pockets.

07 - Seal the container and refrigerate for at least 4 hours, preferably overnight for 8-12 hours.

# Expert Tips:

01 -
  • You wake up to breakfast that's already ready, no cooking or waiting required.
  • Each spoonful delivers serious staying power thanks to protein, healthy fats, and whole grains working together.
  • The peanut butter melts into the oats overnight, creating a velvety, almost dessert-like texture.
  • You can prep a few jars at once and have grab-and-go breakfasts lined up for days.
02 -
  • I once added the protein powder without whisking it into the wet ingredients first and ended up with chalky clumps I had to fish out, always mix it with the oats or blend it with the liquids.
  • Using too little liquid makes the oats absorb everything and turn into a dense brick, so err on the side of a bit more milk and adjust in the morning.
  • If your peanut butter is the natural kind with oil on top, stir the jar well before measuring or your oats will be dry and the texture will be off.
03 -
  • Use a jar with a wide mouth so you can stir easily and scrape every last bite without a struggle.
  • If you're not a fan of cold oats, microwave them for 60 to 90 seconds and they turn into warm, cozy peanut butter porridge.
  • Keep a stash of single-serve protein powder packets in your pantry so you can make a jar anytime without measuring.
