These peanut butter overnight oats are made with old-fashioned oats, peanut butter, chia seeds, and milk. Prep time is just 60 seconds the night before, so you'll save time during your busy morning and you can enjoy your oatmeal on-the-go!
Add old-fashioned oats and chia seeds to a 1/2 pint mason jar or other container with a lid.
Add peanut butter, honey if using, and milk, and stir to combine. Place jar in refrigerator for at least 4 hours (or overnight) to allow chia seeds to soften.
Add an extra splash of milk right before enjoying, if needed. Top with berries or banana slices if desired.
