Add all ingredients to a small jar or other container. Stir until everything is evenly combined (you'll need a couple extra stirs than regular overnight oats to make sure the peanut butter is all mixed up!)
1/2 cup milk, 1/4 cup Greek yogurt, 1 tablespoon creamy peanut butter, 1/4 cup old-fashioned oats, 1 tablespoon ground flax seeds, 1 tablespoon chia seeds, 1 scoop protein powder
Cover the jar and place in the fridge overnight, or at least 4 hours until set.
Before serving, give the oats a final stir. Depending on the protein powder you used and how thick you prefer your overnight oats, you may need to add an extra tablespoon or two of milk. Adjust as needed, stir, garnish as desired, and enjoy!
