Whisk PB2 and whey protein into almond milk until smooth. Add oats, 1/2 tbsp (6 grams) chia seeds, and melted peanut butter and stir until combined. Refrigerate in a covered container overnight.
Place blueberries in a microwave safe dish. Microwave for 1 to 1 1/2 minutes or until blueberries can be easily mashed with the back of a spoon.
Mash the blueberries until that are all burst. Add remaining chia seeds and stir. Refrigerate overnight or at least 1 hour.
Top overnight oats with blueberry chia jam before serving.
Notes
Frozen blueberries work best for the blueberry chia jam.
If the oats are too runny for your liking after setting up overnight, heat them in the microwave for 1 minute OR add a couple more tablespoons of oats to thicken them up.
