01 - In a medium bowl or mason jar, add oats, milk, Greek yogurt, cocoa powder, chia seeds, maple syrup or honey, peanut butter, and vanilla extract.
02 - Stir all ingredients until completely combined and peanut butter is evenly distributed throughout the mixture.
03 - Cover the container and refrigerate for at least 6-8 hours, preferably overnight, allowing oats and chia seeds to absorb liquid and thicken.
04 - Before serving, stir the oats again. If mixture is too thick, add a small splash of milk to achieve desired texture.
05 - Top with mini chocolate chips, chopped roasted peanuts, and fresh sliced fruit. Serve cold.
