01 - In a medium bowl or jar, combine oats, milk, Greek yogurt, chia seeds, maple syrup, vanilla extract, cinnamon, and salt. Stir well until fully incorporated and smooth.
02 - Add almond butter to the oat mixture and mix thoroughly until completely blended throughout the base.
03 - Gently fold in mini chocolate chips and chopped walnuts or pecans if using, distributing evenly.
04 - Cover the bowl or jar securely with a lid. Refrigerate for at least 6 hours, preferably overnight, to allow oats to soften and flavors to meld.
05 - In the morning, give the oats a thorough stir. Add an extra splash of milk if the consistency is too thick for your preference.
06 - Serve chilled. Top with additional chocolate chips or a drizzle of nut butter if desired.
