In a medium mixing bowl, whisk together the Greek yogurt, almond milk, cooled coffee (or cold brew), maple syrup, and vanilla extract until smooth and well-mixed.
Stir in rolled oats, protein powder, chia seeds, and cacao powder until completely combined.
Fold in 1 tablespoon mini chocolate chips, so they are dispersed throughout the batter.
Cover the bowl with plastic wrap and refrigerate for no less than 4 hours and up to overnight, allowing the oats to soak up the liquids and soften.
To serve, spoon the mixture into two 12-ounce mason jars or bowls. Top with a dollop of more yogurt, a sprinkle of the rest of the mini chocolate chips, and a drizzle of almond butter for more protein.
