Add rolled oats, chia seeds, maple syrup, oat milk, espresso, and a pinch of salt to a mixing bowl.

Stir until fully combined, then check the consistency and add a splash more oat milk if the mixture seems too thick.

Transfer the mixture to an airtight container or jar, cover, and refrigerate for at least 2 hours or overnight until the oats are fully hydrated and creamy.

In a small bowl, mix the protein yogurt and Manuka honey until smooth.

Spoon the yogurt–honey mixture over the chilled oats and spread into an even layer.

Dust generously with cacao powder to finish.

Serve directly from the jar or transfer to a bowl and garnish with an additional drizzle of Manuka honey if desired.
