Mix the oats: In a jar or container, stir together rolled oats, cocoa powder, chia seeds, maple syrup, espresso shots (or filtered coffee), and plant-based milk. Mix well.
Chill: Cover and refrigerate overnight (or at least 4 hours) until the oats and chia seeds absorb the liquid and thicken.
Make the cream layer: In a small bowl, mix coconut yoghurt with maple syrup and vanilla until smooth.
Assemble: In a jar or glass, layer your coffee oats and coconut cream. Repeat layers.
Dust with cocoa powder just before serving.
