In a food processor or blender, blitz the rolled oats until they turn into a fine powder. Add the remaining ingredients except the cacao powder, and blend well until totally combined.
Let this sit for 5 minutes, then blend again to ensure the chia seeds have thoroughly dispersed.
Divide this mix between a few individual small glasses or dishes you’d like to serve out of. Let them chill in the fridge for 45 minutes, or up to overnight.
When ready to serve, use a fine sieve to dust the top of each dish with the cacao powder, and enjoy!
