In a high speed blender, add cottage cheese, milk, espresso, maple syrup and vanilla extract.
Process until smooth, about 30 seconds. Add chia seeds, pulse and let stand for 5 minutes. Pulse once more and pour into a glass dish, making sure to scrape down chia seeds from the walls of a blender.
Cover and refrigerate for at least 6 hours or best overnight.
Spread Greek yogurt on top and dust with cacao powder, using a small mesh sieve. Enjoy cold!
