In a bowl, mix together the oats, milk, espresso powder, cocoa powder, maple syrup, and vanilla extract until well combined.
Transfer the mixture into an airtight container and let it soak and thicken in the fridge overnight or for at least 3 to 4 hours if you can't wait that long.
The next morning, layer the oats with vanilla yogurt and dust the top with cocoa powder.
Enjoy your delicious and satisfying Tiramisu Overnight Oats!
Notes
Adjust the amount of maple syrup according to your desired level of sweetness.
Opt for old-fashioned rolled oats for the best texture and soaking ability. They work wonders in overnight oats!
