As with a tiramisu, it all comes down to how great your coffee is. For this recipe, try to use the best espresso you can get hold of. If you don’t have an espresso machine, brew some strong coffee with a coffee percolator or cafetiere.
The real magic happens when you dust the top of the oats with cocoa and chocolate. Save this step until the next day, when you’re ready to serve.
For the yogurt layer, it’s fine to use sweetened, vanilla flavored yogurt if you have a sweet tooth. If not, an unsweetened yogurt will work great too, but be sure to whisk in the maple syrup beforehand.
