You take a slightly taller glass per serving and fill it with 3 tablespoons of yoghurt, then add a layer of crumbled amarettini, followed by 3 tablespoons of apple sauce. Then do the same thing again. Finally, a layer of yogurt on top.
Use a sharp knife to scrape the chocolate off the rasp (this creates such small rolls). Decorate the dessert with the chocolate flakes and one cookie each.
The ingredients are enough for about 3 glasses, applesauce remains a little. If you want, you can sweeten the yogurt with a little sugar.
