Using two spoons, create little "piles" of Nutella spread on a plate or a tray and freeze for 2 hours.
Mix the cream cheese and powdered sugar in a bowl until well combined. Pour in the coffee and mix well until you get a smooth light brown cream. Add the crumbs, mix until you reach a flexible dough-like texture and refrigerate for at least 2 hours.
When the dough is thoroughly cold, remove it from the fridge. Oil your hands and spread a small amount of it on the palm of your hands. Put the frozen Nutella pieces on top, close gently and roll into a ball.
Place the chocolate balls on a tray lined up with parchment paper and refrigerate for 30 minutes.
Remove from the fridge, coat the balls with ground nuts, coconut flakes, cocoa powder, sprinkles or anything else you like and enjoy! Store in the fridge/freezer.
