I've wanted to make these cupcake for years, since I first saw them in the very fun Hello, Cupcake book and I figured April Fool's Day was the perfect excuse, especially since we had special guests for dinner. I tinted my buttercream frosting with a few drops of yellow food coloring to get the perfect spaghetti noodle color, then spread the cupcakes with a thin layer to cover then top of the cake. Next I piped it through a small round tip to get the noodles. It doesn't take any special technique--you just squeeze the icing and the frosting 'noodles' itself!
The Ferrero Rocher meatballs really made it, though--with the strawberry jam coating, they looked eerily realistic! I even used some red and white checked cupcake liners from my stash to echo a red and white checked tablecloth like you might see at an Italian restaurant.
They were really fun to make and delicious to eat, both a good trick and a good treat!
