Dessert dirt cups can be made with all sorts of pudding flavors. I use vanilla because I love the distinction between the black and white layers, however, truth be told, using a chocolate pudding layer is the most popular choice. For fun, you could color a vanilla pudding layer using gel food coloring and make it whatever color you want.  A fun way to switch things up even more would be to use a different flavor of Oreo! Golden Oreos, mint Oreos (hello St. Patrick's Day), or birthday cake Oreos would be great.
