Mix powdered sugar, whipped topping and cream cheese in a bowl. Add more or less cream cheese, sugar or whipped topping to desired consistency. Set aside in the refrigerator for 10 minutes. In a separate bowl, prepare instant pudding according to directions and place in refrigerator for 5 minutes.
Next, slice the Ding Dongs in half and lay them cream-side-up on a plate or serving dish lined with wax paper. Layer pudding in the middle of ½ Ding Dong and spread out to the edge of the snack cake. Add a layer of chocolate chips and a final layer of cream cheese, whipped topping and powdered sugar mixture. Place the other ½ Ding Dong on top of the layers and voila.a Ding Dong sandwich. Add a final layer of cream cheese, whipped topping and powdered sugar mixture with chocolate chips on top of the treat. Repeat.
