Using a large ice cream scoop, scoop a heaping ball of dolce de leche. Before releasing the ice cream from the ice cream scoop, shove 1 mini peanut butter cup into the center of the ice cream ball. With a spoon push the ice cream over to cover the peanut butter cup. Repeat 3 more times. Roll the stuffed ice cream balls in the crushed up cookie crumbs and then transfer to the freezer for 15 to 20 minutes to firm up a bit. To serve, place an ice cream ball in a dessert bowl and pour both chocolate and caramel sauce over the top.
