Place the Vanilla Wafers in the Food Processor or Blender, and pulse until you have crumbs.
You'll need about 3/4 (or possibly more) of a box of Vanilla wafer to equal 2 cups.
Add the sugar, and stir well.
Melt the butter in the microwave, and add to the crumbs/sugar, and stir well to mix, and coat crumbs.
Line the bottom of a Spring-form pan with Parchment paper, and pour the crumbs into the pan
Press the crumbs evenly in the pan.
Unwrap 5 of the Twinkies, and cut them in half.
Stand the Twinkies around the edge of the Spring-form pan with the rounded side facing the outside of the pan.
Place the pan in the freezer. (If you don't have enough Twinkie halves to go around the edge of the pan, cut another one or two Twinkies in half until the edge of the pan has been filled).
