Pistachio Ice Cream Torte

This is a recipe from my fiance's grandmother and holy smokes is it good. The pistachio flavor isn't super strong, but that might be because it has so much other deliciousness going on. This made a lot, so you might want to cut the recipe in half if you're just making it for two people.

Ingredients:
-1 bag Oreo cookies, crush half into fine pieces, crush other half into bigger pieces
-1/2 stick of butter, melted
-1 quart vanilla ice cream (1/2 of a 1/2 gallon), softened
-1 8oz tub of Cool Whip, softened in fridge
-1 pistachio flavored Jello pudding mix
-2 cups milk

Steps:
1. Let Cool Whip soften in fridge for a couple of hours. Let ice cream soften for about 15 minutes on counter (you can pull it out as you're making everything else).
2. Crush half the bag of Oreos very finely and mix with melted butter. Crush the other half of the bag into bigger pieces and set aside.
3. Push the finely crushed Oreos into the bottom of a 13X9 pan with your fingers to form a crust.
4.Make pudding as directed.
5. Mix pudding with ice cream and spread over cookie crust.
6. Spread Cool Whip over pudding/ice cream mixture.
7. Top with the remaining crushed up Oreos.
8. Let re-freeze before serving.
Note: When you serve, it is best to let the pieces sit out for about 10 minutes to re-soften and get a nice smooth, pudding-like consistency.
