Mint Chip Freeze

Yummy! My sister made this for me when I went to visit. It's something that would easily feed a large group of friends.

Ingredients:
~ 1 pack regular oreos, crushed
~ 1/4 c. melted butter
~ 1/2 can- 6 oz evaporated milk
~ 1/2 c. sugar
~ 1/4 c. butter, cubed
~ 1 square baking chocolate
~ 1/2 gallon mint chocolate chip ice cream, softened
~ 1/2 carton- 8 oz. cool whip
~ shaved chocolate Hershey's bar, shaved with a potato peeler)

Directions:
In a large bowl combine cookies and butter. Press into the bottom of a 13x9 pan and refrigerate for 30 minutes. In a small saucepan combine milk, sugar, butter and chocolate. Cook over medium heat until thick and bubbly (about 12 minutes). Remove from heat and cool completely. Spread softened ice cream over crust. Pour chocolate sauce over top of ice cream and evenly spread. Freeze until firm. Spread cool whip on top and top with chocolate shavings. Remove from freezer about 10 minutes before serving.
