For crust: Mix all ingredients together well and press into the bottom of a glass 9x13" pan. Bake at 375 for about 12-15 minutes or till very lightly browned. Let cool completely.
Layer 1: Whip the 1 cup of cream till it holds soft peaks. Add sugar and vanilla to taste. (I don't like it really sweet.) Set it aside.
Beat the cream cheese and powdered sugar till smooth and creamy. Fold in only about half of the whipped cream. Spread on top of cooled crust. Cover the bowl of remaining whipped cream and place it in the refrigerator.
Layer 2: Beat the pudding and milk for about 1 minute. Quickly pour over the cream cheese layer. Cover with plastic wrap and chill till pudding is set, about 1 hour.
Layer 3: Carefully spread the remaining whipped cream over the pudding layer. Top with chocolate curls if desired.
