1. Pulse cookies in a food processor until fine crumbs form. Add melted butter; pulse until combined. Press onto bottom of a greased 9-in. springform pan. Refrigerate while preparing filling.
2. In a small saucepan, sprinkle 2 teaspoons gelatin over 1 tablespoon cold water; let stand 1 minute. Heat and stir over low heat until gelatin is completely dissolved; remove from heat.

Repeat twice with milk and white chocolates, keeping remaining whipped cream chilled until needed.
