In a food processor, process the Oreos until crumbly. The add in the melted butter and process again for a few seconds until mixed. Press this mixture into the bottom of a 9 inch springform pan. Freeze for 10-15 minutes.
Place the sliced bananas in a single layer on top of the crust. Then start with the chocolate ice cream layer. Be sure the ice cream is softened before trying to spread it on the crust. Spread the chocolate layer evenly on top, and then freeze for 1 hour. Repeat with the strawberry layer and then vanilla layer, freezing an hour in between layers.
Once completely frozen, add on your toppings and enjoy!!
