Make the Crust: Process the cookies in a food processor until ground into fine crumbs. Add the melted butter and pulse until the mixture is evenly moistened. (If you do not have a food processor, you can place the cookies in a zip-top bag and crush into crumbs with a rolling pin, then transfer to a bowl and stir in the melted butter.) Press the crumb mixture evenly and firmly into the bottom of a 9-inch springform pan; set aside.
Make the Cheesecake: Beat together the cream cheese and sugar on medium speed until smooth and creamy, scraping the sides of the bowl as needed, about 3 minutes. Add the eggs one at a time, beating well until fully incorporated and scraping down the sides of the bowl between each addition. Add the heavy cream and vanilla and beat until well combined, about 1 minute. Using a rubber spatula, fold in the chopped Snickers bars. Pour the batter on top of the crust and bake for 55 to 65 minutes, or until the edges are set, but the middle still jiggles a little.
Remove the cheesecake from the oven, and place the pan on a wire rack to cool completely. Once completely cool, refrigerate for at least 6 hours (preferably overnight).
Garnish the cheesecake with fresh whipped cream, more chopped Snickers bars and drizzles of hot fudge and caramel sauces. Leftover cheesecake can be stored, covered, in the refrigerator for up to 4 days.
