Preheat oven to 350°F (175°C).
In a small bowl, combine the melted butter, graham cracker crumbs and 1 tablespoon sugar. Press into the bottom of a 9 inch springform pan. Bake in preheated oven for 10 minutes. Allow to cool.
In a large bowl, cream the 3/4 cup of sugar and cream cheese together until smooth. Add eggs, one at a time, and vanilla. Stir in chopped candy bar, and pour into baked crust.
Bake at 350°F (175°C) for 45 minutes. Let cool and carefully remove the springform pans side.
