Preheat the oven to 350°F (180°C). Line a 9 inch springform pan with parchment paper. Prepare The Crust: Crush the graham crackers in a food processor, then combine them in a bowl with melted butter and sugar. Stir the mixture together.
Prepare The Cheesecake Filling: In a stand mixer fitted with a paddle attachment, beat the cream cheese and sugar on high speed until creamy. Add eggs one at a time, mixing between each addition until just incorporated.
Bake The Cheesecake: Prepare a water bath by placing a roasting pan in the oven and placing the cheesecake pan in the middle of it. Pour boiling water around the cheesecake until 1 inch deep. Bake for 55-60 minutes.
Prepare The Ganache: In a saucepan, heat the cream until hot but not boiling. Pour over the chocolate chips and let sit for 2 minutes. Stir well until smooth. If needed, whisk vigorously to bring it together.
To pipe whipped cream rosettes, first fill a piping bag fitted with a star tip halfway with the whipped cream. Then, holding the bag at a 90-degree angle, gently squeeze to make small circles, releasing pressure and lifting away to complete each rosette.
