• Combine the cream cheese and powdered sugar in a large bowl, mixing with a hand mixer on medium speed (or in your stand mixer) until smooth. 
• Add the red food colouring paste and mix well until incorporated, scraping down the sides of the bowl to ensure everything is incorporated and the colour is distributed evenly.
• Add the melted white and semi sweet chocolate in a steady stream while the mixer is running on low speed, until completely incorporated. Scrape down the sides of the bowl to be sure everything is incorporated.
• Fold in the whipped cream or whipped topping by hand until the mixture is fluffy and creamy and there are no streaks of white in the batter.
• Pour the cheesecake mixture into the prepared crust and smooth out the top with a rubber spatula or offset spatula.
• Refrigerate to set for 6 hours or overnight, or set in the fridge for 2-3 hours and then in the freezer for 2-3 hours before serving. OR, set in the freezer only for 3-4 hours.
