Ingredients
  

  • 2 1/4 cups Graham Cracker Crumbs
  • 1 tablespoon Light Brown Sugar
  • 1 teaspoon Cinnamon
  • 1/2 cup Unsalted Butter melted
  • 6 ounces White Chocolate melted
  • 1 tablespoon Cold Water
  • 1 teaspoon Unflavored Gelatin
  • 1 cup Heavy Whipping Cream
  • 3 tablespoons Powdered Sugar
  • 4 ounces Cream Cheese softened
  • 8 ounces Mascarpone Cheese cold
  • 1 cup Heavy Whipping Cream
  • 1/2 cup Powdered Sugar
  • 2 tablespoons Light Brown Sugar
  • 1/4 cup Pumpkin Puree
  • 1 teaspoon Pumpkin Pie Spice
  • 3/4 cup Heavy Whipping Cream
  • 3-4 tablespoons Powdered Sugar
  • Pecans optional

Instructions
 

  • Line the bottom of a 9-inch (22.8-cm) springform pan with parchment, wrapping around the removable bottom of the pan.
  • Grind the graham crackers into fine crumbs using a food processor or blender.
  • In a microwave-safe bowl, combine graham cracker crumbs with the brown sugar, cinnamon and melted butter. Stir the melted butter into the crumbs until there are no dry crumbs left.
  • Pour the crumbs into your springform pan and press firmly into the bottom and up the sides of the pan to create a thick crust. Refrigerate the crust while you are preparing the filling.
  • Place the mixing bowl and whisk attachment in the freezer for 5 to 10 minutes to chill while you are preparing the next steps.
  • Place 1 tablespoon of cold water in a small dish. Sprinkle the powdered gelatin over the water, spreading evenly. Allow the gelatin to turn to a solid (about 2-3 minutes)
  • In a microwave-safe bowl, microwave the white chocolate at 50% power in 30-second increments, stirring each time until the chocolate is melted and smooth. Set aside.
  • Next, melt the gelatin in the microwave for 5-8 seconds until it turns back to a liquid. Watch it closely!
  • Pour the heavy whipping cream into the chilled bowl and use an electric mixer to beat the heavy cream on medium-high speed until the cream starts to thicken.
  • Slowly add the powdered sugar and liquid gelatin and continue beating on high speed until stiff peaks form. Set the whipped cream aside.
  • Soften the unwrapped cream cheese in the microwave for 15 seconds. Change the mixer to the paddle attachment and beat the cream cheese until it’s completely smooth.
  • Scrape down the sides of the bowl, and add the melted chocolate, beating until it’s completely mixed into the cream cheese.
  • Lastly, fold in the prepared whipped cream and mix until all ingredients are combined. Pour the filling into the prepared crust, spread evenly. Set aside.
  • Place mixing bowl in the freezer for 5 minutes to chill. Beat the mascarpone at a low speed, slowly adding heavy cream (scrape down the bowl as needed) until mascarpone resembled a liquid mixture and add all remaining heavy cream.
  • Increase speed to medium-high beating until cream gets bubbly. Slowly add the powdered sugar, brown sugar and pumpkin pie spice and continuing beating until soft peaks form.
  • Slowly add the pumpkin puree and continue beating until stiff peaks form. Pour the filling over the white chocolate layer, spread evenly. Cover and refrigerator 3-4 hours.
  • Prepare another batch of whipped cream by placing your bowl in the freezer for 5-10 minutes. To prepare the whipped cream, pour the heavy whipping cream into the chilled bowl and use an electric mixer to beat the heavy cream on medium-high speed until the cream starts to thicken. Slowly add the powdered sugar and continue beating on high speed until stiff peaks form.
  • Pipe the borders of the pie with whipped cream using alarge open round tip. Garnish with pecans. Store covered in the refrigerator.
