Step 1: Prepare the Graham Cracker Crust

Preheat the oven to 325°F (163°C) as a suggested starting temperature for this untested cheesecake recipe. Prepare your cheesecake pan according to your preferred cheesecake method.

Place the graham cracker crumbs in a mixing bowl and pour in the melted butter. Stir until the crumbs are evenly moistened and resemble damp sand. Transfer the mixture into the bottom of the prepared pan.

Press the crumbs firmly into an even layer using the back of a spoon or the bottom of a measuring cup. Make sure the crust reaches the edges and has a consistent thickness. Set it aside while preparing the filling.

Step 2: Make the Creamy Cheesecake Filling

Place the softened cream cheese in a large mixing bowl. Beat until smooth, scraping down the sides of the bowl as needed. Add the granulated sugar and all-purpose flour, then mix until evenly combined.

Add the vanilla extract and heavy whipping cream. Continue mixing until the filling looks smooth. Add the eggs one at a time, mixing gently after each addition until incorporated.

Avoid excessive mixing once the eggs have been added. Scrape the bottom and sides of the bowl to make sure the ingredients are evenly combined and no large pockets of unmixed cream cheese remain.

Step 3: Add the Christmas Tree Cakes and Assemble

Prepare the seven Little Debbie Christmas Tree Cakes for the filling. The supplied ingredient list does not specify whether they should be chopped, layered, or arranged whole, so choose a consistent approach based on the texture and appearance you prefer.

Gently incorporate the prepared cake pieces into the cheesecake mixture, or arrange them through the filling if you want more visible pieces in the finished slices. Avoid overmixing so the cake pieces do not completely break apart.

Transfer the cheesecake filling onto the prepared graham cracker crust. Spread it evenly with a spatula, smoothing the surface so the filling reaches the edges of the pan.

Step 4: Bake, Cool, and Chill

Bake in the preheated oven at the suggested starting temperature of 325°F (163°C). A general planning estimate is 60–75 minutes, but this is not a verified baking time for this particular recipe. The actual time will depend on the pan size, filling depth, oven, and arrangement of the Christmas Tree Cakes.

Watch the cheesecake as it bakes. The edges should look set, while the center may still have a slight wobble. Avoid waiting for the entire center to become completely firm in the oven, because cheesecake continues to set as it cools.

Once baked, allow the cheesecake to cool gradually. Refrigerate it after cooling and leave it until thoroughly chilled and firm. Allow approximately 6 hours for cooling and chilling as a planning estimate, adjusting as necessary for the actual cheesecake.

Step 5: Prepare the White Chocolate Ganache and Decorate

Place the white chocolate in a heat-safe bowl. Warm the heavy whipping cream until hot but not boiling, then pour it over the white chocolate. Let it sit briefly before stirring gently until the chocolate melts and the mixture becomes smooth.

If pieces of chocolate remain, warm the mixture gently in short intervals while stirring. Avoid overheating the white chocolate, as this can affect its texture.

Allow the ganache to cool slightly until it reaches a consistency suitable for spreading or pouring. Add it over the chilled cheesecake and spread carefully across the surface.

Finish with green sprinkles and red buttercream frosting. Arrange the decorations in a festive pattern, then refrigerate the cheesecake if the topping needs additional time to set. Slice and serve chilled.
