Preheat your oven to 325°F (163°C).
Prepare the crust by mixing the crushed graham crackers and melted butter in a bowl.
Divide the crust mixture among a lined muffin pan, pressing it firmly into the bottom of each cup.
Bake the crust in the preheated oven for 5 to 7 minutes or until slightly golden.
While the crust bakes, beat the softened cream cheese and sugar together in a mixing bowl until smooth and creamy.
Add in the eggs one at a time, mixing well after each addition, then stir in the vanilla extract.
Pour the cheesecake filling over the baked crust in each muffin cup, filling them about 3/4 full.
Bake for 20-25 minutes, or until the edges are firm but the centers still jiggle slightly.
Remove from the oven and allow them to cool in the pan for 10 minutes, then transfer to a wire rack to cool completely.
Melt the green candy melts according to package instructions and drizzle over the cooled cheesecakes to form trees.
Add candy decorations of your choice to complete the Christmas tree look.
Refrigerate the cheesecakes for at least 2 hours before serving to allow them to firm up.
