Preheat the oven to 325°F (165°C) and line a 12-cup muffin tin with cupcake liners.
Combine the graham cracker crumbs, granulated sugar, and melted butter in a medium bowl, mixing until the crumbs are evenly coated.
Press the crumb mixture evenly into each liner, using the back of a spoon to create a firm crust. Bake for 5 minutes, then set aside to cool slightly.
Beat the softened cream cheese in a large bowl with an electric mixer until smooth. Add granulated sugar and mix until well combined.
Add the eggs one at a time, mixing well after each. Stir in vanilla extract and sour cream until smooth and creamy.
Divide the batter into three bowls, tinting one yellow, one orange, and leaving the last plain. Layer the batters into each crust: yellow first, then orange, then plain.
Bake for 18–20 minutes, or until centers are set. Cool in the pan for 30 minutes, then refrigerate for at least 4 hours or overnight.
Frost the chilled cheesecakes with orange-tinted buttercream, sprinkle with white sprinkles, and top each with a sugar paste ghost before serving.
Notes
Chef Jenn’s Tips
Gel food coloring keeps the batter thick and colors vibrant.
Let the cheesecakes chill completely before frosting for a cleaner finish.
A piping bottle can make frosting easier to apply neatly.
Store fondant decorations separately and add them just before serving.
