Preheat your oven to 325°F (162°C). Line a cupcake pan with cupcake liners and spray with nonstick spray.

In a mixing bowl, combine crushed Oreo cookies with melted butter. Divide among cupcake cups and press down to create a crust. Bake for 5 minutes and cool.

Lower the oven temperature to 300°F (148°C). Beat cream cheese, sugar, and flour on low until smooth and creamy, about 2-3 minutes.

Mix in sour cream and vanilla, then add eggs one at a time, mixing slowly after each addition.

Divide the mixture into three bowls. Tint one yellow, one orange, and leave one white with gel food coloring.

Layer the colored batters into the crusts: yellow, then orange, then white, filling nearly to the top.

Bake for 15 minutes, then turn off the oven and leave cheesecakes inside for 10 minutes.

Transfer to the refrigerator and chill for at least 2 hours.

Whip heavy cream, sugar, and vanilla until stiff peaks form for topping.

Dollop or pipe whipped cream on top and add Halloween decorations. Serve and enjoy!
