Prep oven by preheating it to 350 degree Fahrenheit. Line a baking pan with parchment paper. I used a 9 x 13 baking pan.
Use a food processor to turn your cinnamon graham cracker into crumbs. You will need 1 1/2 cups of crumbs. If you do not have a food processor you can place your graham crackers into a zip lock bag and crush the graham crackers into crumbs.
In a large bowl, combine 1 1/2 cups of cinnamon graham cracker crumbs and 5 tablespoons of white granulated sugar together. Melt 5 tablespoons of butter. Add the melted butter into your crust mixture. Combine well. Pour the crust mixture into your lined baking pan and pack down the crust.
Now to prep the pumpkin filling. In a large bowl, add one can of pumpkin pie mix, 1/3 cup of evaporated milk, and 1 whole large egg. Use an electric hand mixer to mix well. Once your pumpkin mixture is smooth, pour it on top of the crust in your lined baking pan.
Now to prep your cheesecake filling. In a large bowl, use an electric hand mixer to mix 1 package of 8oz cream cheese, 1 whole large egg, 1 large egg yolk, 1/2 cup of white granulated sugar, and 1 teaspoon of vanilla extract together until smooth. Pour the cheesecake filling on top of the pumpkin filling.
Bake in your preheated oven for 42 mins. Let cool before serving.
