Creating your Eggnog Cheesecake is simple if you follow these outlined steps:

1. Preheat Oven: Preheat your oven to 325°F (160°C). Grease a 9-inch springform pan.
2. Prepare Crust: In a bowl, combine the graham cracker crumbs, melted butter, and ⅓ cup sugar. Mix well until the crumbs are fully coated.
3. Form Crust: Press the mixture firmly into the bottom of the prepared springform pan. Bake for 10 minutes, then remove from the oven to cool.
4. Mix Cream Cheese: In a large mixing bowl, beat the softened cream cheese until smooth using an electric mixer.
5. Add Sugar and Eggnog: Gradually add in 1 cup of sugar and beat until well combined. Slowly mix in the eggnog until the mixture is smooth and creamy.
6. Add Eggs: Add the eggs one at a time, mixing gently after each addition until just incorporated.
7. Mix in Flavors: Stir in the vanilla extract, nutmeg, cinnamon, and flour until the mixture is fully combined.
8. Pour into Pan: Carefully pour the cheesecake filling into the cooled graham cracker crust, smoothing the top with a spatula.
9. Bake Cheesecake: Bake in the preheated oven for 55-60 minutes, or until the center is set but slightly jiggly.
10. Cool Down: Turn off the oven and leave the cheesecake inside with the door slightly ajar for 1 hour to cool gradually, then transfer it to the refrigerator to chill for at least 4 hours or overnight.

These simple steps will guide you toward crafting a heavenly Eggnog Cheesecake that everyone will adore.
