Preheat your oven to 325°F and grease a 9x13 inch baking dish.
In a medium bowl, mix the graham cracker crumbs and melted butter. Press this into the bottom of your baking dish to form the crust.
In another bowl, beat the cream cheese until smooth. Add sugar and vanilla, mixing until combined.
Add the pumpkin and spices (cinnamon, nutmeg, cloves, salt), and beat until smooth again.
Crack in the eggs one at a time, mixing after each.
Pour the filling over the crust and spread it evenly.
Bake for about 50-55 minutes, or until the center is set and doesn’t jiggle.
Let cool completely at room temperature, then refrigerate for at least 4 hours (overnight is even better).
Slice, serve, and if you’re feeling fancy, top with whipped cream and a sprinkle of cinnamon.
