1-First, preheat the oven to 350°F and prepare the graham cracker crust in a springform pan, then chill it in the refrigerator to set.

2-Next, in a large bowl, beat the 24 ounces of cream cheese with the ¾ cup brown sugar and ½ cup sugar until smooth and free of lumps. This step is crucial for that creamy texture everyone loves.

3-Keep going by stirring in the ⅓ cup sour cream, 1 ½ teaspoons vanilla extract, 1 cup pumpkin puree, and 2 ½ teaspoons pumpkin pie spice until well combined. Add the 3 large eggs one at a time, mixing gently after each addition to avoid overbeating. Spread the cheesecake batter evenly over the prepared crust, place the pan on a foil-lined baking sheet, and bake for 40 minutes, or until the center is almost set with a slight jiggle while the edges are firm.

4-After baking, let the cheesecake cool to room temperature, then chill it in the refrigerator for at least 6 hours or overnight. For the topping, combine the ¾ cup heavy cream, ¼ cup powdered sugar, ½ teaspoon vanilla extract, and ⅛ teaspoon ground cinnamon in a clean bowl; whip with a mixer until stiff peaks form, then top the chilled cheesecake. Remember, patience during cooling helps keep things crack-free, just like in other desserts you might try from our site.
