1️⃣ Make the crust: In a medium bowl, combine graham cracker crumbs, sugar, and melted butter. Stir until the crumbs are evenly moistened.
2️⃣ Press & chill: Press the mixture firmly into the bottom of a 9-inch springform pan, or divide into dessert jars for individual servings. Chill while preparing the filling.
3️⃣ Prepare the filling: In a large mixing bowl, beat softened cream cheese until completely smooth. Add pumpkin purée, powdered sugar, pumpkin pie spice, and vanilla extract. Beat again until creamy.
4️⃣ Whip the cream: In a separate bowl, whip the heavy cream until stiff peaks form.
5️⃣ Fold together: Gently fold the whipped cream into the pumpkin mixture until fully blended and airy.
6️⃣ Assemble: Spread the pumpkin filling evenly over the chilled crust, smoothing the top. Cover and refrigerate for at least 6 hours or overnight until set.
7️⃣ Garnish & serve: Top with whipped cream and a sprinkle of cinnamon before slicing. Serve chilled and enjoy!
