Preheat the oven: to 325°F. Grease a 9-inch springform pan or line with parchment paper.
Prepare the crust: In a bowl, mix the gluten-free graham cracker crumbs with melted butter and monk fruit sweetener.Press the mixture into the bottom of the prepared springform pan, creating an even layer. Set aside.
Make the cheesecake filling: In a large bowl, beat the cream cheese until smooth. Add the pumpkin puree, monk fruit sweetener, eggs, vanilla, and spices. Mix until fully combined.
Assemble the cheesecake: Pour the filling over the prepared crust and smooth the top with a spatula.
Bake: Place the cheesecake in the oven and bake for 55-60 minutes, or until the center is set but still slightly jiggly.
Cool: Turn off the oven, crack the door open slightly, and allow the cheesecake to cool for an hour inside. Then transfer it to the fridge to chill for at least 4 hours or overnight.
Serve: Once fully chilled, carefully remove the cheesecake from the springform pan. Top with whipped cream (if desired) and a sprinkle of cinnamon.
