Use an 8" springform pan for best results. Lightly grease it or line the bottom with parchment paper for easy removal.
Add the pecans, dates, almond flour, coconut flakes, coconut oil, vanilla, pumpkin pie spice, and cinnamon to a food processor.
Blend until the mixture sticks together, but stop before it turns into a paste.
Press the crust mixture evenly into the bottom of the pan. Use your fingers or the back of a spoon to pack it tightly.
Place the pan in the freezer while you prepare the filling.
Drain the soaked cashews and add them to a high-speed blender or food processor with the pumpkin puree, coconut cream, coconut oil, agave, lemon juice, vanilla, and spices.
Blend until smooth and creamy, scraping down the sides as needed.
Pour the filling over the frozen crust and smooth the top with a silicone spatula. Cover the pan with foil or plastic wrap.
Freeze for at least 4 hours or until firm. For the best texture, freeze overnight.
To serve, let the cheesecake thaw in the fridge for 1–3 hours or at room temperature for about 20 minutes.
