Preheat the oven to 350°F (175°C).
On a lightly floured surface, roll out the pie crust dough to fit a 10-inch (25 cm) pie dish.
Transfer the dough to the dish, trim the edges, and crimp as desired. Keep the formed pie crust in the refrigerator until you are ready to fill and bake it.
In a food processor or blender, mix together the pumpkin purée, coconut cream, brown sugar, cinnamon, allspice, nutmeg, cardamom, cloves, molasses, vanilla, cornstarch, and salt until smooth.
Pour the filling into the prepared crust and smooth the surface with an offset spatula.
Bake for 55-60 minutes, until the filling is set and the crust is golden. Remove from the oven and cool completely at room temperature, then refrigerate for at least 4 hours before slicing.
Serve slices topped with whipped cream and a light dusting of cinnamon.
