Preheat your oven to 350°F.
In a blender or food processor, combine the pumpkin purée, silken tofu, brown sugar, maple syrup, cornstarch, pumpkin pie spice, vanilla extract, and salt. Blend until the mixture is smooth and creamy.
Taste the filling and adjust spices or sweetness to your preference.
Pour the pumpkin mixture into the pre-made vegan pie crust, using a spatula to smooth the top.
Place the pie on the middle rack of the oven and bake for 50-60 minutes, or until the center looks set but still has a slight jiggle.
Remove from the oven and let the pie cool completely on a wire rack. This helps the filling set. Once cool, refrigerate for at least 2 hours, or overnight for best results.
Serve chilled with a dollop of coconut whipped cream and a sprinkle of pumpkin pie spice if desired.
