If you want to make this pie with fresh sweet potato, then start by boiling the sweet potatoes. If you want to skip this step, you can use pumpkin puree from a can.
To boil the sweet potatoes, peel them and poke holes all over them. Then place them in a pot of boiling water until they are soft enough that you can easily stick a fork into them.
Once the potatoes are ready, let them cool off and mash them with a fork.
In a large bowl, add the sweet potatoes (or pumpkin puree). Then add the coconut cream, maple syrup, coconut sugar, corn starch, vanilla, allspice, cinnamon, ginger, and a pinch of salt.
Use a hand mixer or immersion blender to mix all of the ingredients well until you get a thick, smooth, and creamy pie filling.
Pour the pie filling into the pie crust.
Bake the pie for 50-60 minutes at 350 degrees Fahrenheit.
