Preheat the oven to 400°F.
Stir the crust ingredients together in a large bowl.
Transfer the mixture to a 9-inch pie plate, then press it into the bottom and sides of the pie plate.
Place the pie plate into the oven and bake the pie for 8 to 10 minutes, until it darkens slightly. Place the pie plate on a cooling rack and let the pie cool completely.
Open the can of coconut cream, then transfer the solid portion to a large mixing bowl. Discard the liquid (coconut water), or save it for another use. Add the remaining filling ingredients to the bowl with the coconut cream.
Use an electric mixer at high-speed to beat the filling ingredients together until creamy, which should only take about a minute.
Transfer the filling to the cooled pie crust, smoothing the top out with a spatula.
Place the pie into the fridge to chill for at least three hours.
To make the ganache, first place the chocolate chips into a medium bowl.
Heat the coconut milk just to a simmer, either by microwaving it in a microwave safe bowl, or briefly heating it in a saucepan on the stove.
Pour the hot coconut milk over the chocolate chips. Let the mixture sit for 5 mintues.
After 5 minutes, begin stirring the coconut milk and chocolate chips together, until smooth and fully combined.
Pour the ganache over the peanut butter filling, then smooth it out with a spatula.
Place the pie back in the fridge to chill until fully set, about 3 hours.
Optionally, garnish the pie with whipped topping and peanut butter cups. Slice and serve.
