Line a 9-inch (23 cm) springform pan or pie pan with parchment paper.
To make the crust, in a food processor, combine the flour, cocoa powder, maple syrup, and oil. Blend until crumbly and well mixed. If the mixture doesn’t hold together when pinched between your fingers, add up to 1 tablespoon (15 ml) additional oil.
Use your fingers to press the mixture evenly into the bottom and about halfway up the sides of the pan. Place the pan in the freezer while you make the filling.
To make the filling, combine all the filling ingredients in a food processor and blend until completely smooth.
Pour the filling into the prepared crust and refrigerate or freeze for 4 hours, or until firm.
To make the drizzle, in a microwave-safe bowl, combine the chocolate chips and oil. Microwave for 30 seconds, then stir. If not completely melted, microwave again for 10 seconds at a time until melted.
Drizzle the melted chocolate over the top of the pie and sprinkle with the crushed peanuts.
