Crush the chocolate sandwich cookies in your blender and add the melted margarine, pulsing to combine completely.
Press the cookie crumb mixture into the bottom and up the sides of a 9-inch spring form pan lined with parchment paper (for easy removal of the cheesecake later on!)
Chill the crust to set while you make the filling.
To a clean blender add the silken tofu, maple syrup, vanilla extract.
Melt the chocolate in a double-boiler over low heat, or melt it in the microwave at 50% power for 30-second increments until the chocolate is melted and smooth.
Let the chocolate cool slightly before adding it to the blender with the other ingredients. This will ensure a smooth texture.
Blend until very smooth, scraping down the sides of the blender if necessary.
Pour the filling into the chilled crust and smooth out the top with a rubber spatula.
Place the cheesecake in the fridge to chill for at least 6 hours, or overnight, before transferring to a plate to slice and serve.
Serve with fresh berries, powdered sugar, or your favourite vegan whipped cream.
