In a food processor, combine walnuts, dates, and cocoa powder. Pulse several times until the mixture is crumbly and starts to stick together.
Lightly grease a pie plate with cooking spray or coconut oil. Press the crust mixture down into the pie plate and place in the freezer while you work on the filling.
Rinse out your food processor bowl and wipe dry. Place tofu in the food processor with maple syrup, cold brew concentrate, vanilla, and salt. Process until just combined.
Melt chocolate in the microwave (work in increments of 30 seconds then stir – this helps to ensure you heat it just enough to melt without burning it). Pour melted chocolate into food processor bowl with tofu mixture, and pulse several times until everything is well combined.
Remove the pie plate with your crust from the freezer. Pour the filling into the crust. You can place this in either the freezer or the fridge for about 2 hours to set. The freezer will produce more of a solid filling while the fridge will produce more of a pudding like filling.
