Step 1: Prepare the Crust - Place the raw walnuts in a food processor and pulse until resembling a fine meal. Add medjool dates, cacao powder, and kosher salt. Process until the mixture sticks together. Add water if too dry.
Step 2: Form the Crust - Transfer the crust mixture into a 9-inch pie dish and press it evenly into the bottom and sides. Set aside.
Step 3: Make the Filling - Combine dairy-free chocolate chips, silken tofu, non-dairy milk, brewed coffee, vanilla extract, and kosher salt in the food processor. Blend until smooth.
Step 4: Assemble the Pie - Pour the filling into the prepared crust and smooth the top. Tap the dish to remove air bubbles. Cover and refrigerate for at least 4 hours.
Step 5: Serve and Enjoy - Remove from refrigerator, add toppings if desired, slice, and serve.
