Note if your dates are quite dry, you should soak them in hot water for 10-15 minutes then drain well before use. If your dates are soft, proceed with the recipe. Add the walnuts to a food processor and process to break down into a coarse, grainy four with some small pieces.
1.5 cup raw walnuts
Add the rest of the ingredients except for the chocolate and process again until it forms a thick, sticky dough.
2.5 cups loosely packed soft pitted dates, 1/2 cup cocoa powder, 1 tbsp maple syrup, 1/2 tsp sea salt, 1 tsp vanilla
Add the chocolate and pulse a few times to mix it into the dough.
1/2 cup dairy-free chocolate chunks or chips
Line a standard-sized loaf pan with two overlapping strips of parchment paper that are long enough to stick out either side of the pan. Firmly press the dough into the pan, taking a few minutes to work it into every corner and smooth it out.
Place in the fridge for a few hours or the freezer for about an hour.
Lift and cut into 10 bars.
