Preheat oven to 325°F and set aside a lined baking sheet.
Mix together date paste, nut butter, and vanilla until a smooth paste forms.
Add remaining ingredients, except chocolate, and mix until evenly combined. You may want to use your hands to mix the date mixture into the oat mixture.
Spread granola out onto the lined baking sheet, using your hands or a spatula to press the granola down flat. Bake 20-25 minutes, stirring halfway through, then remove from oven, mix in chocolate, and let cool completely.
Store leftovers in an airtight container. Enjoy!
Notes
*To make the date paste, blend 1-4 tbsp water with about ¾ cup of pitted dates. The amount of water you need will depend on how dry your dates are, so start with 1 tbsp and add more as needed. You want to end up with ¾ cup of date paste. The final date paste should still be thick (but stirrable) and not runny.
