In a food processor, pulse the crust ingredients until a "dough" consistency forms and the dates are chopped fine.
Line a 12-cup muffin tin with paper cups, then scoop about 1 Tbsp of the dough into each cup. Use your fingers or the back of a spoon to press the crust into the bottom and slightly up the sides.
Rinse out the food processor, then work on your filling. Combine all of the filling ingredients, pulsing until super smooth. Spoon the mixture evenly into each of the 12 cups. Top with fresh berries, arranging them as you like. Drizzle lightly with honey or maple syrup.
Transfer the tarts to the freezer for about 1 1/2 to 2 hours, or until they are firm. Store in the refrigerator. Serve chilled.
