Get out a high-speed blender and make sure it's large enough to fit all the ingredients. The filling yields about 5-6 cups. If your blender isn't big enough, a food processor will do - but it'll likely (it depends on your food processor) be creamier with a high-speed blender. Add all the filling ingredients, in the order listed (starting off with 1 cup (200 grams) of coconut sugar), and blend for about 30-60 seconds, or even longer, depending on your blender, or until totally smooth and no lumps of dates remain. Taste and add up to another 1/3 cup (66 grams) of coconut sugar, if desired.
3 cups (720 grams) warmed coconut cream, 1 cup (210 grams) pitted dates, 1 2/3 cups (183 grams) cocoa powder, 1 to 1 1/3 cups (200 to 266 grams) coconut sugar, 1/4 cup + 1 1/2 teaspoons (64 grams) coconut oil, 1 tablespoon vanilla extract, 1 teaspoon salt
