It's hard to believe something so good for you—with zero added sugars and unnatural ingredients—can taste so sinful. (They also happen to be quite a bit less expensive than Jocalats, Nectars, and many other such chocolate bars.)
1 c walnuts (120 grams)
1 and 1/3 cups pitted dates (220 grams) (I often use SunMaid dates, which are super-soft.)
1 tsp vanilla extract
optional: 1/8 plus 1/16 tsp salt (I always add this.)
3-4 tablespoons cocoa powder (or even Dutch cocoa)
Blend all the ingredients, using a food processor, Magic Bullet, etc. (No need to blend the dates first; I just blend everything all at once in a Cuisinart food processor, which works much better than a blender.) Roll into cutey-pie little balls. (Use plastic wrap if you wish, or smush it all together in a plastic bag so it'll stay together better.) Or, if you want true brownies, shape the dough into bars!
