Karen,
The closest thing I can think of is any of the cocoa-based Larabars (which I think now are called Jocolat). Those are raw and very nice and dense.
On the other hand, this is a recipe, EXTREMELY detailed for cocoa-laden muffin things that, while called brownies, really aren't unless you're so desparate for chocolate that they will do in a pinch. Their claim to fame is to have 10% or more of darn near every RDA nutrient for each 100 calorie brownie.
I've made them and they are chocolatey and pretty tasty, but I would not pass them off as brownies.
With that lengthy caveat, here is the recipe:
