Recipes look bomb, but no hash in the hash brownies!
If you wanted to make true hash brownies it's very simple. Take your hash (full melt works best for this) and dissolve into the butter/oil. Gently heat the oil while stirring so the hash dissolves easier. I personally use coconut oil since it has a very high saturated fat content (easier for THC to bond to). Coconut oil can also be freely substituted for butter in most recipes.
