OK, I'm back with the results... needed to increase the cocoa powder to 1/2 cup (and next time I'll cut the sugar back to 2 cups.) Used 1 stick butter, 12 oz. can evaporated milk, salt and vanilla. I mixed the dry ingredients in a bowl and set aside. Melted the butter in the bottom of a sauce pan, & added the milk. Slowly added the dry ingredients stirring well as I added them. Cooked over med heat, stirring often, until it came to a rolling boil; then boiled it for 2-3 minutes, stirring constantly. Its too sweet for my taste, buy other than that its good. Thanks again.
