When we were finally ready to move beyond apartment living, we found that we owned wild black raspberry bushes. Except that I thought they were blackberries. Normally, I'm really good at noting where my recipes come from, but, at the time, I was just eager to use up the quarts and quarts of berries. I simply went on the internet and found one. My apologies to the owner! This one is EASY, and, yes, it works just great with black raspberries! There were some problems with the recipe though (missing cook time), so I found a similar one on the Pioneer Woman's website (Blackberry Cobbler 1)
In bottom of baking pan or large baking dish, melt butter. Add milk, but do not stir. Sift flour and sugar and add to dish but do not stir. Add berries. Bake at 350*F, for one hour or until crust rises to top and browns.
***Note -- I tried mixing it all together once and it didn't not turn out nearly as good. Maybe try mixing all but the berries, but those have to go on top LAST and NOT mixed in!
