Wisk together 1 cup sugar, pinch of salt, self rising flour, and milk.
Add melted butter and combine well.
Pour mixture into baking dish.
Distribute blackberries (that have been rinsed and dried) over top of mixture evenly.
Sprinkle remaining ⅓ cup of sugar evenly over the top.
Bake for 40-50 minutes or until edges are browned and blackberries are bubbly. Be sure to check this dish frequently towards the end, cooking time will depend on size of baking dish. I used a 9x13 for a thinner blackberry buckle and cooked for about 45 minutes.
