Preheat your oven to 450 degrees for a cast iron skillet. Or 400 degrees for a metal or glass baking dish.

Then grease your cast iron skillet or baking dish.

In a bowl add your granulated sugar and 2 cups of self-rising flour. Give it a mix.

Stir in your buttermilk and mix until the batter comes together like biscuit dough. If too dry, add a bit more buttermilk to the batter.

Now gently fold in your blackberries.

Turn the dough out on a lightly floured surface. Sprinkle some of the remaining flour on the counter. Then work the dough by kneading it. You can add a little more flour if it is too sticky.

Roll the biscuit dough out with a rolling pin to around 1-inch thickness.

Then cut biscuits with 2 1/4 inch round cutter. Then place the biscuits in a skillet making sure the biscuits touch.

Place biscuits in a preheated oven in the center rack. Cook for 12-15 minutes or until the tops are golden brown and biscuits are cooked through.

Once you remove from the oven spread your melted butter over the tops of the blackberry biscuits and serve up warm biscuits.

I dusted with sugar and served up the cast iron blackberry biscuits.
