Lay the dough out and sprinkle the leavening agents on top. Add 1/2 of a teaspoon of salt, 2 teaspoons of baking powder, and 1 teaspoon of baking soda.
Knead the dough until well mixed.
Preheat your oven to 375 degrees and also preheat a cast iron skillet just until warm to the touch.
Roll the dough out to about 1/2 an inch thick. Using a biscuit cutter, cookie cutter, or a drinking glass, cut out your biscuits.
Arrange the biscuits in the skillet and allow them to sit out for about 15-20 minutes before baking for a better rise.
Transfer the biscuits to the oven. About halfway through. Baste the biscuits with the butter and return to the oven.
The biscuits should bake for about 20 minutes, or just until golden brown. If your biscuits are on the smaller side, you will only need to bake them for 15 minutes. Keep and eye on them so they don't get overdone and dried out.
Once the biscuits are done, remove them from the oven and baste with butter one more time.
Remove them from the skillet and serve!
