3-Ingredient Biscuits

0 Place 1/4 cup of the butter (4 tablespoons) into a cast iron skillet and put in a cold oven.
1 Preheat oven to 425 degrees F with the skillet inside.
2 Add the self-rising flour to a large mixing bowl.
3 Grate cold butter into the flour, stopping to stir gently occasionally.
4 Add in the Sprite and mix to form a dough. Stop mixing once all ingredients are combined. If the dough is dry and not coming together add more Sprite a tablespoon at a time, mixing gently.
5 Sprinkle flour generously over a working surface. Place the dough on the surface and gently pat into a  3/4 to 1-inch thick round.
6 Cut into biscuits of your desired size. I used a clean, empty tomato paste can and got 15 biscuits.
7 Place the cut-out dough close together in the hot skillet.
8 Bake in preheated oven for about 12 to 15 minutes until they are 195F in the center.
9 Remove and let cool for just a few minutes to firm up.
10 Brush tops with honey butter, or butter if desired.
