1/3cupbutter (salted)chilled and cut into small cubes (for the dough)
1teaspoonbutter for greasing the skillet
For the Cinnamon and Sugar Coating:
8-inch size iron skillet
3-inch size biscuit or cookie cutter
For the Dough:
Preheat the oven to 450 degrees F.
Grease the skillet with butter and set aside. To a large bowl, add the flour, baking powder, salt, milk, sugar, cream of tartar, egg, and chilled, small cubes of butter. With a pastry cutter or a large sturdy fork, cut the butter into the ingredients. Continue to mix the ingredients together with the fork until dough forms.
Sprinkle a light coating of flour on to a large cutting board and add the dough. Knead the dough a few times until the texture becomes sturdy enough to roll. Add a light coating of flour to a rolling pin and roll out the dough until it’s about 1-1/4 inches thick. Using a 3-inch wide biscuit or cookie cutter, cut the dough into 4 large biscuits.
For the Cinnamon & Sugar Coating:
In a small bowl, mix together the cinnamon and sugar. Coat all sides of a biscuit with the cinnamon and sugar mixture and place it in the skillet. Repeat for the remaining 3 biscuits so that each biscuit is leaning against one another.
Bake in a preheated oven (at 450 degrees F.) until the biscuits turn a light golden color (about 16 minutes). Remove the biscuits from the oven and serve warm, topped with butter.
