Heat the oven to 450 degrees F.
In a medium size bowl add flour, baking powder, baking soda, salt, and milk.
Using a cheese grater shred the butter and add it to the bowl. Cut the butter into the flour mixture with a fork and coarsely mix all ingredients.
Knead the dough just enough so that all ingredients are incorporated.
Sprinkle flour on a cutting board. Roll the dough on the cutting board so that it’s about 1 inch thick.
Using a biscuit or large cookie cutter, cut out as many biscuits as possible. Re-roll the dough to cut the remaining biscuits.
Grease a large iron skillet with butter. Lay the biscuits in the skillet tightly, side by side.
Using a spoon, add milk on top of each biscuit and spread it around the top.
Sprinkle the sugar evenly on top of each biscuit. Bake in a preheated oven until the top of the biscuits turn a golden color (about 10 to 12 minutes). Remove from the oven and let cool.
