Preheat oven to 425°F. Butter baking pan or skillet.
In a large bowl, whisk together the flour and sugar. Cut in the cold butter with a fork or pastry blender. Add the cheese and stir. Add the buttermilk and stir with a sturdy spoon until well combined.
On a floured surface, flatten the dough out to 1/2-inch thickness, fold in half and then in half again.
Cut dough into rounds or squares. (I made four large biscuits.) Place biscuits about an inch apart on the buttered skillet.
Bake for 20-25 minutes or until biscuits have risen and are light brown on top.
