Preheat oven to 475 degrees.

Sift flour, salt and baking powder into a bowl. Grate chilled butter with a box grater. Add the butter and cheddar to the dry ingredients. Add the cold buttermilk to the flour butter mixture and stir until it forms a ball.

Turn out on a floured surface and knead just until it comes together. With a rolling pin, roll into a 3/4-inch thick rectangle. Fold into a smaller rectangle and repeat about 4 more times. This will give your biscuits the layered consistency we love. 

Cut out biscuits and place onto a lined baking sheet. Bake in the preheated oven for 15 minutes. While the biscuits are baking, melt the butter, garlic, and parsley together. Once the biscuits are done baking, brush the top of the hot biscuits with the garlic butter mixture and sprinkle with sea salt.
