3 1/2 cups All Purpose Flour
1/2 teaspoon Salt
3/4 cup Unsalted Butter, cold, cut into cubes
1 3/4 cups Cheddar Cheese, Grated, plus more for topping
1 cup plus 1 tablespoon Milk
Preheat oven to 400 degrees Fahrenheit.
Combine flour, salt, and cheddar in the bowl of a stand mixer. With the paddle attachment, mix for 30 seconds. Add the cold butter cubes, mix until hazelnut sizes crumbs of butter are left in the flour. Pour in the milk, mix until just combined. Do not over mix. On a lightly floured surface, roll biscuit dough to 1/2 inch thick. Cut biscuits using a round cutter, placing on a parchment lined baking sheet. Refrigerate the biscuits for 10 minutes. Make an egg wash by beating 1 egg with 1 teaspoon cold water.
Brush with tops of the biscuits with egg wash and place in the oven. Bake for 8-10 minutes until light golden. Remove biscuits, brush again with egg wash and top with additional cheddar cheese. Place in the oven for 1-2 more minutes until cheese melts and turns golden brown.
