12 cups all-purpose flour
1 tablespoon baking powder
1/2 teaspoon baking soda
3/4 teaspoon salt
1 teaspoon sugar
1/2 teaspoon garlic powder
1 stick unsalted butter
1 cup cheddar cheese, grated
1/4 cup parmesan, grated
1 cup buttermilk
4 tablespoons butter, melted
Heat the oven to 350 F and line a sheet pan with parchment paper.
Blend the flour, salt, sugar, baking powder, baking soda, and garlic powder into a large bowl
With your fingers, blend the butter into the dry ingredients until it resembles coarse sand with pea sized lumps of butter in it. Stir in the shredded cheeses
Make a well in the center of the dry ingredients and pour the buttermilk in. With a spoon, gently mix until the dry ingredients are just moist. Do not overmix.
Scoop the biscuits onto the parchment line sheet (roughly 1/3 cup – I used a large disher) and bake for 12 to 15 minutes. The tops will be pale, but the bottoms will be lightly golden brown
Brush the tops with the melted butter and place under the broiler for 1 to 2 minutes, or until the tops become golden.
