6 Tbsp butter
2 Cups flour
1 Tbsp sugar
1/4 tsp baking soda
1 Tbsp baking powder
1 tsp salt
1 Cup buttermilk
Preheat oven to 450 degrees.
Cut butter into small cubes, place on a plate, and place in the freezer while you mix the dry ingredients.
In a food processor, sift together flour, sugar, baking soda, baking powder, and salt.
Add the cold butter to the food processor and pulse to combine, until it looks like coarse crumbs. Pour into a large mixing bowl.
Make a well in the center of the flour/butter mixture. Add the cold buttermilk and stir until dough is mixed and combined. It will be slightly sticky/tacky. If it is VERY sticky, add a tiny bit more flour.
Turn dough out onto floured surface and pat into a rectangle. Fold the dough over and onto itself six times, so you end up with a tall square, then pat down to about 1 inch thick. With a 2.5 inch round biscuit cutter, push down through the dough and pull straight up (DO NOT TWIST THE CUTTER!). Place biscuits on cookie sheet lined with parchment paper, almost touching each other.
Bake at 450 degrees for 12-15 minutes until browned. After they are baked, brush with melted butter.
