Place 2 Tbsp butter into cast iron pan or oven safe pan and allow butter to melt and begin to brown as the oven preheats. Watch it though so the butter doesn't burn, you want the butter to be a light golden brown.
Mix together flour, baking powder, salt , and baking soda in a bowl. Cut in the chilled butter until mixture resembles coarse crumbs.
Stir in milk gradually until the dough pulls away from the bowl and comes together. You may need more or less than the amount called for. Handle the dough as little as possible, don't knead.
Place dough onto a lightly flowered surface and pat dough out to 1 inch thick. Use a biscuit cutter or round cutter to cut biscuits.
Dip top and bottom of biscuit into browned butter and place into dish.
