Preheat oven to 450 degrees F.

Add self-rising flour, garlic salt, and granulated sugar to medium sized bowl and whisk together to combine.

Grate frozen shortening with a cheese grater right into the flour mixture. Add two tablespoons of broken up herb goat cheese into the flour mixture (easily break the cheese apart with your hands). Begin cutting the shortening and goat cheese into the flour using a pastry cutter.

Sprinkle in shredded mixed cheeses and combine with biscuit mixture.

Add cold milk to the biscuit mixture and using a spoon, quickly fold into the biscuit mixture. A wet dough should form.

Place the biscuit dough into the refrigerator for 15 minutes.

After 15 minutes, sprinkle flour on your working area or board and remove biscuit dough from bowl. Use your hands to flatten the dough and shape out to your preferred thickness of 1/2-3/4 inch.

Cut biscuit dough into circles using round cutter or back of a can.

Place cut biscuits onto greased cast iron skillet and bake for about 10-12 minutes or until they have risen and browned.

Optional: To make biscuits a bit browner, turn the broiler on until you get them as brown as you would like on the top.

Lastly, add garlic salt and parsley to melted butter and mix together. Brush herb butter on the tops of biscuits after removing from the oven and serve warm.
