Place a large mixing bowl, box grater, and butter in the freezer for 15-30 minutes prior to making biscuits.

Preheat the oven to 425°F and place a 10-inch cast-iron skillet into the oven to preheat.

In the chilled mixing bowl, add 2 cups of self-rising flour, garlic powder, and Old Bay seasoning. Whisk until evenly combined. Set aside.

Use a box grater to grate your frozen butter.

Add the grated butter into the flour mixture and stir until combined. Then, stir in the shredded cheddar cheese.

Pour in all but a little bit of your milk and stir until JUST combined. Do not overmix.

Carefully remove the cast iron skillet from the oven and add 1 tbsp of oil to evenly coat the bottom and sides of the pan.

Use a large cookie scoop to scoop out 6 large biscuits into your oiled cast iron skillet. If desired, sprinkle the top of each biscuit with more shredded cheddar cheese.

Bake in the oven for 12-15 minutes.

About 5 minutes before finishing, melt 2 tbsp butter and combine it with garlic powder and parsley.

After removing the biscuits from the oven, immediately brush the tops with the garlic, butter, and parsley mixture.
