Step 1

Line a baking sheet with a silicone baking mat and set aside.

Step 2

In a large bowl, whisk together the gluten free flour, xanthan gum (if using), baking powder, sugar, garlic powder, salt, baking soda, and Old Bay Seasoning. Whisk in the parsley.

Step 3

Add the butter to the flour mixture and cut in with a pastry blender until it resembles coarse crumbs. If you're using frozen grated butter, just stir it in until it's coated with the flour.

Step 4

Stir in cheese. Once the cheese is mixed in, stir in the buttermilk and mix until all the dry ingredients are incorporated.

Step 5

Use a large scoop to portion your dough into 12 even biscuits. Drop the biscuit dough onto the prepared baking sheet and gently press down to flatten the top of the biscuits. Arrange the biscuits on the baking sheet so that they're about 1/2 an inch between the biscuits.

Step 6

Place the biscuits in the refrigerator and chill for 30 minutes before baking. Then preheat your oven to 425 degrees and let it come to temperature while the biscuits are chilling.

Step 7

Once the biscuits have chilled, brush the top of each biscuit with a little buttermilk and then bake at 425 degrees for 14-18 minutes or until baked all the way through.

Step 8

While the biscuits are baking, make the topping by stirring together the melted butter and Old Bay Seasoning.

Step 9

When the biscuits are done, brush the tops of the biscuits with the butter topping and then sprinkle the fresh parsley over the tops of the biscuits. Serve immediately or at room temperature.
