Preheat Your Oven:
Preheat your oven to 425°F (220°C). Line a baking sheet with parchment paper.
Mix Dry Ingredients:
In a large bowl, whisk together the flour, baking powder, garlic powder, and salt.
Cut in Butter:
Using a pastry cutter or fork, cut the cold butter into the dry ingredients until the mixture resembles coarse crumbs.
Add Cheese and Milk:
Stir in the Parmesan cheese. Gradually add the milk, mixing until the dough just comes together. If the dough is too dry, add a tablespoon of milk at a time until it’s workable.
Shape the Biscuits:
Turn the dough onto a floured surface and gently knead it a few times.
Roll or pat the dough to about 1-inch thickness. Use a biscuit cutter or a glass to cut out rounds, or drop spoonfuls of dough onto the baking sheet for a rustic look.
Bake:
Place the biscuits on the prepared baking sheet. Bake for 12-15 minutes or until golden brown.
Make the Garlic Butter Topping:
While the biscuits bake, melt the butter and stir in the garlic powder and parsley.
Brush and Serve:
Remove the biscuits from the oven and brush them with the garlic butter topping while still warm.
Serve immediately and enjoy!
