FOR BISCUITS: Combine flour, sugar, baking powder, salt, and garlic powder in a bowl. Whisk together. Using a pastry blender, cut butter into fine crumbs.
Add the shredded cheddar and stir. Add the buttermilk and mix until dough comes together in a ball and everything is wet.
Use a large spoon to drop balls of biscuit dough onto a parchment lined baking sheet.
Bake at 400 degrees Fahrenheit for 15 to 20 minutes or until lightly brown on top.
FOR BUTTER TOPPING: Melt butter in the microwave. Add the garlic powder, salt, and parsley. Mix and brush over the tops of the baked biscuits. Enjoy warm.
