In a large bowl, combine flour, sugar, baking powder, garlic and salt. Add in the buttermilk, butter and cheddar and gently mix just until dough comes together.
Drop spoonfuls of dough on baking sheet, around ¼ each (making 12 biscuits) and 2 inches apart. Bake until lightly golden, about 10-15 minutes.
In a small bowl, combine melted butter and parsley. When the biscuits come out of the oven, brush on the melted butter and serve.
