Preheat the oven to 400° F. In a large mixing bowl, combine the flour, shredded cheddar cheese, baking powder, salt, and garlic powder.
In a large 2 cup glass measure, using a hand whisk, mix together the milk and egg. Add the butter and the egg mixture to the flour mixture stirring until just combined. There will still be flecks of flour.
Using a ¼ cup measuring scoop or a large tablespoon, drop the biscuit dough onto a parchment lined rimless baking sheet. Bake for 12 minutes, or until the biscuit is lightly golden browned and the dough is cooked through.
Mix together the melted butter, garlic, and parsley. Brush over top of the baked cheddar biscuits to coat. Enjoy while still warm.
