Preheat oven to 400 degrees. Like a baking sheet with parchment paper and set aside. 

In a bowl, mix flour, cheddar cheese, baking powder, garlic powder, salt, and parsley together.

In a another bowl, whisk milk, egg, and butter together. Pour into dry ingredients.

Mix wet and dry until a sticky dough forms, being careful not to overmix it. If the dough is dry, add a splash of milk. 

Spoon dough into 8-10 mounds on prepared baking sheet, about 2 inches apart. 

Bake for 400 degrees for 12-14 minutes. Meanwhile, combine ingredients for topping. 

Brush each biscuit with topping and return to oven for an additional 5 minutes. Makes 8-10 biscuits.
