For the butter mixture:
Combine all of the ingredients together in a mixing bowl and reserve.
For the cheese mixture:
Mix all ingredients together in a mixing bowl and reserve.
For the oysters:
Preheat oven to 400 degrees. Place the raw shucked oysters on a sizzle plate or a baking sheet with a raised edge. Whisk the butter mix and scoop 1 ½ ounces of it on top of each oyster, then cover each oyster with the grated cheese mix.
Bake for 5-8 minutes, or until you can just start to see the cheese browning. Remove the oysters from the oven. Set the oven to broil and place the oysters under the broiler until they darken in color to a golden brown. (Be careful to keep an eye on them because they will burn fast.) Remove and enjoy.
