Combine butter ingredients in a bowl and mix well. Transfer mixture onto a sheet of plastic wrap and form into a roll. Wrap tightly and refrigerate for 3 hours. Preheat oven to 350°. Place oysters on an oven-safe plate or baking dish, making sure the oysters do not slide on the pan.

Remove butter from plastic wrap and slice into 12 even slices. Place 1 slice on top of each oyster and bake for 10 minutes or until bubbly.
