First, preheat the smoker to 180°F with the lid closed for 15 minutes and fill the auger with your preferred flavor of pellets, see my suggestions below.
While the Smoker is preheating, shuck your ears of corn, and try to remove all the silk.
Place corn in a large stock pot and pour the water until the corn is covered. Let the corn soak as you make the butter.
Crush the garlic and slice the 2 sticks of butter in half and place both ingredients in a saucepan before placing the saucepan into the smoker.
Smoke the butter for 30 minutes. Remove from the smoker and bring inside.
Increase the smoker's temperature to 225°F as you get the corn ready.
Remove the corn from the pot and put it onto a baking sheet.
Slather each ear of corn with your smoked butter.
Place corn directly onto the grill grates of the smoker and smoke for 25 minutes.
Using tongs, flip the corn over and brush with smoked butter, and smoke for 20 more minutes.
Remove smoked corn from the smoker and place it onto a baking sheet. Pour the remaining smoked butter over the corn.
Sprinkle parmesan cheese over the corn and a pinch of salt, paprika, and parsley flakes, if desired before serving and enjoying.
