In an oven-safe skillet or pan, add your block of cream cheese to the middle and pour the can of chili on top.
Place on the grates of the smoker for 45 minutes, or until the cream cheese is fully melted.
Use a spoon or spatula, mix the cream cheese and chili until the mixture is fully incorporated, then sprinkle the shredded cheddar cheese over the top.
Place it back on the smoker for another 15-20 minutes until the cheese is melted.
Garnish with green onions (optional), and serve immediately alongside your favorite chips or crackers.
