Preheat your Z Grills pellet smoker to 300˚F using cherry pellets.
Put the evenly sliced peaches into a bowl. Then, add half a cup of light brown sugar, 2 tablespoons of corn starch, and a pinch of salt to your peaches, mixing thoroughly.
Scoop your peach cobbler mixture into an 8-inch cast iron pan, spreading it out evenly.
In a separate bowl, add ¾ cup of flour, 1 tablespoon of baking powder, 4 tablespoons of butter, 1 tablespoon of milk, and a pinch of salt. Mix them until a crumble consistency is achieved.
Sprinkle the crumble mixture evenly on top of the peaches. Then, top this with an extra sprinkling of cinnamon and white sugar.
Place the skillet onto the preheated smoker and close the lid. Smoke for around 40 minutes.
After 40 minutes, if the topping has browned up and the peach filling is bubbling around the edges, it’s time to remove it from the grill.
Serve and enjoy.
