Preheat the grill to 425°F. Place the cast-iron skillet directly on the grates. Let it heat up for about 10 minutes while you mix the batter.
Step 2: Making the Cornbread Dough
Whisk together the dry ingredients in a large mixing bowl: flour, cornmeal, baking powder, baking soda, and salt.
Whisk the milk, eggs, yogurt or sour cream, honey, and melted butter in a separate smaller bowl. Then add this to the large bowl and mix everything well until it’s mostly smooth.
Step 3: Cooking
Put some butter in the cast-iron pan. Then, pour the batter directly into the hot cast-iron pan. Move the pan to indirect heat and turn the grill down to 400°F.
Close the smoker and let it cook for 13-18 minutes, depending on how moist you like the bread. Step 4: Final Touches
Cool for at least 10 minutes. Garnish with fresh thyme and serve with chili beans or hot with butter!
