Preheat oven to 425°. Place 3 (5-well) or 2 (7-well) cast-iron corn stick pans in oven until hot, about 5 minutes.
In a large bowl, whisk together cornmeal, flour, 2 teaspoons thyme, 2 teaspoons oregano, sugar, chives, ¾ teaspoon salt, and pepper. In a small bowl, whisk together buttermilk, oil, egg, and minced garlic. Stir buttermilk mixture into cornmeal mixture just until combined.
Carefully remove hot pans from oven. Lightly brush wells with melted butter. Divide batter among prepared wells, about 1½ tablespoons each.
Bake until golden brown, 18 to 20 minutes. Stir garlic powder, remaining 1½ teaspoons thyme, remaining 1½ teaspoons oregano, and remaining ¼ teaspoon salt into remaining melted butter. Brush butter mixture onto hot corn sticks. Serve warm.
