Preheat oven to 375°F.
Place a 10–12 inch cast-iron skillet in the oven with butter. Let butter melt while the oven heats.
In a bowl, mix corn muffin mix, eggs, milk, sour cream, and cheddar just until combined.
Carefully remove the hot skillet and swirl butter to coat. Pour in batter and smooth the top.
Gently press jalapeño slices into the surface.
Bake 25–30 minutes, until golden and a toothpick inserted in the center comes out clean.
Let rest 5–10 minutes, then slice and lightly drizzle with warm hot honey before serving.
