In a large bowl, whisk together cornmeal, flour, baking powder, and salt. Stir in the melted butter, buttermilk, egg, and honey. Mix in diced bacon, shredded cheddar, and minced jalapeño. Using a pot holder, remove hot skillet from the oven. Pour cornbread batter into center of skillet, allowing melted bacon grease to spread to the edges. Smooth the top and bake for 20 minutes, or until surface is golden brown and a toothpick inserted in center comes out clean. Cool skillet for 5 minutes before slicing and serving cornbread warm.
