Preheat your oven to 400 F degrees.
Take your 12 inch cast iron skillet and spray it with cooking spray, and coat lightly with cornmeal to prevent the cornbread from sticking.
In a large mixing bowl, combine your dry ingredients (cornmeal, flour, baking powder and salt) and mix until combined.
Add in grated cheese and diced jalapenos. Mix until there is an even coat on the cheese and jalapenos.
In a separate mixing bowl, whisk together the buttermilk, eggs, honey and butter.
Mix the liquid mixture with the dry mixture. Mix until combined. Pour into the cast iron skillet. Top with extra jalapenos and cheese if desired.
Bake for 25 minutes or until a toothpick can be stuck in the center and come out clean.
Top with butter, serve and enjoy!
