Add a 12" cast iron skillet to the oven, and set it to preheat at 400 degrees.
In a large skillet over medium heat, melt 7 tablespoons of butter.
Add the cream cheese & half the cheddar, stirring until the mixture's smooth.
Remove the skillet from heat. Whisk in the flour, cornmeal, baking powder, salt, & cinnamon- whisking just until combined. Don't over mix.
Add the milk & pumpkin, mixing again just until combined.
Remove the skillet from the oven, add the remaining tablespoon of butter and tilt the skillet so that as it melts it swirls around & coats the bottom and side of the skillet.
Pour the batter into the preheated skillet, top it with the remaining cheese, and bake for 20-25 minutes- or until a toothpick inserted in the center comes out clean.
Remove the skillet from the oven and let it rest for 3-5 minutes before slicing and serving.
Serve as is, or you can top each slice with a pat of butter and/or a drizzle of honey.
