Preheat the oven to 400°F. Spray or grease an 8 inch square baking dish. Set aside. In a large bowl, add cornmeal, flour, sugar, baking powder, salt, cinnamon and nutmeg. Whisk well to combine.
In a separate bowl, add the eggs, pumpkin, buttermilk, melted butter, and stir until combined. Add the cornmeal mixture to the wet batter, fold together until combined, do not over mix. Sprinkle in the chopped sage and gently fold into batter.
Pour batter into the prepared baking dish and use a spatula to even out the batter on top. Bake in the oven for 20-25 minutes. Check for doneness with a toothpick. Take the cornbread out of the oven and allow it to cool.
While that cools, grab a bowl and add the softened butter, honey, dijon, and pepper. Mix together until combined. Once the cornbread has cooled, slice and serve slightly warm with the Honey Mustard Butter on the side. Enjoy!
