Preheat oven to 350 F. Spray an 8-inch or 9-inch square pan with cooking spray.
In a large bowl, add egg and milk and whisk together with a fork to combine. Add creamed corn and stir to combine.
Add the cornbread mix, using a spatula to combine with wet ingredients.
Scrape cornbread mixture into the prepared pan and place in the preheated oven. Cook cornbread until a toothpick inserted in the center comes out clean, about 25 to 30 minutes. Let cool a bit.
In a small bowl, add softened butter and honey and stir to combine. Cut cornbread into pieces, and slather honey butter onto the warm cornbread.
