Add the pulled pork, BBQ sauce, frozen corn kernels, and smoked paprika to the slow cooker. Stir until the pork is evenly coated.
In a mixing bowl, combine the cornbread mix, egg, and milk. Stir until a thick batter forms.
Pour the cornbread batter over the pork mixture and spread it gently to cover the surface.
Sprinkle the shredded cheddar cheese evenly across the top of the batter.
Cover the slow cooker and cook on low until the cornbread layer is fully set and the cheese has melted into a golden topping.
