Preheat your oven to 400°F (200°C).
Cook and mash your sweet potato until smooth.
In a large mixing bowl, combine the cornmeal, all-purpose flour, baking powder, salt, cinnamon, and nutmeg.
In another bowl, whisk together the mashed sweet potato, honey, melted butter, milk, and eggs until smooth.
Pour the wet ingredients into the dry ingredients and stir until just combined.
Pour the batter into a greased 9x9-inch baking dish and bake for 25-30 minutes.
Let the cornbread cool for about 10 minutes before slicing and serving.
