Step 1: Roast the Sweet Potato
Preheat Oven to 400°F (200°C): Pierce a large sweet potato with a fork, place it on a baking sheet, and roast until tender, about 45-60 minutes.
Mash the Sweet Potato: Let it cool, then remove the skin and mash in a bowl. Measure out 1 cup for the cornbread.
Step 2: Prepare the Cornbread Batter
Reduce Oven Temperature: Lower the oven to 375°F (190°C).
Mix Dry Ingredients: In a large bowl, whisk together cornmeal, flour, baking powder, baking soda, and salt.
Mix Wet Ingredients: In another bowl, combine mashed sweet potato, melted butter, honey, eggs, and buttermilk. Whisk until smooth.
