Once when I had leftover sweet potato pie filling, I wondered what I could do with it. Y'all know I don't like to waste food! So, I thought it would be fun to combine two of my favorite things: cornbread and sweet potato pie. The filling gets swirled into the cornbread batter for a sweet and savory mashup that everyone is sure to love.
For the sweet potato pie filling: Boil the sweet potato whole in a saucepan in enough water to cover until tender when pierced, 20 to 25 minutes. Peel and slice.
Preheat the oven to 400 degrees F. Grease a 12-inch cast-iron skillet with cooking spray.
Combine the sweet potato, sugar, butter, cream, orange juice, cinnamon, nutmeg, vanilla and egg in a food processor. Pulse until the mixture is smooth and no lumps remain. Set aside.
Make the cornbread: Combine the cornmeal, flour, sugar, baking powder and salt in a medium bowl. Whisk together the buttermilk, egg, butter and oil in a separate bowl. Add the buttermilk mixture to the flour mixture, stirring just until the dry ingredients are moistened. (The batter will be lumpy and thick.)
Pour the cornbread batter into the greased skillet. Spoon the sweet potato pie filling over the top in dollops. Use a wooden or metal skewer to create a marbling effect. (But do not mix in the sweet potato filling too much.)
Bake the cornbread until a toothpick inserted in the center comes out clean, 30 to 35 minutes. Cool on a wire rack for 7 minutes before serving.
