Step 1

Heat oven. Preheat oven to 425 degrees F. (If using an 8-inch cast iron skillet, place into oven before preheating. Heat skillet for at least 10 minutes.)

Step 2

Prepare the batter. Whisk together gluten-free cornmeal, flour, sugar, baking powder, salt, and baking soda in a large bowl. Add the milk, eggs, and oil. Whisk until combined. Batter should look almost smooth. A few lumps remaining is normal.

Step 3

Bake. If using a skillet, remove skillet from oven and place on a heatproof surface. Grease with nonstick cooking spray or brush generously with vegetable oil.If using an 8-inch round cake pan, grease the pan lightly with nonstick cooking spray. Pour batter into pan. Bake until set, about 15 minutes. The cornbread should spring back when touched.

Step 4

Cool and serve. Allow cornbread to cool for about five minutes before cutting into pieces.

Step 5

Store. Wrap cornbread and store on the counter overnight. Or cool thoroughly, wrap tightly, and freeze for up to two months. Allow cornbread to thaw on the counter.
