Step 1

Preheat oven to 425 degrees. Place cast iron skillet in oven while it preheats.I used an 11 inch.* See notes.

Step 2

Whisk together ground flax seed and water in a small bowl. Set aside to thicken and create a flax egg.

Step 3

Add apple cider vinegar to milk and set aside for about 5 minutes.

Step 4

In a large bowl add cornmeal, flour if using, baking powder, salt, and combine thoroughly. Add applesauce, milk mixture, and flax egg to dry ingredients. Mix just to combine.

Step 5

Remove skillet from oven and add a dab of oil or cooking spray to coat the bottom. Pour cornbread batter into skillet and bake for about 20 minutes until edges pull away from skillet and a toothpick inserted comes out clean.
