Preheat the oven to 375 degrees F. Add 1 tablespoon coconut oil to an 8-inch cast-iron skillet. Put the skillet in the oven and allow to heat until very hot, 6 to 8 minutes.
Combine the cornmeal, flour, baking powder and salt in a large bowl with a whisk. In a medium bowl, combine the almond milk, applesauce, sorghum syrup, egg and the remaining 2 tablespoons coconut oil. Make a well in the center of the dry ingredients and pour in the wet ingredients. Fold to combine.
Carefully remove the hot cast-iron skillet from the oven and pour in the batter. Return the skillet to the oven and bake until the cornbread is golden with a crisp crust, about 25 minutes.
