This recipe was created to accent Kernza’s unique flavors and aromas such as: honey, brown sugar, caramel, and brown butter in an easy and rustic setting. It is meant to be baked and served straight from the cast iron skillet. This will keep it warm for a very long time, and makes a fantastic centerpiece at the table! 


  1. Place Cast-Iron Skillet in oven, and preheat to 450℉. 
    **Once preheated, do not open the door for at least 5 minutes to ensure the skillet is up-to-temp. 
  2. Melt one stick of butter in pan on low heat. Once melted, turn off heat and keep warm. 
    **Do not weigh butter before it is melted! 
  3. Combine dry ingredients in a bowl: Kernza, Cornmeal, Baking Powder/Soda, Salt.

  4. In a separate bowl, Crack one egg, add sugar and honey, whisk. (A fork works fine). 
  5. Weigh/measure melted butter, and add to egg/sugar, drizzling slowly while stirring vigorously. Mix until combined and mixture is somewhat homogenous. 
  6. Add buttermilk to the wet mixture (eggs/sugars/butter), and stir to combine. 
  7. Add wet ingredients to the dry ingredients. Mix until lumps have just disappeared.

  8. Once the skillet is heated and the batter is ready, remove the skillet from the oven, and pour in the additional tbsp. of melted butter. Coat the skillet evenly, including half-way up the side. 
  9. Pour batter into the skillet, and use a spatula to quickly smooth out the surface. 
  10. Place skillet back in the oven, and set timer for 20 minutes.

  11. Once time is up, remove skillet from the oven, and insert a knife/toothpick into center to check doneness. 
    **If the cornbread needs more time, I would recommend not exceeding 5 extra minutes. 
  12. Once cornbread has finished cooking, remove the skillet from the oven, and rest at room temperature for at least 15 minutes before cutting/serving. 
    **You can rest the bread for up to 45 minutes and it will still be warm. 
  13. Enjoy as is, or serve with any combination of butter, honey, and salt.

    I’m still confused about the butter: ingredients list says 1/4 c + 1 Tb, written instructions say 1 stick.

    Hi Lois,

    That was a mistake that we hadn’t changed yet. Nice catch!

    It is supposed to be “melt one stick of butter”.

    Could you clarify step #2. It says melt at least 2 sticks of butter. I assume this is not meant to be what I think of as a stick of butter!
