In the event you’re ever trapped with a need for pancake style cornbread but you don’t have any eggs for the Jiffy mix, you can sub mayo or Miracle Whip. The general ratio that I’ve seen is 1/4 cup of mayo/whip for each egg. However, I recommend starting with a bit less, especially of Miracle Whip. You’ll probably need to add more milk to compensate, but the cornbread will rise nicely. Watch out, it’ll also burn much more quickly. You might want to cut the heat a little from your normal settings.
