June 14, 2026 update. Cornbread is coming out a bit underdone so I increased the bake time from 20 minutes to 23 minutes. Try this out and report back.
Took my favorite cornbread recipe, courtesy of Melissa Clark, and made a small batch in my little cast iron skillet. The scaled-down version produced four moderately-sized slices of cornbread.
For the small batch bake, I used 1/3 the original recipe quantities:
I baked it in a 6 inch cast iron skillet at 350 for 23 minutes.
Came out great!
