This easy recipe uses a Jiffy cornbread mix and lots of tender, sweet corn! Best of all, it’s made in the crockpot so the oven is free for the main dish or other sides.

  1. Love your recipes. You are my go-to, even if I already have a recipe in case yours is better…and it always is. Can I substitute corn meal for the muffin mix? I want to make this today but it is what I have on hand.

  2. I just love viewing all your receipes! If I was younger n had a family to cook for, I would make many more. Going back to cooking has helped my edema because I can control the salt level for my heart. I especially love the videos…it takes the apprehension out of making a new receipe. And, enhances my appetite.
    Thanks again, Holly n crew, for all your hard work. I’m sure you inspire young ones to learn to cook from scratch and not eat out so much.

    1. Thank you for your kind words and for following along Virginia. We’re so glad you’ve enjoyed thee recipes and videos – we’re so happy you’re here!

  3. Turned out great but took longer to cook that listed. I heavily relied on your crock pot recipes this
    year and wasn’t disappointed.4 stars

  4. Sounds lovely but is it possible to use another brand of cornbread mix?
    Surely, one larger box would be the same as two of Jiffy mix?
    I tried Jiffy twice and the result was entirely unsatisfactory both times
    I carefully followed the directions and it was dry and so bad I threw
    it out after cutting one piece
