  7. Hi Gretchen
    This cake looks gorgeous and I will try it sometime.
    I noticed you used a sugar thermometer when making the candy.
    The one you used looks very nifty and I would like to know the brand name.
    Maybe it is available in South Africa.
    Many thanks.

      1. Actually, I think this is the correct link to the thermometer.


        The cake looks amazing and I’ll be trying it out this weekend. Some friends are celebrating their 30th anniversary and they are big camping enthusiasts, so of course it’s a camping themed party. Couldn’t think of a better cake for the occasion!

  8. Hi Gretchen,

    This cake looks totally amazing and I have decided to make it this weekend for a BBQ. Everyone will love it!!! I have a quick question, though. Is the chocolate that goes inside the cake part of the ganache recipe that will be used for glazing the cake? It just seems to be a different color and not from the same bowl as the ganache. Thanks Gretchen!

  9. Hi Gretchen
    Love this cake. Just baked it but it dropped in middle and came away from sides but I think if I don’t line the tin with parchment and cool upside down I will be OK tomorrow on attempt 2. No probs plenty of cake pops or push ups!!

    Could you tell me what the black ashes are made of please?

    Also my wife loves your cat and woud like to know his/her name. I think it is spoilt more than our two, they have to eat buttercream off a saucer not handfed off a fork!!!!


    1. HI Mike! Yeah this is a touchy recipe, but I like your thoughts for attempt 2
      The ashes are just toasted marshmallow, I used my blowtorch (did ya catch that part in the vid?)
      His name is Winklebean and he is spoiled to the core! LOL Love my little man! He gets whatever he wants (Id be a terrible parent)

      1. Thanks for the quick reply. If everything works out I’ll put a photo on your Facebook page.

        Take care

  10. Just made the cakes and I am not sure I got it right. How thick are the finished layers supposed to be? In your demo they look bigger than mine!

  11. Hi Gretchen:

    I am so happy I found you!!!! I lost you for a while and I was so sad…. you are a great chef and a wonderful person.

We love you and our prayers are with you for God to bless your kind heart. We are happy you are back, and wish you all the best

    Love and blessings from Australia

  12. Hi Gretchen, Another beautiful recipe (you are so talented!) Can’t wait to make it My college freshman daughter is begging me to make this cake for her birthday in a couple of weeks…she’s a smore-a-holic! (she’ll come home to visit for sure if this is on the table (LOL)! Quick question: is Graham flour interchangeable with Graham cracker crumbs…and in the same quantity?

  13. This campfire cake was a big hit for a recent Eagle Scout Court of Honor. It was the side cake (the main cake was a Boy Scout uniform shirt) but it got lots of oohs and aahs and disappeared quickly! And it was fun to make! My husband thought it tasted like tiramisu. 😀

    One question: most of the sugar fire turned grainy and opaque (it still worked fine). I took it off the stove at 300 degrees…I’m wondering if maybe I poured it a little too thick onto the silicone mat (the one from the unnamable Bakery Blog, lol), or if I should let it get just a little hotter? I have no experience with candy making. Thanks! 🙂

    1. Hey Great! Sounds like your sugar crystalized which is very common in cooking sugar (and caramel sauce!) once sugar starts boiling you cannot stir it anymore, even agitating the pan once you pour it onto the silicone mat can cause crystalization.

  14. I’m in our community colleges culinary/pastry program, I made this cake for our mid term in cake decorating class. It was really great, the instructor was impressed I made the chiffon cake and tried the sugar. The sugar did crystallize but I know what I did incorrectly. Anyway the cake was amazing. I love your videos I learn so much. I also did the Reeses peanut butter cup cake with the peanut butter swiss buttercream frosting. Thanks for all the tips and tricks!

  15. Ill make this cake but think Ill use chocolate frosting maybe your fudge or milk chocolate ganache for the filling and then cloak it all in seven minute frosting for the marshmallow component . Your opinion on the fudge or ganache ? Ill take to work for a 4th of July Potluck.

  16. I made this cake and it was a big hit. I personally find the buttercream icing a bit to sweet. Can I cut back on the sugar without changing the texture of the icing?

  17. I am so excited to try this cake!! how long should you bake it if you are making cupcakes? How many cupcakes do you think the recipe will make? my Girl Scout’s will love this!

  18. HiGretchen,

    A few years back you provided us with a delicious “Marshmallow Fluff” recipe. I wanted to do your Smores Campfire Cake, but wanted to add the Marshmallow Fluff inside. However, I was unable to find the original recipe.

    Any chance you will add the Marshmallow Fluff recipe to your blog again? Thanks 🙂

  19. Hi Gretchen,

    How are you? This cake looks so good and your are so very talented! 🙂 I’d love to make this cake in the summer for my friends. Unfortunately, one of those friends cannot have any gluten. I was wondering if there is any way for the S’mores sponge cake to be made gluten free. Please advise when you get the chance. Thank you! 🙂
