    I haven't tried this recipe yet but just wanted to comment on it. Wouldn't it just be easier to simply use Frosted Flakes instead of going to the trouble of making the seemingly similar "Cornflake Crunch"? Also, I wondered if this might be good if made with Golden Grahams cereal instead, since the description said it was supposed to be like a Smores.

      You are literally the worst, rating something you haven’t even tried. Get out of here, no one cares about your terrible opinion.

      The cornflake crunch is amazing I promise. You will eat half of it by itself.

    These are SUPER delicious! Trying to keep things a little less sweet (and I could not find Cornflake Crunch in the store), I used plan corn flakes and it was just right.

    Family loves them!!!! My # 1 suggestion: do not overbake. The marshmallows are perfectly caramelized at 18 minutes and the cookies just get overbaked if you try for longer.

      I actually had to decrease my bake time. My oven bakes very evenly and on almost every recipe I try the bake time is dead on. For this recipe I ended up setting my timer for 14 minutes and removing most trays at 15 minutes. I'm using a standard aluminum 1/2 sheet pan just like the ones restaurants use. I made these last year for christmas and was so disappointed at how horribly they turned out. This year, I decreased the bake time and made sure the cookie dough was cold before baking. :-)

    Lastly, Use a good pan. I alternated between a standard baking sheet from the grocery store and a higher quality, thicker pure aluminum sheet and the latter turned out much better, less spreading. I could not escape the marshmallows becoming hardened sugar around the edges but other than that these turned out great!

    I have made the compost cookies in the past and they were a disaster so when I made these I made a couple changes that I think really helped. Use a high quality butter. Standard inexpensive butter has more water in it so it will spread more. I used President for these. Use Bread flour instead of All Purpose. It helps keep the structure of the cookie. Reduce the time of baking and maybe even the temperature. I baked mine at a little over 350 (oven runs cooler) and about 11-12 minutes each.

    Ok people the trick is you have to dehydrate the marshmallows or use the mini hot chocolate marshmallows. Promise you will get what you want this way.

    I'm a fairly experienced baker and was so looking forward to trying these cookies. The cornflake crunch by itself was personally the best part of the whole mess. These were a spread out and dismal disappointment for the effort required. I agree with others, the 18 minutes was way too long, think overdone florentine cookie with marshmallows and chocolate chips. Watch them closely after 10 minutes. They're overly greasy, 3+ sticks of butter for 15 cookies, seriously overkill. Would not make again.

    Just made these cookies but modified the recipe a bit. Used crushed pretzel sticks instead of corn flakes to get a saltier cookie and I don't have an electric mixer do did it all by hand. Turned out perfect. Watched the video helps. The cookie is fluffier and crisp. Almost meringue like. A little too sweet for my taste. Next time I think I'll use less sugar and add more pretzels. And best with a glass of milk!

    You have to add a little more flour, up to two cups total. I scoop them out on a sheet pan lined with a silpat and pop that into the freezer for about 30 minutes. I then put that pan in the oven. They are so delicious. They do spread, so space them pretty far apart.

    This recipe is exceptional. I consider myself an avid baker and can say these are the best cookies I have ever tasted/baked. I didn't bother with the cornflake crunch recipe (ain't nobody got time for that) and used 3 C. crushed cornflakes instead. I chilled for approx. 2 hrs and baked for 10 minutes. The 18 minutes per the recipe is extreme and would burn the cookies. They are crunchy, chewing, and buttery. They're beautiful to look at and are likely the answer to world peace.
