These are great for treats, and for making “fake cakes” and carving 3D sculptures you can cover in fondant or gumpaste. Plus it is easy and cheap!

first time ive tried making my own krispie treats and i have to say i'm impressed with this recipe so were the kids ha ha Thankyou will definately use it again!

buttercreamdreams Says... 26 Oct 2009 , 7:24pm

do you put these in the fridge to cool or just keep them on the counter top for an hour or so? When it is safe to use the RKT?

shads Says... 27 Oct 2009 , 4:37am

I have never tried using RKT before but am very interested. Would also like to know the answer about how long to leave it before trying to mould it. Does it all just stick together? Do you need damp hands? Sorry for all the q's - any help would be appreciated!!

Miffy Says... 29 Oct 2009 , 5:27am

Love this recipe!! Have never used RKT before so was a bit nervous....worked perfectly. Carved a car and had no problems at all. In answer to the above questions, I pushed it into a tin very firmly, then popped it into the fridge until it was nice and firm. Then I just cut the size I needed and started carving. I didn't need damp hands. Love it!! (Am about to use it again)

artscallion Says... 8 Jan 2010 , 1:07pm

I'm confused. My box of Rice Krispies holds about 10 cups and it only weighs 8 oz. How can 4 cups weigh 1 pound, as your recipe indicates? Am I reading this incorrectly?

cawolina Says... 5 Feb 2010 , 3:03pm

This sounds sooo much easier than i thought it would be! Thank you! :D Im gonna use this for a cake shaped like Hello kitty (I need it for the ears :P) :D

sweetiesbykim Says... 5 Feb 2010 , 5:49pm

Weight and volume are labeled with the same words for some reason (pounds and ounces), but are not the same, like on a cereal box. The 1 pound of rice krispies is not equal to 16oz or 2 cups, like it says on a pyrex measuring cup. The 1 pound refers to the weight on the scale of 4 cups of Rice Krispies, not the volume. Think of a 1 cup pyrex measuring cup which is marked 8 ounces (volume). One cup/8oz of feathers would not weigh the same as 1 cup/8oz of rocks! Most bakers measure in measuring cups, but others, like me, like to weigh my ingredients on a scale. HTH :)

mrsmurphy Says... 6 Feb 2010 , 7:21am

With all of that butter did the treats soften or fall apart at all after coming back to room temp?

momvarden Says... 10 Feb 2010 , 10:12pm

ok, i made these according to the recipe, but used all of the notes below from your comments to make sure i was paying attention to all of the details. One of the things i have always done when making this rkt's is to use extra grease (butter/marg.) on my hands or used a piece of wax paper to push them down firm. By far the best way was to wet your hands and shake off the excess(like you do when you use one of those air hand dryers). that was the first thing. I measure dry ingredients in a non liquid measuring cup. when i find an amount that works i weight it, instead of measuring it out (it makes it much easier) i used a food scale for dieting for a long time ( i just had to manually zero it every time i used it) I now use 7 oz( i think its 6 or 7 cups i will double check that) of rk, i use marg. instead of butter($), and i use any size marshmallow and melt them in the microwave. i line the pan with a piece of wax paper. Pheww that was a lot to say.!!!! i hope it helps.

this recipe worked out great. i made a trunk lid from it and this weekend i will be doing a plane...thanks everyone!

AngieD300 Says... 16 Mar 2010 , 4:22pm

I have a question about the RKT...if i want to cover with fondant, do i coat the RKT with buttercream or something to help the fondant stick? thanks for any help!!

momvarden Says... 18 Mar 2010 , 5:01pm

ps it was 7cups of rk, when using a dry measure cup.

cakes47 Says... 20 Mar 2010 , 9:31am

I too would like to know if the RK need any kind of covering before putting on the fondant. TIA :)

bobhope Says... 22 Mar 2010 , 8:08am

you melt the butter..but what if you use veg oil?do you heat it first?..thanks

CatonaLimb Says... 22 Mar 2010 , 5:21pm

I would also like to know if the rk needs a covering before fondant -- how do you keep it from being all bumpy? Just really thick fondant?

alewop Says... 25 Mar 2010 , 8:55pm

I've actually put my RKT in the food processor on "pulse" to not make it so bumpy. Just make sure to measure out the amount you need before you blend it up. Also, I add a "crumb coat" on my sculptures for two reasons a) to fill in the grooves some what and b) to help the fondant stick :)

rachael_zach Says... 27 Mar 2010 , 9:09am

Hi there, I want to mold this into a spiderman 3D cake. Would i need to let it cool down first or just do it staright away?

kipsie Says... 28 Mar 2010 , 11:20am

working on a golf bag for a grooms cake every time i apply my pockets etc... it keeps falling back off afetr a couple of hours any suggestions? thanks

cubcakes Says... 16 Apr 2010 , 10:45am

For those covering RKT's with fondant....once your "piece" is carved or shaped...cover it with melted white choc (or royal icing for a showpiece) and let it set up. It's messy but this will fill in all the nooks and crannies for a smoother surface. Then use a spray bottle of water to dampen it so your fondant will adhere to it.

Miffy Says... 21 Apr 2010 , 4:10am

I just used dark chocolate ganache to cover. Let set then smoothed it. Then I sprayed it lightly with water and covered it with fondant.

Bunnyhugger Says... 8 May 2010 , 4:45am

Is there an alternative to marshmallows that works for this? I'm a vegetarian and marshmallow contains gelatine. I also live in the UK and although we can get Fluff over here, it's quite hard to come by. Thanks :)

Pamperedtammy Says... 19 May 2010 , 9:00am

I've seen it done on TV that there has been corn syrup in the recipe. Has anyone tried this or has a recipe?

marion123 Says... 2 Jun 2010 , 1:39pm

How long can I make it in advance for a design? I'm doing a lobster cake for a July 10th wedding and want to make as much as possible ahead of time... I was going to make the claws in RKT and cover in Red Fondant.. What do you think? Thank you so much!!

jennybox Says... 24 Jun 2010 , 1:07pm

So I'm still confused about the amount of Rice Krispies to use... 4 cups with a dry measuring cup? Does that equal a pound? I don't have a kitchen scale. Any help would be appreciated! Thanks!!!

artscallion Says... 4 Jul 2010 , 8:12am

Sweetiesbykim, I'm not confusing weights and volumes here. So my question still remains.

My box of cereal contains 10 cups (cups are a volume measurement, always) and that 10 cups (volume) weighs 8 ounces (weight).

The recipe says that 4 cups (volume) equal one pound. Pounds are always a weight measurement. So there can be no confusing that 1 pound is 16 ounces (weight)

So my question remains, do 10 cups of cereal weigh 8 ounces, like the cereal box says. Or do 4 cups (less than half that amount) weigh 16 ounces (twice the weight)? Both can't be correct and the difference is huge.

If I weigh out 16 ounces I get 13 cups of cereal, not 4! If I measure 4 cups of cereal out, it only weighs about 3 ounces, not a pound.

Anyone?

artscallion Says... 4 Jul 2010 , 8:15am

PS... Sweetiesbykim said... "Weight and volume are labeled with the same words for some reason (pounds and ounces)"

Ounces can be either volume or weight. But pounds cannot. Pounds are always weight.

artscallion Says... 4 Jul 2010 , 8:25am

PPS...

according to the nutrition label: http://tinyurl.com/2aoew28 one cup of cereal weighs about one ounce. So 4 cups of cereal should weigh about 4 ounces, not 16.

So, for those who are using this recipe with success, how much cereal are you using and how are you measuring it?

michelle-moffat Says... 14 Jul 2010 , 12:54am

thanks for the belnding tip rachael zach....just finished my robots legs & got a beautiful smooth finish, love this rkt it orks every time! x

michelle-moffat Says... 14 Jul 2010 , 12:57am

hi sorry just realised it was actually alewop who recommended blending! thanks again x

khgracie Says... 25 Aug 2010 , 12:33pm

Ok, this recipe is the same one found on the indide of the Rice Krispies Cereal box, by Kellog's, less 2 cups of cereal. When making treats to eat, the cereal is measured by dry cup measure. Since it is literally rice, expanded by air, to come to a full 1 lb of cereal would require a huge amount as artscallion has mentioned. Just measure 4 cups to your 16 oz of marshmallows. This should give you a nice consistency to work with. I make mine to eat as a snack with the kids with 6 cups of cereal, and they're compact, and firm. Less RK cereal would give a more malliable treat. As well, the grease used whether it be margarine or butter is really to keep the marshmallows from sticking to the bowl/pot being used to melt them. I do mine in a large dutch oven and pat down in a 9x13 pan with dampened hands. Then I scrape out the pot, and eat the leftovers!

jtonak Says... 30 Aug 2010 , 12:43pm

This was an awful recipe! I used it to make the head of a cow so it would be lighter and easy to mold. The recipe was way too heavy and even with multiple dowel rods for support it crushed my cake! It was incredibly difficult to use and completely ruined my cake. I recommend the original recipe from the rice krispie website. That recipe is light and very easy to mold, shape and carve!!

barbthecakelady Says... 3 Sep 2010 , 10:51am

If you "pulse" the RK's in the blender, do you need to use more than 4 cups? It looks like such a small amount!

lauriekailee Says... 27 Sep 2010 , 11:49am

Well, after reading all the comments above, I don't know what amount to use.

Does anyone have a recipe that worked, either just in cups, or just in ounces! When I say worked, I mean for precise molding...and has anyone ever covered it in modeling chocolate, not fondant? Does it work okay, and what if anything, do you "crumb coat" the rkt in before covering it?

dolcebaci Says... 6 Oct 2010 , 12:53pm

Am i the only peroson in the world that thinks this recipe is "too wet" I let my sheets sit out for a week and they were still to "mosit" to shape with after a week. What am I doing wrong?

lauralee422 Says... 14 Oct 2010 , 1:09pm

I used this recipe for the first time.. and it was great and fun to do. I did put the rice kripys in the food processesor first, and they came out nice and smooth. I measured out the cups of treats and blended them up. They shrunk up a bit but then i added a few more and all was well! My only concern is that the cake is due in two weeks, hopefully the sugar won't go bd or anything.. I have it wrapped in saran wrap right now. Oh and I molded it while they were still warm a little. Very fun!

tania9 Says... 25 Oct 2010 , 5:41pm

I followed it and mine keep falling apart, any suggestions as to what am I doing wrong?? Thanks

chellscakes Says... 13 Nov 2010 , 2:43pm

The recipe on the rice krispie cake site is brilliant, its in easy measures and can be moulded or carved, foolproof recipe for any modelling or moulding.

chellscakes Says... 13 Nov 2010 , 2:45pm

Hi again, the addy is www.ricekrispies.com

Duchy Says... 2 Dec 2010 , 7:24pm

1 bag of mini marshmellows weighs about 454 g... 4 cups weights approximately 227g...not even close to 1 lb.

I would just ignore the weight altogether.

4 cups marshmellows 5 cups rice krispie treats only 3 tbspn of butter or margarine.

1/4 makes it to wet.

Yet this recipe and Kellogg's recipe is still a little too wet for modelling the underside of a 3d cake...

dolcebaci Says... 19 Jan 2011 , 9:10pm

Okay dumb question...I need to take a sheet of this to a cake show (Ohio from Toronto) will this dry out like crazy? I am unable to find a sheet to buy

TishaI Says... 19 Feb 2011 , 12:34pm

So here's what i know about weight. 16oz=1 pound now if the box is say that 10cups=8oz. thats 8oz short of a pound so it takes 20 cups to equal one pound why she ever said four is just confusing i'm going to weigh it right now the i've also found out making molding RKT is that you ready need to smash to make it hold it form. and on other recipes i've sen for molding it calls for two

Kanani_kawai Says... 24 Feb 2011 , 9:28pm

so for molding do i use 4 cups or 2 cups?

Billie84 Says... 13 Mar 2011 , 2:12pm

I think you guys might be over analyzing it... It seems to me they are just saying 4 cups from a 1lb bag of rice krispies cereal. I don't think they are referring to how much your 4 cups should weigh? Just ignore the weight part if its making you think soo much. Or use another recipe. I made this recipe for my wand, I didn't have any issues.

Ekaba Says... 15 Mar 2011 , 9:55am

I tried the original treats recipe from the rice krispies box and it cut and behaved beautifully. It cooled quickly and I was able to cut out what I needed(and had fun eating the runoff! ^_^) I LOVE this recipe! Just wanted to let you all know.

monkee73 Says... 21 Mar 2011 , 5:07pm

just made these tonight....worked perfectly!!!!!!!! Thank you!!!

AENM1 Says... 25 Apr 2011 , 9:30am

#1 Do you HAVE to cover teh RKT with soemthing before applying fondant? #2 How far ahead can they be made/stored? Thanks AENM1

volleykjh10 Says... 31 May 2011 , 2:58pm

OK these are my questions: 1. how long ahead can I make the RKT mix and mold it? 2. if I cover the RKT mold with Buttercream icing and then fondant, then do I have to refrigerate it? 3. is it easier to mold if warmer or cool? I would like to make a tower for my tangled cake this weekend. Thanks for all your help.

satenig Says... 6 Jun 2011 , 7:30pm

i am going to use rkt for the first time to mold a church. how far in advance can I make this. Any suggestions on making the steeple.

BlueP Says... 10 Jun 2011 , 1:59am

urgent urgent

can someone please tell me converted measurments in grams? I am so confused please

MarenL Says... 29 Jun 2011 , 8:19am

I just made a test batch. If you lightly crush the 4 cups krispies before adding the marshmallow then you should add another cup of krispies because the crushed krispies blend in more to the marshmallow. Also, I used the regular size maarshmallows which come in a 10 oz bag. I would imagine without the extra krispies it would make a soggy mess. I'm making Bob-bomb from Super Mario as a "column" support for a cupcake stand. I have a ball form (an english christmas pudding mold) and am jamming the stuff in there. I'm then going to dip it in melted chocolate to smooth out the leftover nooks and then cover it in black MMF. I will also be making Bill the Bullet for the top using a tin can for a mold and then modeling the nose cone. I used to live in England. UK Marshmallows are pink and white, but the pink ones taste like strawberry. The rice krispie treats tasted great.

MarenL Says... 6 Jul 2011 , 12:04pm

OK, another hint. Crushing the cereal does make the mix heavier - because it's more dense. So if you are worried about weight then don't crush. Melted chocolate did fill in a lot of the gaps and I could cut the edges of the chocolate with scissors to even them out. Now I'm off to try the black fondant recipe to cover.....

Serendipity80 Says... 13 Jul 2011 , 7:27am

just made this tonight and its perfect! moulded it into a rough shape and will leave it in the fridge over night before it becomes scooby doo! Excellent reciepe thank so much!

How far in advance can I make a RKT sculptor?

angieh121650 Says... 29 Sep 2011 , 11:50am

I am going to use RKT for the first time to mold a lion. I will need to do the lion about 1 week before the party. How long can I keep the sculpted pieces and do they have to be refrigerated?
