I'm making my wedding cake and the topper is a surprise for my fiancee so I want to make it when he is not around. He's away in a couple of weeks - is that too soon to make the topper out of RKT if the wedding is the end of December? (I'm not planning on it being eaten!) And if so, will it be ok just stored in a cardboard or Tupperware box?


Thanks for your help!

wow -- that's a long time -- it might be ok -- but i would suggest using a different medium that definitely would last -- especially since you don't  want to eat it --

i am not positive what to advise on the different medium -- i've never used it but there's cold porcelain -- i'd just hike around the crafts store till i found something -- or find something online to have delivered while he's gone or something --

i mean it probably would be ok but for a wedding you want it nice & right -- depends on so many variables -- what kind of finishing you put on it -- can you keep it from ants -- what's the weather -- idk -- myself i would not do a wedding topper that far in advance with a sugary edible substance --

what is it?

Not sure what your topper is going to be, but I made a topper for a baby shower cake out of fondant and Wilton modeling dough.  It was my first ever tiered cake and topper so I kind of stole the topper when I left (it was for a friends shower so it was fine) because I wanted to keep it as a memento.  Well that was a year a half ago and the topper still looks exactly the same.  It has been wrapped in cling wrap and sitting in my craft room on a random shelf.

But I am not sure how RKT will hold up over a long period of time.  The only thing I would be concerned with are the rice krispies getting moldy, but if they have been covered in chocolate/fondant/gumpaste then that may keep them from getting green and fuzzy.  The only thing I would suggest is maybe not place the topper directly on the cake (use some sort of barrier) just in case anything weird/stale is on the bottom of it.

But you could also go the non-edible material route and use clay if you want to give that a whirl.

I agree w/freckles........it might get moldy.  Cut a cake circle to size/shape to put it on so it does not touch the cake.  I don't think there will be a problem but don't take a chance :)

yeah i've kept cake sculptures not even rkt but cake and they looked great & didn't mold for months & months -- after the fact --  but for a wedding  -- and this is just me -- i would freak out to do it this far in advance out of edibles -- three months is a looong time -- i am super controlling regarding weddings and wedding cakes -- probably would be fine but i would not risk it

80% of the decorating  I do is make models, many of them with a Rice Krispy Treats base.  One of the first pieces I ever did - a big turkey, if you care to look in my gallery - is now close to four years old and it still looks exactly the same.  The RKT's are completely sealed by modeling chocolate and there is no mold, no odor, no change.  It has been stored on the counter at room temp, lightly covered to prevent dust.  I recently cut into another piece that was about three years old and, honestly, the RKT's looked as though they could have been eaten - which I, of course, didn't do.

Long story short, yes you can very safely make your topper now.  Just make sure it is kept no warmer than 75 degrees and covered to protect it from dust.  Do not seal it in an airtight container, like Tupperware.   I always place my models on a base of some kind so all you have to do is set it on top of the cake.  Just be sure to put wax or parchment paper between the cake and the topper.

If you are still concerned, use styrofoam instead of RKT's.  I like to use the florist oasis because it carves much easier.

You should be more than fine to keep it indefinitely assuming you do not add butter to the RKT.  The fat and milk of butter can go rancid and the water content of it would invite mold.  Just using marshmallows and rice krispies will make it firm up nicely with no moisture for mold or bacteria to grow on.  As others have said, RKTs will keep forever nearly.

i don't make rkt without butter and vanilla blush and i use less cereal than the recipe calls for so it binds especially well

What I am using RKT's for the base of a sculpture, I do not use the butter.  It will not be eaten anyway.  I put the cereal in the food processer and break it down to about 1/3 its original size, which also makes for a much more firm and sturdy mixture.  It is a lot smoother, too.

We eat Rice Krispy Treats all the time, made in a pan and sliced like brownies.  The sculptures using RKT's as the base are never eaten.

Same.  I honestly view RKT sculptures as items that are technically edible but are primarily there for decor purposes.

I use foam for inedible -- I have the foam cutters & stuff -- we are rkt-a-holics blush

sometimes I think I should be a sculptor -- or something -- I love carving that foam

Better you than me, Kate!  I HATE carving styrofoam!  Of course, I am using a serrated knife only and it doesn't work very well.  When I use foam, I use florist's oasis because it is so easy to carve.

I have never seen them, Kate.  I may check them out......or, being lazy, I may just stick with my oasis.

WOW!  I had no idea you could sculpt styrofoam like that!  I've totally changed my mind.  The foam sculpting tools have just replaced an airbrush on my wish list!
