Anybody have any brilliant ideas on how to make a 3D spray paint can to lay on a graffiti sheet cake?

I dont know how large you want the can to be but what about 6" rounds stacked and doweled together?

Yeah, 6" is way too big. It would need to be more like 2" I think.

Do it in scale but smaller and wrap an alluminum foil cardboard insert in gumpast and decorate.

A couple of "shaved" or "trimmed" cupcakes? Two stacked on each other?

I've learned you can make just about anything with rice krispy treats, if you use the store bought ones Little Debbies are good and they can be molded easily into just about any shape. I just used them for a Mickey Mouse Club House and was really pleased with the way it turned out. Im sure they'll work for a spray can. Good Luck

If the can doesn't have to be cake, I would make RKT and cover it with fondant. like the Tiki on top of one of the cakes in my pics.

Oh yeah the rkt idea! That is just another treat on the cake. The trick is to form a really good cylinder and get it nice and smooth becore covering with fondant or modeling chocolate. After the cylinder has sett up is more firm you can roll it along until the outter cripsies get crushed and smoothed out a little better.

What about a stack of cupcakes? Bake them without the wrapper, level them off and stack. That should be about the right size.

Yeah, 6" is way too big. It would need to be more like 2" I think.

Could you bake the cake in an aluminum can? Like the tall ones that baked beans come in?

If you have any Pampered Chef bread baking tubes, that would work for making cake or for forming the RKT.

You can also put plastic wrap in a glass and push in RKT. It will come out of the shape of the glass.

Alternatively you can make a sheet cake, and use a 2 inch round cutter to make as many rounds as you need to get the right height for your spray can.
