Topic Title: Lego Cake Created On Wednesday May 28, 2008 4:56 PM

I am planning to do a birthday cake that looks like it has been done in Legos. I've done a search on google and haven't really seen anything that I am impressed with. So I went on the Lego website and saw that they have Lego icecube trays. So what I am thinking about doing is this. Use the icetray molds as templates for the fondant with different colors.
My question is this: do I need to wait to make the Lego molds after I have the cake iced, or could I make the Lego molds ahead of time and keep them in a ziploc bag? Also, if I could make the Lego molds ahead of time, could I place the Lego molds together to form the side and glue them together with water or vanilla, and then cover them up with plastic until I place it on the cake?
After I have the cake covered with the fondant Lego molds, I plan to put Lego Star Wars figures on top of the cake, knock out two themes at the same time. Any feedback would be greatly appreciated.
Definitely have the legos made ahead of time-- if you can help it, about a week or so. If for no other reason, doing so will cut down on your stress when crunch-time comes!
Also, If you're not concerned about the edibil-ity of the legos, you might consider molding them out of gum paste, which is generally not edible but dries much more solid and harder than fondant. Wilton makes a ready-made gum paste that can be easily tinted, and would work perfectly.
I'm actually now in the process of building a casino-themed cake and I molded little dice out of gum paste; I bring this up because the shape and thickness of the dice is similar to what you'll get from molding out of a tray. They took about 3 days to harden sufficiently. Additionally, whether you choose to work with gum paste or fondant, It's better that you store them uncovered (but in a safe place--perhaps in a cabinet rarely used or on top of the fridge) to allow them to dry properly. If stored in a ziploc, they're technically air-tight and won't dry.
