So I am making a Star Wars Lego cake for my nephew's birthday, and I wanted to put a few Lego pieces on and around the cake.

I was thinking of using RKTs for the legos, instead of using a solid chunk of fondant/gumpaste. Which do you think would be better? They would probably be about 1x2x4 inch rectangles or 1x2x2 inch squares.

If RKTs are better, can I just buy the premade individual treats? I don't want to make more than I would use for the cake, because my husband and I don't like them.

Thanks for the help!

yes, can buy premade -- esp. in this case, why reinvent the wheel?

and yes, the individual RKT would be a good idea (heck - I'd eat those before I'd eat the cake!)

I think RKT would be much more hassle than just making them from fondant. First of all, you'll have to make them TINY because the addition of the fondant covering will make them quite a bit bigger. Plus, you have the lumpy bumpies to deal with.

If you have a long sharp, straight edge blade, cutting rectangles is easy. I like to use a clay cutting blade. You just press it down thru the fondant and it makes a super clean cut with sharp corners.

Well, I made them last night out of fondant/gumpaste, and they turned out really nice. I'll post a pic later of the final cake.

The finished cake is in my photos! I think DianeLM was correct in fondant being easier to make them smooth.
