I made this last year for a club member who hosted a workshop on her birthday! Each "slice" has candy in it. I believe I got the template from Stampin' Up!'s collection of templates on their website.

I found the template. There are actually 3 different sized layers you can make. I did the middle one. Go to http://www.stampinup.com/us/enu/3149_8208.asp to see a picture of the full cake then click on "Download Pattern" to bring up the template. You can go to the template directly here: http://www.stampinup.com/us/documents/Piece-A-Cake.pdf. Note that you have to be a demonstrator to access these templates. If you aren't a demonstrator, pm me, and I can email you the template.
Edit: It looks like you don't actually need to be a demo to access the template (second link), but you do need to be a demo to access the picture in the first link.
What kind of glue do you use to put the boxes together? I tried permanent snail adhesive and it just doesn't hold good enough. I find boxes start coming apart after a while :(
