I have been reading so many helpful tips about stacking tiered cakes, but I have a question I haven't been able to find an answer for--maybe it's the same, but I don't know!!! I am amking a baby shower cake. They want the baby bum cake but also a sheet cake, so I am planning to do a 1/4 sheet cake (double layered) then I want to put the baby bum cake off to the left, but on pillars. What precautions should I take to make sure it doesn't sink or tip???

As long as you dowel it properly it will not sink. I use bubble tea straws for all my tiered cakes, so I'd use four of them under the baby part.

What kind of pillars?

If you're using the push in pillars, http://www.wilton.com/store/site/product.cfm?id=3E3119FF-475A-BAC0-56858282E1C02DE1&fid=63EB9DD6-475A-BAC0-5CC92A385169EC6C , it's super easy. Just push the pillars into the bottom cake, attach the plate and place the upper cake on the plate.

Hidden pillars,, http://www.wilton.com/store/site/product.cfm?id=3E3119F0-475A-BAC0-5772682F766C019C&fid=63EB9DA7-475A-BAC0-522158B536D3E04A ,, can be cut down to size, to be flush with the top of the cake. A plate is attached to the tops of the pillars and the cake placed on the plate.

Here's some "how to assemble" hints from the wilton site. http://www.wilton.com/cakes/tiered-cakes/ The concept is the same whether the base cake is a sheet or a 2-layer tier.

I love this website! Everyone is always so quick to help!!!! Thank you so much!!
