Hello! For those of you who do display cakes in buttercream, do you still use dowel rods to support the cakes? I have a 4 tier cake to display done in buttercream, I didn't know if the weight of the 1st two tiers would affect the bottom two tiers? Any input would be great. Thanks.
I'm assuming that you are usuing styrofoam cake dummies. You could insert one dowel rod down the center to keep them all attached if you want to, but the styrofoam is durable enough that you would not need any dowel rods for support. I do not use dowel rods when i'm doing display cakes. I hope this helps.

I just use my BC for the glue to hold the tiers together. I pick the cakes up by the top tier to move them. Holds great. (but bear in mind that my bc turns to concrete when applied to a dummy. If yours doesn't, maybe you shouldn't try picking them up by the top tier. 
)
Yes, I'm using styrofoam cake dummies. But would it push the frosting from underneath each tier?
how much icing were you planning on putting on that cake? 
Heck, I even have some of the styrofoam showing thru the icing before I place the next cake on top. Make sure you ice the top where the cake is going to show ... outside where the next tier is going to sit. Then a thin blop in the middle to act as glue.
It's not a real cake, ya know, .... doesnt' need the same amount of icing. Just enough to glue it together.
BTW, save some pennies and don't add flavoring to the icing ... it won't be eaten, either.
