I am new to this site and found it thank goodness by accident. I am preparing for a huge wedding cake.  It appears the box cake mixes have changed sizes as I have been reading on this site.  I always use cake mixes for my base.  Can anyone offer suggestions or should I just go to scratch?  Any help would be appreciated.  Also, if you offer a recipe can it please be one that doubles or triples easily as my bottom tier will be a 16inch round. Thanks.

ARose Levy gives you recipes in the back of the Cake Bible for large cakes like a wedding cake.

Her cakes never disappoint if scratch is the way you'd like to go.
