Does anyone have any suggestions on how to make my WASC cakes sweeter?? I think they are fine and 99% of my customers do.  But I have run across a handful of people that tell me it is not sweet enough!  I mostly use American buttercream that is super sweet.  

Maybe less vanilla?

Perhaps try brushing a simple syrup on the layers as you stack?  Honestly you can't please everyone.  Hard to imagine a cake with american buttercream that is not sweet enough.  If all else fails, perhaps you suggest they serve the cake with a side of sugar?

Wow. That is bizarre, no offense to your customers. Maybe add an extra 1/4 cup sugar to your batter. Or cut your cake layers thinner and increase the number of layers of icing. Or refer your customers to Walmart

Tell them to buy a different cake. :-D

As one other poster said....that's bizarre.     You might try adding a bit more sugar to the batter but it might make the top sticky after baking.     I sort of agree w/snowflakebunny :)   There is no way we can please *everyone all the time!*  Has this customer ordered from you before?  Did they complain about that/those order(s)?   Someone mentioned using less flavoring but I say the opposite - increase it a bit.  Same with the icing.  

She has never ordered from me before but had my cake at another party.  She was a large cake and wants me to find a sweeter cake recipe! UGH!  Can't bake a cake but wants to tell me how to do it.  Love those people!  She also won't take my advice on the size of the cake.  She is going to end up with tons of cake that may or may not be sweet enough for her because I don't have time to "experiment" with lots of recipes!

At this point, would love to!

I made the wasc cake one time and it was way too sweet for me. I can't imagine someone wanting it sweeter. To each his own!!

Perhaps another flavor?  Don't know which one was tasted but maybe another flavor would do the trick.      As for size - I remember one customer ordering a 12" round to serve 10 people!  I tried to tell them it was way too big but that's what they wanted so that's what I gave them:)

She probably has a taste for straight up cake mix which is very sweet.  Just use straight up cake mix for these too sweet is not sweet enough people.  Less work for you!

I had a wedding cake customer like this once. At the consultation I had given them a small sample....they wanted to know if I could make it sweeter!?  Um...no.  I told them that I could make slight additions to the recipe, but baking is like a science experiment and if I make too much of a change in the ingredients the cake isn't going to bake correctly.   They didn't come back....and I didn't mind at all!

Not sweet enough!!!!! Maybe they are use to cake straight out of the box with nothing added. Confetti pieces might make a cake sweeter.

MBalaska...you are absolutely correct!  There have literally been 3 of them out of the hundreds and they have been the biggest pain about everything!  Cutting the cord!

The only thing I can think of is maybe they are referring to Angel Food cake? That is super sweet. Otherwise they have killed their taste buds with substances....
