I suggest that you try SugarShack's buttercream recipe, which you can find on this site. Everyone who tries my cakes with this buttercream says, "This is really good. It isn't too sweet." HTH
I use salt water instead of regular water for my buttercream, and I use the Wilton recipe. Everyone loves it.....says it's not too sweet, perfect!
Just add salt to warm water and voila.....
It's a matter of finding one that your customers like and is workable for you.....try Swiss or Italian meringue buttercream, or the Whimsical Bakehouse buttercream recipe. These recipes should be available in the Recipes section on this site. Or, as suggested above, you can make standard American buttercream less sweet by using salt, and also by subbing a small amount of the powder sugar with flour or cornstarch (1/2 cup for every 2 lbs of powder sugar).
