I'm looking for a buttercream recipe that is not too sweet. The one that I use is 1 cup Shortening, 1 cup butter, vanilla and 2 lbs. of sugar. I use this recipe for BC cakes as well as for fondant cakes (to use underneath fondant). Although, the one feedback I've repeatedly received is that the BC is overly sweet and I have to agree. I find it very sweet as well. I understand that it needs to have that quantity of sugar so that it will crust properly (for either piping or covering with fondant).
Is there a recipe out there for vanilla BC that can be used for fondant covered cakes?
