In case you saying who??? Let me start off by saying that Mike McCarey is probably my favorite cake decorator/instructor. He owns Mike's Amazing Cakes in Redmond, WA and has been on several cake challenge competitions. He is especially known for his 3-D sculpted cake masterpieces. He also teaches several cake classes on Craftsy. I highly recommend his Craftsy classes.
Mike uses this buttercream as a base for all his amazing sculpted cakes so I thought I would give it a try under a simple fondant covered round cake. I didn't take into account the humidity factor where I live. In Mississippi, it is pretty humid all year round. Even though I didn't have any problems rolling out my fondant, when I started to put it on my chilled cake, the condensation-humidity factor kicked in. I could barely get the fondant attached to the cake before the condensation on the cold buttercream started to make the fondant extra sticky. I couldn't even smooth it. I had to wait for all the condensation to dry before I could touch the cake again. Unfortunately by that time, the buttercream had become soft which renders this technique useless as it relies on a hard buttercream to help make the fondant smooth.
So...my conclusion is that this would be a great buttercream for a filling and perhaps as frosting (when the weather is not too warm) but I don't think I can use it as a base for fondant due to the condensation factor. I am pretty sure that chocolate ganache is what I am going to have to use to get around the refrigeration-condensation issue.
