No matter what I do, I can NOT get rid of the bulge under my fondant. It's between the layers of the cakes. I have made a dam around the filling, used stiffer BC, chilled it, used thicker fondant, let the cakes have ample time to settle. Grrrrr, I don't know what else to do. It's to the point that I'm considering giving up cakes period because I can do anything else when it comes to cakes, but I cannot have a 'smooth' finish.
