So I've fairly new. I've made about 6 cakes now and each time the cake starts to bulge out after the fondant is applied I need help, but I'll start from the beginning.
My cakes are slightly not leveled once stacked, even though I use a cake leveler from Wilton also I pipe on the BC so it can be totally even. Then they are straight up or down, I'm not sure why since I only have 1 of each pan size so if I want a 2 layer I wash and reuse the same pan and once my cakes are stacked with BC the cakes most of the time do not align. I crumb coat which seems to be the easiest part because I can just add BC to make my cakes look all even everywhere top, bottom, sides. I then add another coat of thin BC then I set it in the freezer for about 10-20 minutes then I apply fondant. Everything is fine and then a couple hours later there are bulges and BC is spilling out of the cake. I need help pretty please. I've been getting asked to do more cakes and these errors makes me not want to even bake because I put a ton of stress on myself to have everything perfect
