I have frozen buttercream frosted cakes many times. Also smbc covered cakes. I put heavy foil in the bottom of each box, then wrap the box good with heavy foil (tape box first) The night before or the morning I want it , I take out of freezer and take the foil off. It works great for me. I usually take it in the coolest room of the house to let it thaw. Again, always works for me. hth They look great and taste great.
