Can you place an edible frosting sheet on top of this frosting? I've only used buttercream and cream cheese frosting when using a frosting sheet. Also, can you store a cake with this icing overnight in the refridgerator and then leave out the next day for approximately 8 hours before serving? I'm making the cake and decorating it the night before taking it to work. Thanks for your input! Hi Pamela, Unfortunately, I'd have to say no on both counts. This frosting is very fluffy, but also sticky like marshmallow and I think you'd have a hard time getting it flat for the sheet. Also, if you didn't get the sheet on just right the first try, it will stick too much to pick up and reposition. This frosting will be just fine left out, well covered, overnight. Putting in the fridge will introduce moisture, which may cause running. Hope this helps. ~ MaryJane
