I use brpboxshop boxes for many things I do (pies, cupcakes, tarts, etc) but for cakes I use the clear plastic cake domes (I get them from PlasticContainerCity.com). They show off my cakes and are better for my clients, because they keep my cakes fresher than a cardboard box.
Just my preference.

Thanks for the suggestion!

Wait, wouldn't cupcakes--which do dry out quicker than a cake--dry out in boxes, also?

I use the pink boxes exclusively. I don't have to worry about freshness because they are all baked to order and are fresh when they leave my bakery.

Okay, thanks! I have not really done cupcakes (yet) and I worry about the part of the cupcake head that might not be covered in icing/fondant. All of my cakes are usually covered, so I wondered about that!

For cupcakes I use either a 9 oz or a 12 oz lidded plastic cup - upside down.

I use various boxes from BRP. Love them all!

I too use BRP boxes (10x10x6) ALL the time!! And they work great.
Although, for cupcakes I've used the plastic container ones from different sources, mostly for convenience because of the separation between the cupcakes...
