When making the cake, avoid using ingredients that may spoil during transport, like cream cheese frosting, custard, or fruits, just in case the cake begins to thaw.
If you order frozen foods to be delivered, these often come in insulated bags with ice packs that you can use for the cake, or they can be purchased at a grocery store or big box store. As an alternative to ice packs, consider using dry ice. Wear gloves if you’re handling dry ice, as it will burn your skin. Use a container that’s tight and fits the cake nicely so it’s doesn’t move around too much during shipping.
USPS has free 2-day shipping boxes that come in varying sizes that you can use to ship your cake in. While the box itself is free, you’ll pay a flat rate for shipping.
Place the padding on all sides of the cake to protect it.
Tape the top, bottom, and each edge of the box using packing tape. Use multiple layers of the tape to create a secure seal.
Make sure the address and shipping barcode are clearly visible on the box.
If you have a sticker that says “Fragile,” this would work as well.
If you choose a flat-rate box from USPS, your cake will arrive in 2 business days. Fast shipping options often include overnight shipping, next-day shipping, or two-day shipping.
If you ship it out on a Wednesday, get to the post office early in the morning to make sure it’s sent out that day.
Consider giving the tracking number to whomever you’re shipping the cake to so they can track it as well.
