Ah, cake delivery. Arguably the single most stressful event of the cake-making process. Add a hot summers day into the mix and you've got one potential hot mess on your hands, and I'm not just talking about ME (the other hot mess).
So how was this insulated cake box born? Well, out of the FEAR of a cake tragedy, of course! My AC had gone out in my car and I had no other choice but to come up with a solution for delivering my cakes later that weekend. I had remembered seeing something a while back from Minette Rushing (Custom Cake Savannah Georgia) where her husband had put together a make-shift cooler for her cakes. He used insulation that you would get at the hardware store! I couldn't find her original post and I couldn't quite remember what they did, so I went to the hardware store, bought some insulation, and came up with this! After an hour drive not only did it get my cake to the event, it was STILL cold to the touch! And now this box is my cake delivery best friend forever.
And how do you confirm that you came up with something great? You and another cake friend have the exact same idea unbeknownst to each other. My fabulous dear friend Nathalie Sorensen (Lucy Cake Design and HotHands Modeling Chocolate) came up with almost the exact same idea! She had actually Periscoped it earlier in the year (which somehow I missed!) and then I put out an almost identical Facebook live tutorial months later. Small world right?! Cakers are constantly coming up against the same problems, and Nathalie and I happened to follow the same path to a solution!
Anywho, here is a how-to make an insulated cake delivery box for all your cake needs! This easy and inexpensive DIY is the perfect solution for a hot summer day or a long trip in the car. So what will you need?
Here is a Facebook LIVE on how to make your very own insulated cake box! It's pretty easy peasy! I've also added some photos below for a helpful breakdown and some additional tips!
Tape your box together on the bottom. Cut your door down one side and then horizontally, approx 1.5"-2" above the base.
When cutting your panels of foam, measure in the order illustrated in the photo below. Measure the inside top, cut your panel, and place it inside. With that top panel in place, measure your back wall and cut your foam. You need to make sure you put each corresponding panels of foam in as you go and then measure, that way your panels have room for the 1/2" width of the other panel. Keep repeating these steps in order so that you have the right size panels, and they fit together nice and tight like a puzzle.
I use Velcro to keep the panels attached to the walls so they stay in place (and don't fall on the cake, ekk terrifying!). I also re-use this box over and over again for my cake deliveries, so this makes it easy to break it down later and store flat! You can, of course, use tape loops if you'd like, but Velcro is a great re-usable solution. I also use one piece of Velcro on the back of the door to keep it open while I'm loading my cakes in and out!
In the end, it should look something like this!
To keep your cake from sliding about, there are a few ways you can go about it! Non-slip (or non-skid) mats work great to keep smaller cakes in place while delivering!
If I have a larger cake or just want to feel more secure, then I will cut a little slot from some leftover foam to fit nice and tight between my cake baseboard and the walls of my box.
This next awesome tip comes from my friend Shannon Bond (Shannon Bond Cake Design)! She and her hubby are straight-up smarty pants... brain waves working on overload kind-o people! She found these great ice packs that are not only reusable, they stay frozen for HOURS and they aren't liquid, so you don't have to worry about liquid puncturing and ruining your cake (like regular ole ice bags).
Alternatively, you can also use dry ice, as it will never turn into liquid (it evaporates as a gas)! Caution, dry ice can burn your skin, so always use gloves and tongs when handling it!
So there it is! Hope this can be a new-found essential tool for all your stressful cake deliveries!

Hi , great idea! My only question is if I did use ice packs, where would you put those so they wouldn’t touch the cake?
If they are the ice packs, we'll put them in zip lock bags and then tape them to the sides of the box...
Great idea but I was wondering where exactly do you put the ice? Below the mat? Thanks!
Hey Tess! If they are the ice packs, we'll put them in zip lock bags and then tape them to the sides of the box...
When you say “tape the ice packs on the sides of the box”, do you mean inside or outside of the box? I just so afraid that they will be untaped and crash to the cake if being placed inside.
Hey there! Yes, I find putting them in a zip lock and then taping it a whole lot to the walls inside the box, toward the bottom (just to help with gravity haha)
Love this!
Brilliant explanation, Thank you! I made one years ago and had forgotten how I did it. Thanks for the instructions.
I, too, was scared of the ice pack falling off the sides, so I made a "table" out of a piece of wood from Michaels, and screwed on some blocks to raise it off the ground, and placed the ice packs wrapped in a towel to absorb the condensation UNDER the wood table. Worked like a charm!
This is really amazing, I transport a 2 tiered cake with no issue 5 hours from home and everything was perfect .. I really recommend it .
Can't find these insulated foam panels anywhere in any big box store or onli e..any thoughts?
Hi Zane, we found ours at Home Depot in the insulation area. No luck there?
Thank you so much for this! I'm planning to start my cake business soon, but since I'll be doing it from home and I'm not comfortable with people coming to my home to pick up their cakes and I can't afford a store yet, I'm planning to offer delivery only. But I was so worried about how on earth I was going to safely deliver the cakes, especially in the heat of summer. And you saved me! I'm not from the US, but I doubt it's hard to find cardboard boxes and insulation panels where I live lol, so I'm definitely going to try this and make a big box so I can deliver 4 to 6 cakes at once (they'll go in their own individual boxes, so don't worry!). I'll let you know how it went!
