How Our Cake Jars Stay Fresh During Shipping

Shipping cake jars isn’t always easy, especially during warmer months. In fact, we pause most standard shipments in the summer because of the heat. 

While we do offer FedEx 2-day shipping at checkout for those who still want to order, most of our cake jar deliveries happen from fall through the holidays, when cooler temps make it easier to ship fresh.

Over time, we've tested and refined a packing process that works well for long-distance orders. Whether you're sending a gift or ordering a bundle for yourself, here’s exactly how we ship our cake jars to keep them safe, fresh, and ready to enjoy.

​What We Use to Ship Our Cake Jars

We don’t just toss cake jars in a box and hope for the best. Here’s what goes into every shipment:

• A sturdy shipping box
• Custom-cut insulated foam panels
• Frozen gel packs
• Bubble pouches for each jar
• Air pillows for added cushion
• Foil tape to seal it all in​​ ​

We start with a strong box, custom foam insulation, and frozen gel packs to help keep everything cool during transit.

Every jar is wrapped tightly and packed with care. Once everything’s loaded, we seal it with heavy-duty foil tape to keep cold air in and warm air out.

Why We Ship Frozen

​We freeze our cake jars before shipping. That helps keep them cool longer and gives us a buffer in case a shipment gets delayed. It’s the best way we’ve found to keep your cakes fresh without needing dry ice or a cooler.

▶ Watch Melissa Pack a Cake Jar Order

When your box arrives, your jars may be cold, partially frozen, or just slightly chilled, depending on how far it traveled. All of that is normal. Pop them in the fridge to enjoy within a few days, or stash them in the freezer for longer storage.

​Summer Shipping Note

Shipping goods in the summer can be challenging. Because cake jars are perishable and sensitive to heat, we limit shipments during hot weather unless you select 2-day shipping with FedEx at checkout. 

This helps reduce the risk of spoilage during transit. We’ll always prioritize quality over speed, especially when temperatures rise.

What to Do When Your Cake Jars Arrive

Every order comes with a sticker on the box that says: "REFRIGERATE UPON ARRIVAL."

Here’s what to do:

• Unpack your jars right away.
• Place them in the fridge if you plan to eat them within the week.
• Freeze them if you want to enjoy them later.

​They thaw beautifully, just move one from the freezer to the fridge overnight or leave it at room temperature for 20-30 minutes.

How Long Will the Cake Jars Last?

In the fridge, your cake jars will stay fresh for up to 5-7 days. In the freezer, they’ll last up to a month.
​
We don’t use any preservatives, so the freshness comes from our shipping method and your quick storage.

​What If There’s a Shipping Delay?

Delays can happen, but we’ve built our process around that. Freezing before shipment, gel packs, insulation, plus jars that can handle an extra day or two in transit.

Two jars are wrapped in bubble wrap to keep layers intact and treats protected in transit.

If your jars arrive warm, damaged, or unsealed, please email us right away with photos so we can make it right. We’re proud of how we pack, but we know not every carrier handles boxes with care.

Why the Packaging Matters

We get a lot of compliments on our packaging, not just because it looks cute (although it does), but because it keeps your cake jars protected.

• The foam insulation slows down melting.
• Bubble wrap keeps jars from bumping or cracking.
• The outer box is sturdy enough to handle rough handling

We finish each shipment with protective wrapping, extra cushion, and a clear label for how to store your jars when they arrive.

We treat every order like it’s a gift, because it usually is.

A Quick Note About the Environment

We’re always working on ways to reduce waste without sacrificing freshness. Our bubble pouches are recyclable, and we’re exploring compostable insulation options for future shipments.

Before You Order: A Few Quick Tips

• Choose a delivery date 1-2 days before your event, just in case of carrier delays.
• Sending a gift? Let us know in the order notes - we’ll leave out the receipt and include a handwritten message.
• Store jars upright. They’ll look just as pretty as when they left our kitchen.

Final Thoughts

We put a lot of care into how we ship your jars, and we’re always working to make the experience even better.
