How to Freeze Dry Ice Cream Sandwiches

Freeze dried ice cream sandwiches are one of the easiest and most fun treats to make in a home freeze dryer.

The soft ice cream becomes light and crunchy, the cookie layers turn crisp, and the finished pieces can be enjoyed without keeping them frozen. They are great for camping, road trips, packed snacks, or simply keeping a batch around when you want something different.

Even better, there is very little preparation involved.

If you have a Harvest Right freeze dryer and a box of ice cream sandwiches, you already have almost everything you need.

What You Need

You only need a few things to get started:

• Ice cream sandwiches

• Home freeze dryer

• Freeze dryer trays

• Parchment paper or tray liners, optional

• Knife or bench scraper

• Mylar bags or other moisture resistant airtight packaging

• Oxygen absorbers for longer term storage

Regular full size ice cream sandwiches work well, but mini sandwiches can also be used.

Different brands and ice cream formulas may finish slightly differently because the amount of fat, sugar, water, and air in the ice cream can vary.

How to Freeze Dry Ice Cream Sandwiches

The process is simple, but keeping the sandwiches very cold before the drying cycle begins can help them hold their shape.

1. Keep the Ice Cream Sandwiches Frozen

Leave the sandwiches in your freezer until you are ready to prepare the trays.

Ice cream softens quickly at room temperature, so it helps to work with only one or two sandwiches at a time while leaving the rest frozen.

If they begin getting noticeably soft while you are preparing them, place them back in the freezer before continuing.

2. Cut Them Into Pieces

Remove the wrappers and cut each sandwich into smaller pieces.

Four to eight pieces per sandwich usually creates an easy snack size while also exposing more surface area for freeze drying.

Try to keep the pieces reasonably similar in size. Uniform pieces tend to finish more consistently than a tray containing both tiny bites and large sections.

You can freeze dry whole ice cream sandwiches, but smaller pieces are generally easier to package, eat, and check for dryness.

3. Arrange the Pieces on Your Trays

Place the pieces in a single layer on your freeze dryer trays.

Leave a little space between them rather than packing everything tightly together.

The sandwiches may expand somewhat during processing, so avoid filling the trays all the way to the edges.

Parchment paper or reusable tray liners can make cleanup easier, especially if the ice cream softens slightly during loading.

4. Freeze the Trays Solid

For the most predictable results, place the loaded trays in a conventional freezer until the sandwiches are completely frozen solid.

Several hours will usually be enough, although leaving the trays in the freezer overnight is an easy option.

This step is especially useful with ice cream because you want the product thoroughly frozen before significant vacuum drying begins.

If you prefer to load frozen sandwiches directly into your Harvest Right, follow the operating procedure recommended for your particular machine and software version.

5. Start the Freeze Drying Cycle

Load the frozen trays into your freeze dryer and run the appropriate freeze drying cycle according to your machine's instructions.

Ice cream sandwiches contain a combination of moisture, fat, and sugar, so drying time can vary by:

• Sandwich size

• Ice cream formulation

• Thickness

• Tray load

• Room conditions

• Freeze dryer model

Rather than relying only on a specific number of hours, use the machine's completed cycle as your starting point and then physically check the food before packaging it.

6. Check That They Are Completely Dry

When the cycle finishes, remove one of the thickest pieces and break it open.

A properly freeze dried ice cream sandwich should be:

• Dry throughout

• Light

• Crisp or crunchy

• Free from cold or wet spots in the center

Pay particular attention to the middle of the ice cream layer.

If the center feels cold, soft, gummy, or moist, return the trays to the machine and add more dry time.

It is better to add additional drying time than to package food that still contains moisture.

7. Package Them Immediately

Freeze dried foods begin absorbing moisture from the surrounding air as soon as they leave the machine.

Once you have confirmed that the sandwiches are completely dry, package them promptly.

For snacks you expect to eat relatively soon, a high quality airtight container or moisture resistant bag may be sufficient.

For longer term storage, use properly sealed Mylar bags with appropriately sized oxygen absorbers.

Keep finished packages somewhere cool, dry, and away from direct sunlight.

What Do Freeze Dried Ice Cream Sandwiches Taste Like?

The texture is completely different from a frozen ice cream sandwich.

Instead of being cold and creamy, the ice cream becomes airy, dry, and crunchy. It begins dissolving as you eat it, while the chocolate cookie layers become crisp.

The result is somewhere between an ice cream sandwich and a crunchy dessert bite.

Because almost all of the water has been removed, the flavors can also seem more concentrated than they do when the sandwich is frozen.

Do They Melt?

Properly freeze dried ice cream sandwiches do not melt in the same way regular frozen ice cream does.

That makes them much easier to pack for situations where carrying a freezer or cooler would normally be inconvenient.

However, they still need to be protected from moisture, excessive heat, and physical damage.

Freeze dried pieces can be fragile, and exposure to humid air will gradually cause them to lose their crisp texture.

Tips for Better Results

Ice cream sandwiches are beginner friendly, but a few small details can make your first batch easier.

Work Quickly

Do not leave the sandwiches sitting on the counter while you prepare an entire box.

Cut a few, arrange them on the tray, and keep everything else frozen until you need it.

Start With Smaller Pieces

Whole sandwiches can be freeze dried, but smaller pieces provide more exposed surface area and make it easier to confirm that the center is dry.

They are also much easier to package as individual snacks.

Do Not Overload the Trays

More food does not always mean a better batch.

Leave enough room for the pieces to sit comfortably without stacking or pressing against one another.

Check the Thickest Piece

Always test one of the largest pieces rather than the smallest.

If the largest piece is completely dry through the center, the smaller pieces are more likely to be finished as well.

Add More Dry Time When Needed

Freeze dryer cycle times are not identical for every batch.

Food thickness, starting temperature, recipe, tray load, machine size, and environmental conditions can all affect the process.

If you are unsure whether the center is completely dry, add more dry time and check again.

Common Mistakes to Avoid

Letting the Sandwiches Melt Before Loading

Soft ice cream can become messy and may lose its shape before the freezing stage is complete.

Keep your sandwiches frozen and work quickly during preparation.

Cutting Pieces Too Large

Large pieces can work, but the center takes longer to dry and can be harder to evaluate.

Smaller portions usually provide more consistent results for a first batch.

Packaging Them While They Are Still Warm

If your machine warms the food during the final drying stage, allow the product and packaging process to follow the guidance for your machine.

The important part is preventing condensation or outside moisture from becoming trapped inside your storage bag.

Assuming the Cycle Is Finished Without Checking

A completed machine cycle does not replace a physical dryness check.

Break open one of the thickest pieces and inspect the center before sealing the entire batch.

Leaving Finished Food Exposed

Freeze dried foods readily absorb moisture from humid air.

Have your bags, containers, sealer, and oxygen absorbers ready before opening the freeze dryer so you can package the batch quickly.

Freeze Dried Ice Cream Sandwich FAQ

Can you freeze dry ice cream sandwiches?

Yes. Ice cream sandwiches can be freeze dried in a home freeze dryer. The process removes moisture from the frozen ice cream and cookie layers, creating a lightweight, crunchy snack.

Should you freeze ice cream sandwiches before freeze drying them?

Ice cream sandwiches are already sold frozen, and keeping them completely frozen during preparation helps prevent melting. For an especially easy workflow, prepare your trays and place them back into a conventional freezer until everything is frozen solid before loading the freeze dryer.

Do you need to remove the wrapper?

Removing the wrapper and cutting the sandwiches into pieces is the simplest approach for most home batches. It exposes more of the product, makes the finished food easier to check, and gives you snack sized portions that are easier to package.

Some freeze drying methods use partially opened wrappers for whole sandwiches, but always make sure any material placed in your machine is appropriate for the process and consistent with the manufacturer's instructions.

How long does it take to freeze dry ice cream sandwiches?

There is no single drying time that applies to every batch.

Freeze dryer model, sandwich size, ingredients, tray load, starting temperature, and room conditions can all influence cycle length.

Allow your freeze dryer to complete its cycle, then break open one of the thickest pieces. Add additional dry time if you find any cold, soft, gummy, or moist areas.

How do you know when freeze dried ice cream sandwiches are done?

Break open a thick piece and inspect the center.

The entire piece should be dry, lightweight, and crisp without any cold or moist spots inside the ice cream layer.

Do freeze dried ice cream sandwiches need to stay frozen?

Once properly freeze dried and packaged, they no longer need to remain in a freezer simply to maintain their freeze dried texture.

They do, however, need protection from humidity and moisture.

How should you store freeze dried ice cream sandwiches?

For longer storage, place completely dried sandwiches in properly sealed Mylar bags with oxygen absorbers and keep them somewhere cool and dry.

If you are making them for short term snacking, an airtight moisture resistant container can also work.

Can you freeze dry different flavors?

Absolutely.

Vanilla is the classic option, but chocolate, strawberry, cookies and cream, and other ice cream sandwich flavors can all be worth experimenting with.

Because recipes differ between manufacturers, expect some variation in expansion, texture, and drying time.

An Easy First Freeze Dryer Treat

Ice cream sandwiches are a great project when you want to try something fun without a complicated recipe.

Keep them frozen, cut them into manageable pieces, arrange them evenly on your trays, freeze everything solid, and let your freeze dryer do the rest.

The most important step comes at the end: check the thickest pieces carefully and make sure they are completely dry before packaging.

Once you have the process down, it is easy to experiment with different brands, flavors, sizes, and other frozen desserts.
