Butter is a wonderfully delicious and versatile food. It has a high fat content which is crucial to thriving during a survival situation. I generally recommend people buy freeze dried butter powder because it lasts the longest. However, you can still dehydrate butter yourself if you wish.
Dehydrated butter can be combined with all kinds of dry ingredients to make baked goods.
In addition to butter, many dehydrated and freeze dried foods are suitable for long term storage. You can make or purchase dehydrated peanut butter powder, powdered milk, dehydrated butter milk, and many others. Rice and pasta are excellent to store long term along with butter and other foods.

If you’re interesting in long term storage of butter (or alternatives) or adding butter to your emergency food supply, you will want to dehydrate butter.
Why dehydrate butter?

When it comes to long term storage of nearly all foods, one of the primary concerns is moisture. Foods that contain moisture are more prone to spoiling and generally speaking they do not have as long of a shelf life. This is why many canned foods are not as good for long term storage as dry foods. For information on the best canned foods for survival check out our post.
If you remove moisture from butter it will extend the shelf life.
How to dehydrate butter using a home dehydrator

The simplest and likely most accessible way of dehydrating butter is by using a consumer-grade food dehydrator.
Start by making sure your butter has been refrigerated for a while to harden. This will make cutting the sticks of butter much easier. It will also prevent the butter from melting while working with it.
Cut your sticks of butter into thin pieces about 1/4 inch thick. Place the pieces of butter in an open container, plate, or the parchment paper.
Put the butter in the freezer uncovered for at least 24 hours. This will kickstart the drying process. You can leave it in the freezer to let it dry even further.
After at least 24 hours in the freezer you will notice your butter should start to look dry and cracked. This is a good sign.
Place the pieces on parchment or wax paper. Ensure the pieces of paper will fit within your dehydrator while still allowing airflow.
Place the butter into your dehydrator. And turn it on. The cooler you can keep the butter the better. If you are able to control the temperature, keep it low or put your dehydrator in a cool place while dehydrating butter.
The dehydration process will take at least 24 hours. Check on it periodically, when it looks dry and cracked that is a good sign the butter is fully dehydrated.
Keep in mind, the butter will not be completely dry because it is an oil. You can still spread the butter. It will just be devoid of nearly all moisture.
Freeze drying butter

One of the best preservation methods for butter is freeze drying. The process is essentially identical to using a standard dehydrator.
The end result will be a butter powder. The powdered butter can then be stored much longer than any other form of butter.
The biggest downside of making freeze dried butter is the high cost of most freeze drying machines. Typically these machines can cost thousands of dollars.
A good alternative is to simply buy bulk quantities of freeze dried butter if you don’t want to spend the money on a freeze drying machine.
How to store butter long term

One of the most generally accepted methods of long term food storage is through the use of vacuum sealed mylar bags with an oxygen absorber.
First dehydrate your butter. Freeze drying is best but typical dehydrated butter is fine too.
Place the dehydrated butter in a solid container like a jar. Place this in your mylar bags along with an oxygen absorber.
Vacuum seal the bags and place them in a food grade bucket or other airtight container.
This process is the same if you’re dealing with freeze dried butter powder.
How long will dehydrated butter last

Regular dehydrated butter can last up to 5 years with proper storage. This is assuming you were able to dry the butter very well.
Because dehydrated butter is a fat, it can go rancid regardless of how well it has been dried. For this reason, it is best to rotate your stocks of butter over the years to ensure you stockpile does go rancid.
How long will dehydrated butter powder last?

Mechanically separated butter powder has the longest shelf life of any butter product. You can expect it to last 20-30 years with proper storage.
This is the best type of butter suitable for super long term storage.
How to make homemade butter

There is nothing better than fresh butter. Homemade butter not only tastes amazing but it’s incredibly satisfying and easy to make.
Since you already know how to store it long term lets take a look at how you can make your own butter.
To make butter do the following:
You can use a hand whisk or any electric mixer.
Refrigerate a large mixing bowl. This will help keep the cream cool while mixing it and make the butter form much more quickly.
Fill your chilled bowl with heavy whipping cream and begin whisking.
As you whisk you will notice the cream start to thicken.
Continue whisking until the cream starts to get airy and will hold it’s shape.
When the cream will hold cold hard peaks you are at the whipped cream stage.
Keep whisking and the butter fat will start to separate and you will see liquid form at the bottom of the bowl.
Continue to whisk for several more minutes. Then strain the butter through cheese cloth to separate the butter from the liquid.
Roll the remaining butter into the shape of your choice and then wrap with wax paper.
Refrigerate and you now have fresh butter!
Types of butter
There are a few common forms of butter beyond regular butter. All can be dehydrated for long term storage.

Ghee – Excellent for cooking. This is a form of clarified butter in which the milk protein has been removed. It is made by melting the butter until the milk solids sink to the bottom of the melted butter. The liquid is then strained.
Clarified butter – Similar to ghee, this is butter that has had the milk solids separated from the butter fat. It is made by melting the butter then skimming out milk particles.
Whipped butter – This is real butter that has been whipped with a whisk or mixer to add air to it. The process makes the butter softer and easier to spread.
Honey butter – This is butter mixed with honey. It combined the rich flavors of butter with the delicious sweet flavor of honey.
Butter substitues
I love butter and like having some included in my emergency prepper stockpile. There are many other foods which can be used in place of butter if needed.
Cocoa butter – This is an edible fat from the cocoa plant. It has a cocoa flavor and can be great for cooking and skincare products.

Shea Butter – Typically used for skincare. It can be used for cooking if it is grade A. Does not go rancid.
Coconut Oil – This oil has a mild coconut flavor and makes a great butter substitute. Cold pressed unfiltered coconut oil is best.
