How to Home-Can Peanut Butter


Although traditional home-canning methods like pressure canning and hot water baths are not recommended for a low-acid, high-density food like peanut butter, it is possible to whip up your own tasty peanut spread and store it safely in the refrigerator or freezer. The benefits of making your own peanut butter at home include healthier butter without chemical preservatives or high sugar content, a great fresh taste and your favorite consistency. Peanut butter can be kept in the refrigerator for a month or two, and will keep indefinitely in the freezer.

Things You'll Need

  • Raw peanuts
  • Vegetable oil
  • Salt (optional)
  • Honey (optional)
  • Food processor or blender
  • Spatula
  • Bowl
  • Plastic storage containers
  • Shell approximately 2 cups of raw peanuts.

  • Place the peanuts in a food processor or blender, and process until the peanuts begin to form clumps.

  • Scrape the sides of the processor or blender with a spatula to integrate larger peanut pieces into the butter, and continue processing until the butter is the desired consistency.

  • Add a tbsp. of oil to the butter. For the best taste, use peanut oil, or a neutral vegetable oil.

  • Transfer the butter to a bowl and stir in the oil, as it will now be thick enough to make processing difficult.

  • Add salt or honey as desired for taste.

  • Pour the peanut butter into a plastic storage container with an airtight lid. If you plan to store the peanut butter in the freezer, use a container that is designed to freeze; be sure to leave about an inch of space between the butter and the top of the container to allow for expansion.

Tips & Warnings

  • The oil may separate from the butter over time, so be sure to stir it well before using.
  • If your peanut butter is a bit stiff from the cold, try putting it in the microwave for 20 seconds to make it easier to spread.
  • Try creative flavor blends like honey-cinnamon peanut butter or garlic and herb peanut butter.
  • Experiment with other nuts, such as cashews, almonds or pecans, using the same method.
  • Peanuts and most nuts are mostly composed of fat, which will go rancid at room temperature. Be sure to preserve your homemade peanut butter by refrigerating or freezing it.
  • Although some older resources may provide instructions for canning peanut butter in a pressure canner or water bath, these methods are not considered safe for the prevention of botulism. The best form of safely home-canning peanut butter is through refrigeration and freezing.
