Canning pumpkin butter or mashed or pureed pumpkin is NOT recommended.
Home canning is not recommended for pumpkin butter or any mashed or pureed pumpkin or winter squash. In 1989, the USDA's Extension Service first published the Complete Guide to Home Canning that remains the basis of Extension recommendations today, found in the December 2009 revision. The only directions for canning pumpkin and winter squash are for cubed flesh. In fact, the directions for preparing the product include the statement, "Caution: Do not mash or puree."

Canning Cubed Pumpkin
Only pressure canning methods are recommended for canning cubed pumpkin. We have no properly researched directions to recommend for canning mashed or pureed pumpkin or winter squash, or pumpkin butter. To be safe, all low acid foods, including pumpkin, must be canned using tested pressure canning processes (Ensuring Safe Canned Foods). Older methods, such as boiling water canning for vegetables, oven canning and open-kettle canning, have been discredited and can be hazardous (Equipment and Methods Not Recommended from the USDA Complete Guide to Canning, 2009).
An average of 16 pounds is needed per canner load of 7 quarts; an average of 10 pounds is needed per canner load of 9 pints – an average of 2¼ pounds per quart. Pumpkins and squash should have a hard rind and stringless, mature pulp of ideal quality for cooking fresh. Small size pumpkins (sugar or pie varieties) make better products. Wash; remove seeds, cut into 1-inch-wide slices, and peel. Cut flesh into 1-inch cubes. Boil 2 minutes in water. Caution: Do not mash or puree. Fill jars with cubes and cover cooking liquid, leaving 1-inch headspace.
Adjust lids and process following the USDA recommendations: www.homefoodpreservation.com/how/can_04/pumpkin_winter_squash.html.
