Hi Maggie,
Jar cakes are baked in wide-mouth canning jars for easy removal. Please note that the cakes are not 'canned' when complete and shouldn't be stored without being refrigerated or frozen.
You'll find more jar cake and jar mix recipes along with other food gift recipes in our
Merry Gifts section.
Also, a search here for: jar mix and again for jar cookies will give you a list of previous postings.
Happy Baking,
Betsy
