Mess hall bistro has 2 recipes to put into jars. They have a brownie mix to make up and use for gift giving or just to have in the pantry for when ever you wish to make some brownies and then there is an easy recipe for peach pie filling. It uses the water bath canning method so it should be really easy to can some.
