Just about any pie recipe can be easily converted into jar pie. It’s really just a matter of form factor. Prepare a bunch, leave them in the freezer, thaw before use and bake at 375°F for 45 minutes. Couldn’t be simpler.

Alternate ideas: layer on multiple pie flavours, or partition them horizontally with the aid of construction paper. The photo below is cherry on the left, blueberry on the right.
