Notes

The recipe for the jam will make enough for one batch of Mixed Berry Oatmeal Jam Bars. I usually have about ¼ cup of jam leftover. 
If you find your jam is runny, add a little bit of corn starch to it to help it bind together when it cooks. It will also set up nicely once you place them in the refrigerator after cooking and cooling. 
You can substitute other jams with no problem. If you don't want to invest in making your own jam, go ahead and buy your favorite instead.
