Your canning jars should work fine.
If you wanted to make them small, couldn't you just use custard cups? I bake all kinds of things in them. I have collected them over the years in all shapes and sizes. I started using them for apple cake because it was just two of us at home and the reheating of the whole cake was not working, and reheating portions wasn't either. One day- inspiration struck! I pulled out the custard cups, spread them on my half sheet pan (covered with parchment), sprayed with your non-stick spray. They were perfect!
And I just watch the tops as I bake.
I think that would be a fabulous idea, Carol. Decrease the bake time for sure. Check just after 20-35 minutes. Continue baking if necessary until tester comes out clean. Elisabeth
