When my sweet tooth _acts up_ I look for quick, easy and tasty treats. These bars certainly fit those qualifications. I made half with sugar free blackberry jam and the other half with blueberry. Now, I'm not swearing I only used 1/4 cup of each - I went for good crust coverage, you know. ;-) They baked up nicely browned in 23 minutes and are safely hidden from everyone else. I have a roll of ginger cookie dough on tap to be the crust for orange marmalade bars when I finish this stash! Thanks for sharing your great recipe!
