Detailed Instructions:

I used 2 12-oz bags of frozen peach slices. I sprayed my 8 x 11.5" pan with Pam. Put the frozen peaches in the sprayed pan. Sprinkled about 1/2 the box of Sugar Free Yellow Cake Mix on top of the slices. Poured about 1/2 the can of Diet Mountain Dew over the cake mix - pouring slowly as it tends to foam up. There will still be a few lumps that are not covered and stay kind of dry. That is OK. Bake at 350˚ for about an hour. I kept checking it about every 15 min or so. I wanted to make sure the center started bubbling. Peaches are very watery, so I wanted to bake it long enough to start thickening the peaches. It may take you a bit longer or shorter. The top does not get real brown, so you can bake it as long as it takes. When I made the Blueberry version, it did not take as long to bake.
