We picked a lot of blackberries last year and froze them by the gallons. I freeze blackberries with the same method I use to freeze raspberries.
In addition to these bars I also make baked french toast, blackberry muffins , blackberry peach cobbler and blackberry jam with the berries.

Delicious, but not enough to fill a 9" x 13" pan. An 8x8 would be better.
