We have black raspberries growing along our back fence, so I needed something I could modify for DH's diabetic diet. We did this one tonight, and it was yummy!! I used 1 Tablespoon of Splenda in the custard (instead of 2T Sugar) and mixed equal amounts of Splenda and Brown Sugar for the topping. It was a bit of standing and stirring at the stove, but oh, so worth it :D
It's an online recipe, so here is the link:
