This was quite good. There was a very subtle peanut butter flavor, but we really couldn't taste the jam. I used low sugar jam and I'm not sure if that the problem. It puffed up nicely in the oven. You definitely need to watch when you do the final broiling of the sugar topping. It goes really fast. (I managed to set off my son's smoke detector when I baked this at his house!) We served it hot right out of the oven, but my daughter said she almost liked it better cold the next day. Thanks for posting such a unique bread pudding recipe.
