These bars are one of my favorite desserts in the world! I know rhubarb season is over, but if you grew it in your garden this year, maybe you froze some - you can also buy frozen rhubarb at many grocery stores. If you can't find any frozen rhubarb, this recipe is worth saving to make next year. My slightly blurry photo doesn't capture it too well (sorry about that), but these bars consist of a buttery crust, topped with a layer of rich rhubarb custard, finished with...CREAM CHEESE FROSTING. It just doesn't get any better than that, my friends.
