For a nice seasonal dessert or treat with coffee or tea, serve these zesty, fruity, crumb-topped bars warm with a scoop of ice cream or dollop of whipped cream. Or let the bars cool, then cut into very small bars and serve on a cookie tray.
Tip: If you happen to have raspberry jam with seeds, simply heat the jam (in a microwave-safe bowl) in the microwave oven until fluid, then stir and strain the jam through a fine sieve to remove the seeds.
