Preheat oven to350 degrees.
Spray inside of an 8X8 inch baking dish with non-stick cooking spray.
Using two parchment paper strips, line the inside of the baking dish with the strip allowing them to hang over the edge. This will create a “handle” to pull the bars from the dish after baking.
Combine brown sugar and the next four ingredients.
Using your fingers or a pastry cutter, incorporate the butter into the brown sugar mixture until crumbly.
Press 2 cups of the crumbly mixture evenly into the prepared pan.
Spread the raspberry jam over the mixture leaving about 1/4 inch edge on the outside jam-free.
Sprinkle remaining crumbs over the jam.
Bake for 30-35 minutes.
Cool bars. Remove from baking dish and cut into bars.
