For the base, mix together the dry ingredients in a large bowl and add the wet ingredients. Press the mixture evenly into the pan.
Spread the jam evenly across the base layer.
Combine the topping ingredients and spread evenly on top of the jam.
Bake for 30 minutes or until the topping begins to turn brown.
Cool completely on a wire rack. Cut into 15 bars and store in an airtight container for up to 4 days. Alternately, these bars may be frozen until ready to serve.
