I found this recipe on Allrecipes.com. I followed some suggestions made there and came up with a few tweaks of my own.
I replaced 1/2 the butter from the original recipe with applesauce, added whole wheat flour, cinnamon, SimplyFruit jam, extract and fresh berries.
Preheat oven to 350° F (175 degrees C). Using an 8 inch square pan, line with foil and grease with cooking spray.
In a mixing bowl combine brown sugar, flours, baking soda, salt, cinnamon, and rolled oats. Blend in the butter to form a crumbly mixture (I use hand/standing mixer for this). Press 1-1/2 cups of the mixture into the bottom of the prepared pan.
In a microwave safe bowl, warm jam to spreading consistency. Add 1 teaspoon vanilla/almond extract, mix well. Spread the jam to within 1/4 inch of the edge (this is important so it doesn't burn). Sprinkle the remaining crumb mixture over the top, and lightly press it into the jam.
Bake for 35 to 40 minutes in preheated oven, or until lightly browned. Allow to cool before cutting into bars.
