Blackberry bars - recipe on Forkd!

• ½ cup butter, soft
• ½ cup light brown sugar
• 1 cup flour
• ¼ teaspoon baking soda
• ⅛ teaspoon salt
• 1 cup rolled oats
• ¾ cup blackberry jam

Heat the oven to 350 degrees. Butter a square pan (8 inches) or a round tart pan. Cream the butter and sugar together. Then mix in the rest of the ingredients, except the jam. With your fingers press 2 cups of the mixture into the bottom of the pan. Ensure an even spread. Using a spoon spread the jam on top of the crumble almost to the edge, then sprinkle the remaining crumb mixture over the top. Bake 35 to 40 minutes (until the oats on top turn golden brown) and cool on a rack.
