Blackberry Oat Bars



  • 2 cups quick-cooking oats

  • 1 cup all-purpose flour

  • 1 cup brown sugar

  • 1⁄2 teaspoon salt

  • 1⁄2 teaspoon baking soda

  • 3⁄4 cup butter, softened

  • 3 cups fresh blackberries or blueberries or raspberries

  • 1⁄2 cup sugar

  • 1⁄3 cup orange juice

  • 4 teaspoons cornstarch


For the Blackberry Filling:

  1. In saucepan, bring blackberries, sugar and orange juice to boil; reduce heat and simmer until tender, about 10 minutes.
  2. Whisk in cornstarch and boil, stirring, until thickened, about 1 minute.
  3. Place plastic wrap directly on surface; refrigerate until cooled, about 1 hour or up to 1 day before using.

For the Base and Crumble Topping:

  1. In a large bowl, stir together the oats, flour, brown sugar, salt and baking soda. Cut in the butter to form a crumbly mixture. Reserve 1 1/2 cups of the crumbs, and pat the rest evenly into the bottom of a greased 9 x 13 inch pan.
  2. Spread the blackberry mixture over the base. Crumble the reserved amount of the base/topping over the blueberry mixture.
  3. Bake at 350 degrees F until light golden, about 40-45 minutes. Let cool completely on rack as these cut better when they are fully set.
