Be sure to create filling in advance as it must cool before being incorporated.


1 cup old fashioned rolled oats
1 cup quick-cooking oats
1 cup all-purpose flour
1 cup packed brown sugar
1/2 teaspoon salt
1/2 teaspoon baking soda
3/4 cup butter, softened
3 cups blueberries (fresh or frozen)
1/2 cup sugar
1/3 cup orange juice
4 teaspoons cornstarch


  1. In saucepan, bring blueberries, 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. Pour into a bowl. Place plastic wrap directly on surface. Refrigerate until cooled and bearing a consistency similar to that of a jam, about 1 hour or up to 1 day before using.
  3. In a large bowl, stir together oats, flour, brown sugar, salt and baking soda. Add butter to form a crumbly mixture.
  4. Reserve 1 1/2 cups of crumbs; pat remaining dough evenly into the bottom of a greased 9 x 13 inch pan. Spread blueberry mixture over the base. Crumble reserved amount of the base/topping over the blueberry mixture.
  5. Bake at 350F until light golden, about 40-45 minutes. Let cool completely on rack before cutting. Store in refrigerator.
