Blueberry Oat Squares - Starbucks Copycat

Total Time: 1 hr 5 mins Preparation Time: 20 mins Cook Time: 45 mins

Ingredients

• 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 blueberries
• 1/2 cup sugar
• 1/3 cup orange juice
• 4 teaspoons cornstarch

Recipe

• 1 filling: in saucepan, bring blueberries, sugar and orange juice to boil; reduce heat and simmer until tender, about 10 minutes. whisk in cornstarch and boil, stirring, until thickened, about 1 minute. place plastic wrap directly on surface; refrigerate until cooled, about 1 hour or up to 1 day before using.
• 2 base/topping: 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.
• 3 spread the blueberry mixture over the base. crumble the reserved amount of the base/topping over the blueberry mixture.
• 4 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. (make-ahead: cover and refrigerate for up to 2 days or overwrap with heavy-duty foil and freeze for up to 2 weeks.).
