Blueberry Oat Squares - Starbucks Copycat

lilsweetie's Note:

These wholesome bars are just like Starbucks blueberry squares (if not better!) My favorite thing about this recipe is the oatmeal base/crumble topping. It is so versatile and makes enough for a generous amount on the top and bottom because c'mon... isn't that everyone's favorite part?! I use this same oatmeal crust recipe with a multitude of different fillings, including swapping strawberries for the blueberries.

• Total Time: 1 hrs 5 mins
• Prep Time: 20 mins
• Cook Time: 45 mins

Ingredients:

Serves: 24

Yield: 24.0 squares

• 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

Directions:

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.).

I love Starbucks blueberry oat squares! There's a simple step missing in the recipe where to spread the blueberries onto the base. That's easy to figure out. I used a 16 oz pkg of frozen blueberries. The flavor is right on, although they seemed to have a bit more oat texture than Starbucks. They also wanted to crumble apart. But, hey - I went after the taste and got it. Thanks!
