    Nothing much better than a shortbread cookie crust, sweet blueberry filling, and crumbling topping! These Blueberry Crumb Bars are irresistible. #blueberries #cookies #dessert

    Blueberry Pie Bars are easier than pie to make and a perfect treat to make with fresh or frozen blueberries! Made with a buttery shortbread cookie base, a creamy, sweet blueberry filling, and a generous crumb topping, these Blueberry Bars are absolutely delicious.

    If you love blueberries, not only will you love these Fresh Blueberry Bars, but you will also love Blueberry Vegan Pancakes and Whole Wheat Blueberry Muffins.

    From the buttery shortbread to the sweet blueberries to the creamy custard, these Blueberry Pie Bars are the perfect summer dessert.

    They are sweet. They are buttery. They are creamy. Absolute perfection!

    Not to mention, these blueberry bars are incredibly easy to make.

    Notes on Ingredients

    • Shortbread Base and Crumble: The crumble and the base of these pie bars is the same mixture and is made with flour, butter, sugar and salt--much like my recipe for Classic Shortbread Cookies.
    • Blueberries: While fresh berries are best, frozen blueberries work as well, so you can enjoy this treat year round.
    • Custard Filling: The creaminess in these pie bars comes from a mixture of sour cream, vanilla, eggs, and sugar together. Feel free to replace the sour cream with plain Greek yogurt if desired.

    How to Make Blueberry Bars

    • Preheat the oven to 350 degrees F and grease an 8x8 baking dish or line with parchment paper and set aside.
    • Mix together the flour, ¼ cup sugar, a dash of salt together.
    • Add in cold butter and mix together until the butter is incorporated into the flour mixture and resembles sand.
    • Take out a ½ cup of the pie crust mixture and set aside for the blueberry bars crumb topping.
    • Press the remaining batter evenly in the glass baking dish.

    • Bake the shortbread cookie base for 15 minutes.
    • In a mixing bowl, mix together the sour cream, remaining sugar, egg, and vanilla together until well combined.
    • Gently fold in the blueberries.
    • Remove the shortbread crust from the oven and spread the sour cream blueberry pie filling over the shortbread crust.
    • Sprinkle the reserved pie crust over top of the blueberry pie bars evenly.
    Assembled Pie Bars in Baking Dish
    • Bake the bars until the blueberry pie filling is set and the crumble topping is golden brown.
    • Cool bars completely before storing in the refrigerator. These bars can be enjoyed immediately once cooled, but the flavor is best if enjoyed after chilling for a couple of hours.

    Storage

    Cool the Blueberry Pie Bars until they reach room temperature. Cover and refrigerate the bars for up to 3 days.

    You can freeze these bars as well, if well wrapped and stored in an airtight container for up to 1 month. Defrost in the refrigerator overnight before enjoying. The texture will be a bit softer after freezing, but still taste delicious.

    Recipe FAQs

    Is it necessary to prebake the shortbread base?

    Yes, this step helps to seal the base of these bars which keeps the blueberry filling from seeping into the crust as it bakes, which would make the crust soggy.

    Is there a trick to cutting uniform slices?

    I find it is best to slice into bars after refrigerating the blueberry bars for several hours first. This gives the filling time to set up and thicken and makes cutting the bars much easier. Plus the flavor is more developed.

    Can you use frozen berries?

    Yes! DO NOT THAW the frozen berries, mix into the sour cream mixture right from the freezer. If using frozen berries, you will need to add an additional 10 minutes to the bake time.

    What is the best way to prepare the shortbread base and topping?

    You can mix together the shortbread crust in a food processor fitted with the pastry blade, with a pastry cutter, or with 2 forks. Personally, I opt for my food processor to make quick work of preparing the shortbread.

    Instructions

    • Preheat oven to 350. Grease an 8x8 baking dish or line with parchment paper and set aside.
    • In a large mixing bowl, combine flour, ¼ cup sugar, and dash of salt. Mix in the butter with a paddle mixer, pastry blender, or 2 forks until crumbly, and butter is distributed evenly. Reserve ½ cup of the mixture for later. With the remaining batter, press it evenly in the glass baking dish. Bake for 15 minutes.
    • While crust is baking, mix together yogurt/sour cream, remaining ¼ cup sugar, vanilla and egg together. Gently fold in the blueberries.
    • When the crust comes out of the oven, pour the blueberry batter over the crust and sprinkle the reserved ½ cup crust batter over the berry mixture evenly. Return to the oven and bake for 45-50 minutes or until pie bars are set and crumble over top is slightly browned.
    • Allow to cool for at least an hour before slicing. The bars are BEST if enjoyed after refrigerating for 12 hours before slicing and enjoying.

    Equipment Needed

    • 8x8 baking pan
    • Parchment Paper

    Notes

    Sour Cream Substitute: Plain Greek yogurt can be substituted for sour cream. 
    Frozen Berries: If using FROZEN blueberries, do NOT thaw and increase baking time by 10 minutes. 
    Leftovers: Store leftover bars in refrigerator for up to 3 days.

      Hi! If I were to make this in a 9x12 pan, would I double the recipe? Or make it 1.5x?
      Thank you!!

        If using a 9x13 pan (standard size) you would double 🙂
