    Why You Will Love This Blueberry Pie Bars Recipe

    • Easy to Make. Unlike pie, there's no rolling pin required! The dough is easy to spread into the pan.
    • Simple Ingredients. We're using fresh blueberries and a handful of basic baking ingredients to make these blueberry bars.
    • Customizable. There are plenty of variations when it comes to making the fruit dessert bars giving you some options to use up ingredients you have on hand or using the flavors you prefer.

    If you like simple fruity desserts like this, take a look at this Caramel Peach Upside Down Cake, Blueberry Sheet Cake, Puff Pastry Apple Tart, Blueberry Monkey Bread, Blueberry Cream Cheese Pie or our Blueberry Cheesecake Bars.

    Ingredients

    Only a handful of ingredients are needed to make this blueberry dessert, and you probably already have most in your kitchen. Here's a look at what you need.

    Ingredients needed to make blueberry bars on the table before mixing.
    • Crust: Made with all-purpose flour, granulated sugar, unsalted butter, and salt. Make sure your butter is very cold and grated to make mixing easy and achieve the right texture.
    • Blueberries: I love these bars using fresh blueberries but you can also use frozen.
    • Maple syrup: Adds sweetness with a bit more depth than regular sugar.
    • Lemon juice: A bit of acidity to balance out the sweetness.
    • Cornstarch: For thickening the filling. You can also use arrowroot powder or tapioca flour.
    • Vanilla extract: Adds a natural warmth, sweetness, and aroma to the filling. Almond extract also works for a slightly different flavor and essence.

    Variations

    • Change Up the Fruit. If blueberry isn't your jam you can swap the blueberries out for another berry or other fruit such as fruit.
    • Skip the Homemade Pie Filling. If time is short, you can use canned pie filling instead. Any flavor works to make pie bars you love.
    • Add a Glaze. Drizzle the bars with a simple glaze made with milk and powdered sugar.
    • Gluten-Free. Swap the regular flour with your favorite 1-to-1 gluten-free flour blend.
    • Brown Sugar. Swap the granulated sugar in the crust for the more complex flavor of brown sugar.

    How To Make Blueberry Pie Bars

    Here are the step-by-step photos and instructions for making these easy blueberry pie-filling bars. Check the recipe card further down on the page for the complete instructions.

    Before you start mixing, preheat your oven and prepare an 8x8 inch baking pan with parchment paper, leaving some overhang to make it easy to remove after baking.

    Dry ingredients whisked together in a bowl.

    Step 1: Combine the flour, sugar, and salt in a large mixing bowl.

    Shredded butter added to the flour.

    Step 2: Grate the cold butter into the flour mixture using a box grater.

    Recipe Tips

    • Making the Crumb Mixture. Be sure to use very cold butter and that it's mixed evenly with the flour to ensure the best flavor and texture possible for the crust.
    • Cool Completely. Allow the bars to cool completely before cutting for neat and clean slices.
    • Serving: The perfect easy-to-make sweet ending for two of my favorite weeknight easy recipes BBQ meatloaf and margarita grilled chicken. These bars are perfect for picnics, cookouts, and potlucks too.
    • Storing: Cover with plastic wrap or aluminum foil and store in an airtight container in the refrigerator for 3-4 days or in the freezer for up to 2 months.

    Recipe FAQs

    Can I double this blueberry bars recipe?

    Yes, you can! Swap the baking pan for a 9 x 13 instead of a square pan. The bars may be a bit thicker so I recommend checking them and continue cooking as needed.

    How do I know my blueberry pie bars are done?

    Use the cooking time as a gauge and watch the top closely for color. What you're really looking for though to determine doneness is that the blueberry filling is heated and bubbly. Make sure to check for bubbles in the middle as it's the last part of the pan to cook all the way.

    What's the easiest way to cut blueberry bars?

    Wait until they are fully cooled to remove them from the pan. They will be quite soft when they first come out of the oven and need time to set up. Then grasp the edges of the parchment paper that are extended beyond the edge of the pan, remove the entire square of bars, and place it on a cutting board. Use a sharp knife to cut into squares. Wipe the blade as needed to keep the cuts clean.
