    This section shows how to cook blueberry pie bars in the oven, with step-by-step photos and details about the technique. For full step-by-step instructions, photos and nutritional information see the recipe in the recipe card below. You can print the recipe with or without photos.

    SHAPE THE PASTRY DOUGH: First, cut each sheet of pastry into 4 squares, then score the edges with a knife. Whisk together the egg and water in a small bowl, and brush the edges of the puff pastry squares with the egg wash. Poke the middle part of the squares with a fork 3-4 times. (Do not poke the edges!)

    FILL THE PASTRY: Spoon 2-3 tablespoons of blueberry pie filling into the center of each square. Using a pastry blender, mix all the topping ingredients together in a bowl. Then sprinkle the mixture on top of the blueberry filling.

    BAKE AND GLAZE: Bake for 20 minutes or until puffed up and golden brown. Let the pastries cool for a bit, while you mix the glaze. Drizzle the glaze over the pastries using a fork or a piping bag. Serve.

    RECOMMENDED TOOLS

    Pastry Blender – We love using this pastry blender to work butter into flour and sugar. Works quick and keeps the mess to a minimum.

    TIPS FOR THE BEST BLUEBERRY PUFF PASTRY

    Follow these tips to make the best blueberry pie bars.

    ✔️ Defrost your puff pastry before unrolling it. If you try to unroll it while it’s still frozen it will crack.

    ✔️ Bake until all the puff pastry looks puffed and golden. In some ovens you might need to turn your baking sheet around halfway through cooking to get even cooking.

    ✔️ Allow the pastry to cool a bit before applying the glaze.

    HOW TO STORE

    Refrigerate: Store in an airtight container or ziploc bag and refrigerate or store on the counter for up to 3 days.

    Freeze: Store in an airtight, freezer safe, container. If you’re storing in a zip top plastic bag, try to get as much air out as possible. Freeze for up to 3 months.

    Defrosting: A great way to defrost blueberry pastries is in the refrigerator overnight.

    Reheating: Use the microwave, air fryer, or toaster oven to reheat leftovers.

    FREQUENTLY ASKED QUESTIONS

    For perfect results every time, here are answers to the most common questions about cooking blueberry pie puff pastry bars.

    Is it possible to use other fillings for puff pastries?

    Yes, of course! You can use whatever fruit pie filling you prefer. We recommend trying raspberry, apple, cherry or peach, for example.

    Is it better to use homemade or store bought puff pastry?

    We recommend buying puff pastry premade! We prefer the Pepperidge Farms puff pastry you can find in the freezer section of your local grocery store. However, if you’re feeling ambitious you can always make your own!

    Notes

    • Use lemon juice for the glaze instead of water for a slight hint of tart lemon flavor.
    • Serve while warm or refrigerate for later.

        Hi Lynnie! You can, but they will not be sweet like the pie filling. You can cook them down with sugar in a saucepan until thick and jam-like and then use instead of the pie filling. You might even be able to cut out the sugar if you use especially sweet, fresh blueberries. Let us know how it turns out!
