This dessert features a crumbly, lemon-zested crust and a luscious blackberry filling with a perfect balance of natural sweetness and bright lemony tartness.

You’ll need:

For The Crust And Topping:

  • 3 cups of all-purpose flour
  • 1½ cups of sugar
  • ¼ teaspoon of salt
  • Zest of 1 large lemon 
  • ½ cup of unsalted sweet cream butter, cold and cut into small cubes
  • 3 eggs, slightly beaten 

For The Blackberry Filling:

  • 4 cups of fresh blackberries, cut in half
  • 1 tablespoon of fresh-squeezed lemon juice
  • 1 tablespoon of cornstarch 
  • ¾ cups of sugar

PRO TIP:

Blackberries should be stored in the refrigerator after purchasing or picking. They are best used within 3 days.

Substitutions And Additions

BERRIES: For this recipe, you can use any kind of berries you’d like in place of the fresh blackberry filling.

Try blueberries, raspberries, or even a mix of berries. You can use strawberries as well, although you need to slice them, and the added juice in them will make your bars turn out with a slightly different texture.

LEMON ZEST: Orange zest can offer a citrusy twist if you’re out of lemons. The aroma and flavor will be distinct, lending a new dimension to your bars.

How To Make This Blackberry Pie Bars Recipe

Once you make the tasty crust, you can assemble the dessert by layering the crust, blackberries, and a sweet, crumbly topping.

STEP ONE: In a stand mixer, add the flour, sugar, salt, and lemon zest. On low speed, mix the flour mixture until combined.

STEP TWO: Add in the cold unsalted butter and mix until you get pea-sized pieces of butter.

OUR RECIPE DEVELOPER SAYS

Making the crust can be done in the bowl of a food processor, or in a large bowl with a pastry blender.

STEP THREE: Add in the beaten eggs and mix until a crumbly dough comes together.

STEP FOUR: Line a 9×13-inch baking dish with parchment paper, allowing for overhang so that you can lift the cooled bars out of the pan to cut.

Press ⅔ of the dough evenly into the bottom of the pan and set aside.

STEP FIVE: In a large mixing bowl, combine the blackberries, lemon juice, cornstarch, and sugar and mix until combined.

PRO TIP:

Don’t forget to rinse the blackberries before adding them to the bowl. Cleaning fresh blackberries is easy. The best way is to pour them into a colander. Discard any errant leaves or stems. Set the colander in the sink and run water over the berries. Leave it to drain for a few minutes.

STEP SIX: Pour the blackberry mixture over the top of the crust and even it out with a rubber spatula.

STEP SEVEN: Crumble the remaining pie dough over the blackberry filling.

STEP EIGHT: Bake in an oven preheated to 350°F for 45 to 50 minutes or until the top crust appears slightly golden brown.

PRO TIP:

Oven temperatures vary and may need to be recalibrated periodically to ensure they are accurate. Make sure to check your bars at the lower end of the recommended baking time.

STEP NINE: Pull the baking dish out of the oven and set it aside to cool completely before cutting the bars.

    Can these be made with frozen berries? Should they be thawed and drained well first? Blackberry season is done but I have quite a few bags of frozen ones

    Thanks

    5 stars
    I haven’t made this yet but I’m wondering if I can use canned fruit instead as I have so much on my shelf and if so what do I omit from the recipe and does the cooking time and temperature change?
