These Easy Blackberry Pie Bars combine a luscious homemade blackberry filling with a buttery gluten-free crust, all topped with a crumbly streusel. Perfectly sweet and tangy, they make a delightful treat for any occasion and are made with simple ingredients including vegan butter for a dairy-free twist.

Ingredients

For the Filling:

  • 3 Cups Blackberries (fresh or frozen)
  • ½ Cup Sugar
  • 1 Tablespoon Lemon Juice
  • 1½ Tablespoons Cornstarch
  • 1½ Tablespoons Water

For the Crust:

  • 1¾ Cups Gluten Free Flour
  • ½ Cup Sugar
  • ½ Teaspoon Salt
  • ¼ Teaspoon Baking Soda
  • 10 Tablespoons Vegan Butter, cold and cut into cubes
  • 1 Teaspoon Vanilla Bean Paste
  • 1 Teaspoon Lemon Zest

Instructions

  1. Preheat and Prepare Pan: Preheat your oven to 350°F (175°C). Line an 8-inch square baking pan with parchment paper, leaving enough overhang to lift the bars out easily later.
  2. Cook the Filling: In a saucepan over medium-low heat, combine blackberries, sugar, and lemon juice. As the berries release their juices, mash about half of them with a potato masher to create a chunky consistency.
  3. Thicken the Filling: Mix cornstarch and water to create a slurry, then stir this into the blackberry mixture. Continue to cook, stirring frequently, until the filling thickens and bubbles for 2-3 minutes. Remove from heat and let it cool.
  4. Make the Crust Dough: In a food processor, pulse together the gluten-free flour, sugar, baking soda, salt, vegan butter, vanilla bean paste, and lemon zest until the mixture forms a crumbly dough. It may seem dry, but this is expected.
  5. Assemble the Bars: Press about two-thirds of the dough evenly into the bottom of the prepared baking pan to form the crust. Spread the cooled blackberry filling evenly over the crust. Crumble the remaining dough over the blackberry layer to form the topping.
  6. Bake the Bars: Bake in the preheated oven for approximately 45 minutes or until the filling is bubbly and the topping is lightly browned.
  7. Cool and Serve: Remove the bars from the oven and allow them to cool completely in the pan. Once cool, carefully lift the bars out using the parchment paper overhang. Optionally dust with powdered sugar before slicing and serving.

Notes

  • You can use fresh or frozen blackberries for convenience; just thaw frozen berries before cooking.
  • If you prefer a smoother filling, mash the berries more thoroughly before cooking.
  • Make sure the vegan butter is very cold to help create a crumbly texture in the crust.
  • These bars keep well in an airtight container at room temperature for 2 days or refrigerated for up to 5 days.
  • Dusting with powdered sugar is optional, but adds a nice finishing touch.
