Ingredients

  • granulated white sugar
    1 ¼ c
  • lemon zest
    1 tbsp
  • unsalted butter

    softened

    1 c
  • vanilla
    1 tsp
  • all purpose flour
    2 ½ c
  • salt
    ¾ tsp
  • fresh raspberries
    1 ¾ c
  • fresh blueberries
    1 ½ c
  • fresh blackberries
    1 ¾ c
  • granulated white sugar
    ¾ c
  • cornstarch
    ¼ c
  • lemon zest
    1 tbsp
  • lemon juice
    1 tbsp

Directions

For the crust

  1. 1

    Preheat the oven to 375℉ (190℃). Spray a 9×9 inch pan with non-stick spray and line it with parchment paper.

  2. 2

    Add the sugar and lemon zest to a large bowl. Rub the lemon zest and sugar together with your fingertips to extract the most lemon flavor from the zest.

  3. 3

    Add in the softened butter and vanilla. Cream together with an electric mixer on high speed for 1-2 minutes until very light and fluffy.

  4. 4

    Add in the flour and salt. Mix on low speed just until combined. The dough should form into large clumps.

  5. 5

    Set aside 1/3 of the dough for the crumble, and use 2/3 of the dough for the crust.(If you want to be very precise, use a kitchen scale to weigh the entirety of the dough and divide by three so you know exactly how many grams of dough should be used for the topping! :) )

  6. 6

    Chill the portion of dough reserved for the crumble in the fridge while working on the rest of the bars.

  7. 7

    Press the larger portion of dough into the bottom of the prepared 9x9 inch pan. A small offset spatula really helps to smooth out the dough into one even layer.

For the berry filling

  1. 1

    Add the raspberries, blueberries and blackberries to a large bowl.

  2. 2

    Add in the sugar, cornstarch, lemon zest and lemon juice. Gently toss with a spatula to coat the berries. Let the berries sit for a few minutes to absorb the cornstarch and make a bit of a juice.

  3. 3

    Then, pour berry filling over the crust.

  4. 4

    Remove the crumble from the fridge and sprinkle it evenly over the berries.

  5. 5

    Bake the bars for 65-70 minutes, or until they're golden brown on top and the berry filling is bubbling.

  6. 6

    Let the berry crumble bars cool completely on a wire rack before cutting to ensure the filling has time to firm up. Once cooled, cut into 16 bars and enjoy!

About this Recipe

Imagine biting into the essence of summer: sweet, tangy, and bursting with fresh fruit flavor. These Triple Berry Crumble Bars deliver just that, combining a buttery shortbread crust, a luscious berry filling, and a delightful crumble topping that will transport you to a sunny picnic.

What makes these Triple Berry Crumble Bars truly special is the exquisite balance of textures and vibrant flavors. You'll love the tender vanilla lemon shortbread cookie crust, which perfectly cradles a generously thick, sweet-tart filling of raspberries, blueberries, and blackberries. It's all crowned with a rich, buttery shortbread crumble, ensuring every bite is a symphony of crumbly and jammy goodness.

Prepare for a dessert that sings of summer's bounty. Each bar offers a delightful contrast: the slight tang of fresh berries, the bright notes of lemon, and the comforting sweetness of vanilla-infused shortbread. The berries soften into a wonderfully jammy consistency as they bake, creating a vibrant, fruity layer. Meanwhile, the shortbread crust remains tender, providing a sturdy base, and the crumble topping adds an irresistible, crumbly texture. This dessert is a proven crowd-pleaser, ideal for any casual gathering or a special treat on a warm evening.

Customization & Variations

While the classic combination of fresh raspberries, blueberries, and blackberries is unbeatable, you can easily adapt this recipe. Feel free to experiment with other fresh berries like sliced strawberries or tart huckleberries if they're in season. For an extra bright kick, you could add a little more lemon zest to the crumble topping mixture.

These delightful crumble bars are a fantastic stand-alone dessert, but they also shine when served warm with a scoop of vanilla bean ice cream or a dollop of freshly whipped cream. They are ideal for potlucks, picnics, barbecues, or simply as a sweet ending to a family meal.
