Easy Peasy Blueberry Pie Bars

These blueberry pie bars have a crisp, buttery crust piled high with blueberries & a crumble-y top for a perfectly portable take on pie.
When it comes to pie, I like crisp, buttery crusts piled high with fruit and these blueberry pie bars deliver on both counts. Bonus: no crust rolling necessary!

In fact, the same dough recipe does double duty here, pressed into the bottom of the pie pan for the aforementioned gloriously golden base and then crumbled on top for a zero effort streusel-y finish.

This recipe has been through a fair few iterations and originally started life as more of a shortbread-like base. While delicious, the crust puffing that came from a base with leavener didn’t respond well to a juicy fruit filling and was just a little too soft for my liking.

The resulting slightly soggy middles between fruit and crust after a day on the counter didn’t win any awards from me, either. I wanted these blueberry pie bars to taste just as good on day 3 as day 1, just like a good pie should. Sogginess, begone!

So the next step was to pare down the recipe, testing out a crust that was more pie-like, without egg and leaveners.

My first few batches were all baked at once, in that I simply pressed in the base, layered in the blueberry filling and topped it off with the crumble before baking altogether.


While that does work just fine, I didn’t feel the end result was pie-like enough to warrant what I’d already decided were supposed to be blueberry pie bars.

So I tested the next version with a speedy little par bake of just the bottom crust.

This gives a beautifully golden base that really creates that warm, crispiness of a good pie crust and takes these bars from generic fruity squares to truly Pie Bar territory!

Now, if you do like a slightly softer base, you could skip the par bake step – rolling those 8 – 10 minutes into the rest of the bake time. Or, you could swap the metal baking dish for a glass dish for a less crispy finish.

But, really, why would you want to? I probably feel a little too strongly about my love of crispy crust. Maybe.

The hint of lemon in these bars does two things. Firstly, that kiss of zing really brings out the flavor of the fruit and contrasts nicely with the richness & sweetness of the crust. Secondly, the acid from the juice helps the blueberries create that gorgeous purple-y hue.

For the record, I did not exaggerate or enhance that color in the photos, although that may be a little hard to believe – that’s allllll blueberry magic!

Easy Peasy Blueberry Pie Bars

These blueberry pie bars have a crisp, buttery crust piled high with blueberries & finished with a crumble-y top for a perfectly portable take on pie.

  • Author: Rachael Bryant / Meatified
  • Prep Time: 20 minutes
  • Cook Time: 40 minutes
  • Total Time: 1 hour
  • Yield: 16 squares 1x
  • Method: oven

Ingredients

Scale

Crust:

  • 2 cups / 250 g all purpose flour
  • 1/3 cup / 70 g granulated sugar
  • 1/3 cup / 65 g light brown sugar
  • ¼ tsp salt
  • 2/3 cup / 150 g unsalted butter, slightly softened

Filling:

  • 1 tbsp / 12 g arrowroot starch
  • 1/3 cup / 70 g granulated sugar
  • 1 ½ tbsp / 22 ml lemon juice & zest from one lemon
  • 3 cups / 430 g blueberries
  • Pinch of salt

Instructions

PREP: Preheat the oven to 350 F / 175 C and line an 8 x 8 inch / 20 x 20 cm square metal pan baking pan with parchment paper.

MIX: In a large bowl, mix together the flour, both sugars and salt. Use a pastry cutter to cut the butter into the flour until it resembles coarse crumbs and is evenly distributed through the mixture.

RESERVE: Save 1 cup / 155 g of the mixture, about one third of the dough. Pop it into the fridge to use for the topping later.

PRESS: Sprinkle the rest of the crust mixture evenly over the base of the prepared pan, starting with the corners and edges for even thickness throughout. Working from the outside in, press down the crust so that it firms up into a single layer. If you like, use the bottom of a measuring cup to press down and level out any finger dimples for the smoothest finish.

BAKE: Place the pan on the middle shelf and bake until lightly golden and just dry on the surface with a slight golden edge and a light puff, about 8 – 10 minutes.

COMBINE: While the crust is par baking, mix together the arrowroot, sugar, lemon juice and zest in a medium mixing bowl until it resembles a slightly thickened slurry. Add the blueberries and stir together until they are coated in the sugar mixture.

TOP: Transfer the par baked crust to a trivet and increase the oven temperature to 375 F / 190 C. Spoon the blueberry mixture onto the hot crust, being mindful of the hot pan and your hands! Squeeze together the refrigerated reserved crust mixture so that it clumps up lightly, then sprinkle it across the surface of the fruit. Let the blueberries peek through the crumbles in places.

FINISH: Return the pan to the oven and bake until the blueberries are just bubbling at the edges and the crumble topping is golden brown, about 30 minutes. If you like, sprinkle with a little turbinado sugar while still warm for a lovely bit of crunch. Let cool to room temperature for several hours for the cleanest slices.

Notes

  • If your have time, let the butter sit out at room temperature so that it softens slightly and is easier to cut into the flour.
  • If you prefer a softer crust, you can skip the par bake and add the 8 – 10 minutes onto the fruit baking time, for a total of 38 – 40 minutes. Or you could try using a glass pan for less crispness. This makes for a more cookie like finish and won’t hold together quite as well, so it’s your choice.
  • You can increase the lemon juice up to 2 tablespoons / 30 milliliters if your lemon is especially juicy or large.
