Blueberry Pie Bars

Blueberry pie is such a classic, but I’m not much of a pie-maker.

I’m indifferent about pie crust and making a pie just to eat filling sounds like way too much work.

With pie bars, there’s no crust to roll out, no mixer or rolling pin needed, and there’s an abundance of sweet blueberry filling. Now we’re talking.

The bars have a soft yet crisp, buttery, shortbread-style crust. The crust mixture does double duty as the crumble topping. Love it when that happens so there’s one less step and one less bowl to wash.

There’s a creamy filling that tops the crust, which gives the bars a soft yet dense texture.

Blueberries top the filling layer and they soften and release their juices while baking. All those juicy berries help to create extremely moist bars.

I used frozen blueberries because they’re cheaper, readily available year round, and went straight from freezer to mixing bowl. I always bake with frozen. If you have fresh, they’d be lovely and you’ll need to reduce the baking time.

The crumbly bits on top of the bars add welcome texture and dimension to the soft filling and juicy berries. I love streusel or crumble toppings and will take crumble topping over pie crust any day.

The bars are super soft and tender in the interior while the crust is firmer. The contrast of soft and firm makes you want to keep on taking bite after bite of these blue beauties.

Between the firm crust, the soft filling, the juicy blueberries, and the sandy crumbles, the bars have so many wonderful textures and flavors in every thick bite.

They taste fancy enough to serve at a special event, luncheon, or brunch, yet are so homey and comforting.

I’ll take a pie bar over pie any day.

Yield: one 8x8-inch pan, 9 generous pieces

Prep Time: 15 minutes

Cook Time: 60 minutes

Total Time: 90 minutes, for cooling

Ingredients:

Crust and Crumble Topping
1/2 cup unsalted butter, melted
1/2 cup granulated sugar
1/4 cup light brown sugar, packed
1 1/2 cups all-purpose flour
pinch salt, optional and to taste

Filling
1 large egg
heaping 1/2 cup plain or vanilla Greek yogurt; or sour cream (lite is okay)
1/3 cup granulated sugar
2 teaspoons vanilla extract
1 tablespoon all-purpose flour

Blueberry Layer
12 ounces (2 cups) blueberries (fresh or frozen; I used frozen and didn't thaw)
1/3 cup granulated sugar (or 1/2 cup if berries are sour)
2 tablespoons lemon juice
2 teaspoons cornstarch

Directions:

Preheat oven to 350F. Line an 8-inch square pan with aluminum foil and spray with cooking spray; set aside. Lining the pan will really help with cleanup and is recommended.
Crust and Crumble Topping - In a large, microwave-safe bowl melt the butter, about 1 minute on high power.
Add the sugars and whisk to combine.
And the flour, optional salt, and stir to combine. Mixture will be very dry and sandy with some larger, well-formed crumble pieces.
Set a heaping 3/4 cup crumble mixture aside.
Transfer remaining mixture to prepared pan, and using a spatula or your fingers, hard-pack the mixture to create an even, smooth, flat crust; set aside.
Filling - In a medium bowl, add the egg, Greek yogurt, sugar, vanilla, and whisk to combine.
Add the flour and whisk to combine.
Evenly pour filling over the crust and jiggle pan to help distribute it or smooth it with a spatula; set aside.
Blueberry Layer - In a separate medium mixing bowl, add all filling ingredients and toss to combine. If sugar hasn't dissolved fully or still has crystals, that's okay because it liquifies while baking.
Evenly distribute blueberry mixture over the filling.
Evenly sprinkle with the reserved heaping 3/4 cup crust mixture. Before sprinkling, I squeeze the mixture in my palm to encourage bigger crumble pieces to form.
Bake for about 60 minutes, or until edges are bubbling quite vigorously and there's some bubbling in the center. Crumble topping should appear set and very pale golden. I used frozen berries without thawing and the pan was very cold going into the oven. If using fresh berries, baking time will be reduced, but I'm not sure by how much, I'd guess at least 10-15 minutes, possibly less. Watch your bars, not the clock, when evaluating doneness. Place pan on a wire rack and allow bars to cool for at least 1 to 2 hours (overnight is even better) before slicing and serving. If you try to slice bars before they've cooled completely, they'll be extremely messy and could fall apart. Bars will keep airtight at room temperature for up to 1 week, in the fridge for up to 10 days (they're good slightly chilled if you like chilled pie), or in the freezer for up to 6 months.

Hi Averie – I made these pie bars last week and they were a huge success, so I made them again today for superbowl sunday. This time I added a 1/2 tsp of almond extract to the crust, which added a nice flavor. I also tried your blueberry crumble bars last week. These pie bars are definitely more sweet dessert-y as you mentioned, and they were my family’s favorite between the two. Needless to say we wiped out our stock of frozen blueberries! Thanks for the delicious and unique recipes! Love your site!

Thanks for trying the recipe and I’m glad it came out great for you! And also for trying the crumble version. These are definitely more dessert-ey and nice to know which ones you preferred.

I can I tell you how grateful I am for this recipe. I have used it over the last two years for all kinds of events. Backyard barbecues and picnics as Well as formal high tea event. Mostly For my friends. I have done many different variations…. like making more crumble (or adding oats and coconut) and adding different fruits like mulberries, but I always come back to the same recipe. I have seven children and cannot thank you for the ease of this recipe. I basically use one bowl and stir each step accordingly. I wish I could post pics, but you get the idea. A HUUUUUGE THANK YOU!!!!! You have brought many smiles too many people.

Thanks for the glowing feedback and so glad this recipe is an ultimate hit for you! And kudos to you for being a mom of 7!!
