Kristen's Keys for Blueberry Bars
While an easy recipe, I have a few tips to help ensure your blueberry bars are perfectly sweet and sliceable.
- Use cold butter for the crumble and crust. To give the shortbread a crumbly, and melt-in-your-mouth texture, cold butter is essential.
- Never use fat-free sour cream. Adding sour cream to the blueberry filling, creates a creamy base with just enough tang to balance the sweetness. But never opt for fat-free sour cream as it is made with added stabilizers that will impact the consistency and flavor.
- Best enjoyed chilled. As tempting as it is to dive in after baking, let the blueberry pie bars cool to room temperature than refrigerate to fully chill. As they cill, the filling sets up and the flavor intensifies.

How to Make Blueberry Pie Bars
Because both the crust and crumble are made with a shortbread base, these blueberry bars come together rather easily.
- Prepare Shortbread. Using a food processor or two forks, mix the flour, salt, and sugar together until combined. Add the cubed butter and pulse or mix until the mixture is crumbly. Remove ½ cup of this mixture and set aside for the crumble topping.
- Prebake Crust. Press the remaining shortbread into the baking dish to form the crust and pre-bake for 15 minutes. Partially baking the crust keeps the crust keeps it flaky and tender.
- Prepare Filling. While the crust is baking, use that time to mix together the sour cream, sugar, egg, and blueberries together.
- Layer Blueberry Pie Bars. Once the crust has prebaked, evenly spread the blueberry sour cream mixture over the crust and then sprinkle the reserved shortbread evenly over the blueberry mixture.
- Bake. Bake the bars until the blueberry pie filling is no longer jiggly and the crumble topping is golden brown. Let the bars chill at room temperature for at least 1 hour, then cover and refrigerate, for 2 hours before slicing into bars.
Recipe Modifications
- Egg-Free: Simply omit the egg from the filling. The bars don't set up as well and may need to be enjoyed with a fork, but are still delicious.
- Use Frozen Blueberries: Do NOT thaw the berries, simply fold them frozen into the batter and increase the baking time by 10 minutes.
- Use Different Berries: Feel free to replace the blueberries with blackberries, raspberries, or diced strawberries--similar to my Strawberry Pie Bars.
- Add Lemon: As proven by my recipe for Lemon Blueberry Coffee Cake, blueberries and lemon are a batch made in heaven! For a kiss of lemon flavor, add the zest of 1 large lemon to the blueberry sour cream cream filling.

Ingredients
Shortbread Crust and Crumble
- 1½ cup all-purpose flour
- ¼ cup granulated sugar
- ⅛ teaspoon salt
- ½ cup unsalted butter, cubed and cold
Blueberry Filling
- ½ cup full-fat sour cream
- 1 teaspoon vanilla extract
- ¼ cup granulated sugar
- 1 large egg, slightly beaten
- 4 cups fresh blueberries, washed and dried
Instructions
- Preheat the oven to 350℉. Grease an 8x8 baking dish or line it with parchment paper and set aside.
- In a large mixing bowl or base of a food processor fitted with an s-blade, combine 1½ cup all-purpose flour, ¼ cup granulated sugar, and ⅛ teaspoon salt. Add the cubed butter to the flour mixture in the food processor and pulse until the mixture is crumbly, and the butter is distributed evenly. Alternatively use 2 forks or a pastry blender to mix the butter into the flour mixture.
- Remove ½ cup of the mixture to use for the crumb topping. Press the remaining mixture evenly into the baking dish, using the bottom of a measuring cup or glass if needed to help flatten. Bake for 15 minutes.
- While the crust is baking, mix ½ cup full-fat sour cream, 1 teaspoon vanilla extract, ¼ cup granulated sugar, and 1 large egg in a large mixing bowl. Gently fold in the prepared blueberries.
- When the crust comes out of the oven, pour the blueberry batter over the crust and sprinkle the reserved ½ cup crust batter over the berry mixture evenly.
- Return to the oven and bake for 45-50 minutes or until pie bars are set and the crumble over top is slightly browned.
- Allow the bars to cool for at least an hour before slicing. I recommend allowing the bars to reach room temperature, then cover and refrigerate for 12 hours. This will intensify the flavor and allow the bars to fully set.

Notes
No Food Processor? If you don't have a food processor, use 2 forks or a pastry mixer to combine shortbread mixture.
Sour Cream: Plain Greek yogurt can be substituted for sour cream. Do NOT use fat-free sour cream.
Frozen Blueberries: If using FROZEN blueberries, do NOT thaw the berries before folding into the sour cream mixture and increase the final time by 10 minutes.
Note on Doubling Recipe: To double the recipe, use a 9x13 baking dish and 1 cup (instead of ½ cup) of the shortbread mixture for the crumble.
Storage: Store in an airtight container in the refrigerator for up to 5 days. I don't recommend freezing.

Wish it gave an estimated time for baking.
Hi Laurie! It sounds like you just missed the baking time. It is in step 4 of the recipe card stating to bake 45-50 minutes. I hope you enjoy.
These are everyone’s favorite and so yummy! I can’t wait to make these bars again! Such a great and easy recipe!
Thanks for sharing. I love hearing you enjoyed this recipe.
These are a family favorite around here. The blueberry with the crumble is irresistible!
That crumble gets us every time! Glad you enjoyed Katie!
The crust on these is out of this world. I followed your instructions for using frozen berries, and they turned out perfect.
So glad you enjoyed Krystle! And thanks for letting us know the results with frozen berries!
we LOVE blueberry pie - we have three large blueberry shrubs growing in our front yard. And we're always on the look out for new recipes. This was fantastic and tasted just like my favorite pie without all the effort. Thanks for a great new recipe!
I am so happy you all enjoyed so much! And what a wonderful thing to have blueberry shrubs!
This is the perfect summer treat! It says it can be refrigerated for up to 3 days but there is NO way these will last that long in my home! Delish!
So glad you all enjoyed so much Beth!
Hi! We did enjoy these, but the sour cream mixture disappeared. Should there have been more of it (maybe 1 cup or even more) so that it made a "sauce" around the berries?
Hi Janell. I am glad you enjoyed the flavor, but sorry you were disappointed by the lack of cream mixture. Adding more would make this recipe not sliceable or able to be hand-held.
