I love when it’s berry season. I’m well known for buying them by the box, and sometimes many boxes at one time. Blueberries make the perfect snack, whether at home or on the go. They are handy for tossing into Homemade Pancakes or making Coffee Cake Blueberry Muffins.

Fresh blueberries mean I can make some of my favourite recipes like Blueberry Lemon Loaf Cake, and Blueberry Shortcake. We also love just plain (but not in taste) Blueberry Cake.

These easy blueberry pie bars have a soft yet formed shortbread-style crust that is so buttery. The same crust mixture doubles down for the crumble topping too. The creamy filling in this easy blueberry dessert is of course, fresh blueberries that are juicy, moist, and almost pop when enjoyed.

This super simple and delicious dessert have the flavors of a blueberry pie without the hassle of making a pie crust.

If you have fresh blueberries on hand, you’ll most likely have everything needed for these squares. You might not even need for a trip to the grocery store. For another dessert bar recipe, try our Pineapple Rhubarb Crumble Bars.

Ingredients and Notes

Blueberries – Fresh blueberries are ideal for their natural juiciness and vibrant flavor, but frozen berries work equally well. You can substitute half the juicy blueberries with blackberries or raspberries for a mixed berry experience.
All-Purpose Flour – This provides a sturdy structure for the crust and crumbly topping, but whole wheat flour can be used as a healthier alternative. Note that whole wheat might result in a denser texture and a more nutty flavor.
Butter- Unsalted butter brings richness and a perfect flaky crumb to the crust and topping. You can substitute with margarine or a dairy-free butter alternative for a vegan-friendly version, though flavor and texture may vary slightly.
Granulated Sugar – Sugar sweetens the blueberry filling and balances the tartness. For a deeper flavor, you might use brown sugar, which adds subtle caramel notes, or reduce the sugar slightly for a less sweet treat.

As always, the full ingredients and recipe is on the printable recipe card at the end of this post.

Recipe Variations

Swap the Berries: Try raspberries, blackberries, strawberries, or a berry medley for a different flavor profile while keeping the same ease and texture. You might want to check out our Strawberry Swirl Cheesecake Bars if you want a bar recipe that has cream cheese.
Add a Vanilla Glaze: Drizzle a simple vanilla glaze over cooled bars for a sweet finish that adds moisture and a hint of warmth to the flavor. You can also do this for our Blueberry Lemon Cupcakes.
Sprinkle with Cinnamon – A subtle dash to a teaspoon of cinnamon in the crumb topping or filling adds warmth and a cozy spice that pairs perfectly with fresh blueberries. It would be a nice touch on our Creamy Vanilla Bars too.

Tips for Success

You can use frozen berries for this recipe. Yet make sure to toss them into a couple tablespoons of flour before adding them to the mixture. This prevents them from bleeding into the bars.
You can substitute greek yogurt for the sour cream, yet it won’t be as robust. Still tasty, but noticeably different. This vintage recipes calls for sour cream for a reason.
Don’t overwork the dough to keep it tender and crumbly. Mixing butter into the flour just until pea-sized crumbs form ensures moist crumbs and a flaky texture without toughness.
You can line the baking pan with parchment paper to make this blueberry dessert easier to remove from the pan to slice.

How to Make Blueberry Pie Bars

Preheat the oven to 325 degrees and grease a 8×8 baking dish.
In a large bowl combine the flour, sugar and butter pieces with an electric mixer until it reaches a consistency that is crumbly.
Set aside 3/4-1 cup of the mixture to use as the topping.
Press the rest of the batter mixture into the prepared dish. Try to press the mixture into an even layer on the bottom.
Bake for 18 minutes or until the edges are golden brown. Remove from the oven and set aside as you make the filling.
In another bowl, whisk the eggs together and then add in the sugar, sour cream, flour and the pinch of salt.
When combined, gently stir in the blueberries.
Pour the mixture on top of the still-warm bottom crust, and sprinkle the reserved crust mixture on top of the filling.
Place the pan into the preheated oven and bake for 50-60 minutes, or until the topping is slightly browned.
Cool this blueberry pie bar recipe before serving to allow some of the juices to settle, but I think this blueberry dessert bar is best when still warm. Enjoy!

Serving Suggestions

Once cooled slightly, cut your dessert into squares of your preferred size. I love these bars when still warm, freshly baked. Our Delicious Blackberry Cobbler is another recipe that is enjoyed in the same way.

Enjoy these delicious blueberry desserts as is. Or, top each bar with some vanilla ice cream or whipped topping, as you would with our Apple Coffee Cake.
