Blueberry Crumb Bars
These Blueberry Crumb Bars have a buttery crumb crust and a juicy, plump blueberry filling, all topped with more buttery streusel for a delicious bar treat!
If you love blueberries and crust as much as I do, then this dessert should come with a warning label, because it is ADDICTIVE! I’m not even joking, I think I ate half of this pan myself. It’s that buttery crust and crumble with the sweet, plump blueberries…I die!
These Blueberry Crumb Bars, so super simple to throw together! Six ingredients for the crust, four ingredients for the fruit, and VOILA! Throw that dish into the oven!

Now, I actually hate using fresh fruit for desserts because I feel like it’s a waste of a crisp, juicy, healthy snack, but because I got a 2lb package of blueberries for $3.50, I decided it was okay, maybe just this once. That’s why you will see me using frozen berries/fruit for most of my baking recipes on this blog. I just like to eat fruit while it’s fresh, unaltered, in it’s whole, pure form. It usually gets gobbled up before it gets baked into anything.
I will admit that fresh blueberries bake better than frozen ones though. Especially for muffins and quick breads, etc. It was fun to use fresh blueberries in these bars, even though they get all jellied up like pie filling.
I have heard of those farms where you can go to and pick your own fruit for a discounted price. As far as I know, I don’t live anywhere near one of those, so I will have to keep my baking to the frozen variety and eat the fresh fruit for my snacking pleasure, unless of course, I snag a super deal like I did with the blueberries for these Blueberry Crumb Bars.
Anyway, I hope you decide to make these, and share them with your friends because you might eat the whole pan yourself!
Blueberry Crumb Bars
Ingredients
Crust/Crumble:
- 3 cups (360 g) all-purpose flour, (stir, spoon & level)
- 1 cup (200 g) granulated sugar
- 1 tsp baking powder
- ½ tsp salt
- 1 cup (226 g) butter, cold, cut into Tablespoons
- 1 large egg
Blueberries:
- 4 to 5 cups (560-700 g) fresh blueberries
- ½ cup (100 g) granulated sugar
- 4 tsp cornstarch
- 3 Tbsp lemon juice
Instructions
- Preheat oven to 375 degrees Fahrenheit. Lightly grease a 9×13-inch baking dish.
- In a medium bowl, whisk together the flour, sugar, baking powder and salt. Use a fork or pastry cutter to blend in the butter, and then the egg (the dough will be crumbly). You can alternately do this process in a food processor. Press ¾ of dough into the prepared pan.
- In a separate large bowl, whisk together the sugar, cornstarch and lemon juice. Gently fold in the blueberries to coat evenly with the sugar mixture. Spread the blueberry mixture evenly over the crust, including all the juices.
- Crumble the remaining dough evenly over the blueberry layer.
- Bake for 45 to 50 minutes, or until the top is light golden brown. Cool completely before cutting into squares. Leftovers can be stored in an airtight container or wrapped in plastic wrap at room temperature or in the refrigerator.

Do you think these will freeze well?
Yes, they should freeze just fine. Put parchment paper between any layers. I’d say they’d freeze well for up to 2-3 months.
We had something like this at a potluck today!
Awesome! They are so tasty!
Do you think peaches would work in this desert as well? I have a ton 😉
Absolutely! I have a peach variation here: https://www.dessertnowdinnerlater.com/peach-crumb-bars/
If you enjoy fresh blueberries, now is the time to stock up! Freeze them to enjoy them throughout the year.
Oh believe me I do! Thanks for the tip!
I would love to make this all year. How much frozen fruit? Thanks! Appreciate the pics!
It would be the same as fresh blueberries, 4 to 5 cups. I would increase the cornstarch to 1 1/2 Tablespoons though, because the frozen fruit will give off more liquid than the fresh.
Do they need to be thawed?
No, but allow for extra baking time, if needed. It needs to bubble in the center. If the crust gets too brown before that happens, cover it with foil.
These crumb bars look amazing, Amber! I love blueberries and am a sucker for anything with a crumble topping. I would be tempted to eat this entire pan by myself too – love these!
these crumb bars look delicious! i definitely need to make the recipe, perfect for my afternoon sweet treat when my sugar cravings hit.
Thanks Thalia! You will love them!
Looks delicious! We are dessert lovers in my home. This dessert wouldn’t stand a chance. LOL
Oh I send most of the desserts with my husband to his work because I have no control! 😉
Pure perfection! These bars are simple and delicious.
I am seriously contemplating making these again, just for fun, because eating half the pan myself wasn’t enough, lol.
