Blueberry Crumb Bars Ingredients
• Here’s what you need to create these delightful Blueberry Crumb Bars:
For the Crust and Topping
- Unsalted Butter – Provides richness and moisture for the crumb mixture. For a dairy-free option, substitute with coconut oil.
- All-Purpose Flour – Creates structure for the crust and topping. For gluten-free, use a gluten-free 1:1 baking flour.
- Old-Fashioned Oats – Adds texture and heartiness to the crumb topping; quick oats can be used but may yield a softer topping.
- Light Brown Sugar – Adds sweetness and a hint of caramel flavor; can be substituted with coconut sugar for a lower glycemic index.
- Cinnamon – Provides warmth and spice to the crumb topping; nutmeg can be used for a different flavor profile.
- Salt – Enhances flavor; use kosher salt for better control in baking.
For the Filling
- Blueberries – The star of the recipe, fresh blueberries add natural sweetness; frozen blueberries can be a substitute, just adjust baking time.
- Lemon Juice – Brightens the blueberry flavor; lime juice can be used as an alternative.
- Cornstarch – Thickens the blueberry mixture for a better texture in the bars; arrowroot powder is a suitable substitute.
How to Make Blueberry Crumb Bars
-
Preheat the oven to 350°F and grease an 8×8-inch baking pan. This step is crucial for ensuring your bars come out perfectly baked and easy to remove!
-
Mix melted butter, flour, oats, brown sugar, cinnamon, and salt in a medium bowl until you achieve a crumbly texture. It should resemble wet sand, making for a deliciously buttery topping.
-
Reserve 1 cup of the crumb mixture; press the remaining mixture firmly into the greased pan to form a solid crust. Aim for an even layer that will hold the filling beautifully.
-
Combine the blueberries, sugar, lemon juice, and cornstarch in another bowl. Toss gently to coat the blueberries for a vibrant filling that bursts with flavor.
-
Spread the blueberry mixture evenly over the crust. This juicy layer is what makes the bars truly delightful!
-
Sprinkle the reserved crumb topping over the blueberries, ensuring every corner is covered. This crown of crumbs will bake to a golden perfection.
-
Bake for 30-50 minutes—30 minutes for fresh blueberries and 50 for frozen—until the bars are set and the top is golden brown. The aroma will fill your kitchen with sweetness!
-
Cool completely on a wire rack, and if you want cleaner slices, freeze for 15-30 minutes before cutting into squares. Patience pays off!
Optional: Serve with a dollop of whipped cream for an extra touch of indulgence.

Make Ahead Options
These Blueberry Crumb Bars are perfect for meal prep enthusiasts! You can prepare the crumb crust and the blueberry filling up to 24 hours in advance, storing them separately in the refrigerator.

Blueberry Crumb Bars Recipe FAQs
How do I select ripe blueberries for the recipe?
Absolutely! Choose fresh blueberries that are plump, firm, and free of dark spots. They should have a deep, rich color and a slight sheen. If you’re opting for frozen blueberries, ensure they are solidly frozen without clumping, which indicates they haven’t thawed and refrozen.
What’s the best way to store Blueberry Crumb Bars?
To keep your Blueberry Crumb Bars at their best, store them in an airtight container. At room temperature, they’ll stay fresh for up to 3 days. If you prefer storing in the fridge, they can last up to 1 week to maintain their moisture. Always remember to keep them away from direct sunlight!
Can I freeze leftover bars?
Yes, you can! Wrap individual bars in plastic wrap and then seal them in an airtight container or freezer bag. This way, the bars will maintain their flavor and freshness for up to 4 months. When you’re ready to enjoy, simply thaw them at room temperature or briefly reheat in the oven at 350°F for about 10 minutes for a freshly baked taste!
What should I do if my crumb topping is too wet?
If you find that your crumb mixture is too wet, don’t worry! Simply add a bit more flour or oats, one tablespoon at a time, until it reaches a crumbly texture similar to wet sand. This will ensure you get that beautiful, crunchy topping for your Blueberry Crumb Bars.
Are there any dietary considerations for this recipe?
Very! These bars can easily accommodate dietary preferences. For a dairy-free version, substitute the butter with coconut oil. You can also use gluten-free 1:1 flour in place of all-purpose flour. As always, check for any allergies specific to fruits, like strawberries or other variations you might use. It’s always better to be safe!
How can I enhance the flavor of my Blueberry Crumb Bars?
Of course! To elevate the taste of your Blueberry Crumb Bars, consider adding a teaspoon of vanilla extract to the blueberry filling or a pinch more of cinnamon to the crumb mixture. You could even squeeze a little more lemon juice over the blueberries before baking for that extra zing!
