Blueberry Crumb Bars Ingredients
For the Crust
- Granulated Sugar – provides sweetness; for a deeper flavor, consider using brown sugar.
- Lemon Zest – adds a fresh citrus aroma; a splash of lemon juice works as a substitute if needed.
- All-Purpose Flour – forms the base; for gluten-free options, swap with a gluten-free flour blend.
- Baking Powder – helps the crust rise; make sure it’s fresh for the best texture.
- Salt – balances sweetness; omit if you’re using salted butter.
- Unsalted Butter – adds richness; coconut oil is a great dairy-free alternative.
- Egg – binds the mixture; for a vegan option, try flaxseed meal mixed with water.
For the Blueberry Filling
- Fresh Blueberries – the star of the bars, bursting with flavor; frozen blueberries can be used, just increase cornstarch slightly.
- Lemon Juice – brightens up the blueberries; bottled lemon juice can be a quick stand-in.
- Cornstarch – helps thicken the filling; arrowroot powder can be used instead.
For the Topping
- Remaining Crust Mixture – after prepping the filling, the leftover mixture will create a delightful crumb topping.
Step-by-Step Instructions for Blueberry Crumb Bars
Step 1: Preheat Oven & Prepare Pan
Begin by preheating your oven to 375°F (190°C). While it warms, take a 9×13-inch baking pan and line it with parchment paper, leaving some overhang. This will make it easy to lift your baked Blueberry Crumb Bars out later. Set the prepared pan aside as you work on the next steps.
Step 2: Combine Dry Ingredients
In a spacious mixing bowl, combine granulated sugar and lemon zest, mixing until fragrant and well-blended. Next, add the all-purpose flour, baking powder, and salt, and whisk together until fully incorporated. This dry mixture will serve as the foundation for both the crust and topping of your delicious Blueberry Crumb Bars.
Step 3: Incorporate Butter & Egg
Cut cold, unsalted butter into the dry mixture using a pastry cutter or your fingers until it resembles coarse meal with pea-sized crumbs. Then, crack an egg into the bowl and mix until the dough comes together. This step is crucial for achieving that buttery, crumbly texture which will make your bars irresistible.
Step 4: Build the Crust
Take half of the crumb mixture and press it firmly into the bottom of your prepared baking pan to form a base. Use your fingers or the back of a measuring cup to ensure it’s evenly distributed and creates a solid foundation for your Blueberry Crumb Bars. Aim for a compact layer that will hold up the juicy filling.
Step 5: Prepare Blueberry Filling
In a separate bowl, gently toss fresh blueberries with lemon juice, sugar, and cornstarch until they are well-coated. This mixture will create a luscious filling that bubbles beautifully during baking. Spread the blueberry concoction evenly over the crust, ensuring every bite of your Blueberry Crumb Bars is packed with flavor.
Step 6: Add Topping
Sprinkle the remaining crumb mixture generously over the blueberry filling, ensuring it covers the entire layer. This crumb topping will create a crisp and delicious contrast to the soft blueberries underneath. Evenly distribute the crumbs to avoid any bare spots that might lead to unequally baked bars.
Step 7: Bake
Place your pan in the preheated oven and bake for 40-45 minutes. Keep an eye on them, as you want the topping to turn a lovely golden brown and the filling to bubble around the edges. The sweet aroma of the baking Blueberry Crumb Bars will fill your kitchen, tempting everyone nearby!
Step 8: Cool & Cut
Once baked, remove the pan from the oven and let it cool completely on a wire rack. This cooling time is important for the filling to set. Once cooled, use the parchment overhang to lift the entire batch out of the pan, and cut into squares. Serve your Blueberry Crumb Bars and enjoy the delightful fruits of your labor!

Expert Tips for Blueberry Crumb Bars
-
Use Cold Butter: Ensure your butter is cold when making the crust; this will help create the desired crumbly texture instead of a dense bar.
-
Refrigerate Before Cutting: Let the bars chill in the refrigerator for at least an hour before slicing them. This helps achieve cleaner, neater squares that look more appealing.
-
Monitor Baking Time: Keep a close eye on your Blueberry Crumb Bars during the last 5-10 minutes of baking to prevent over-browning or burning.
-
Consider Fresh vs. Frozen: While fresh blueberries are ideal, if using frozen, increase the cornstarch slightly to absorb excess moisture and maintain the right consistency.
-
Add a Glaze: For extra sweetness, try drizzling a simple powdered sugar glaze over the top of the cooled bars for a delightful finishing touch.
Storage Tips for Blueberry Crumb Bars
Room Temperature: Store Blueberry Crumb Bars in an airtight container at room temperature for up to 2 days to maintain their freshness.

Blueberry Crumb Bars Recipe FAQs
How do I choose the best blueberries?
Absolutely! When selecting fresh blueberries, look for plump, firm berries with a deep indigo color. Avoid any that have wrinkles or dark spots all over, as these can indicate overripeness. If possible, buy organic blueberries to reduce pesticide exposure and enjoy their natural flavor to the fullest!
What’s the best way to store Blueberry Crumb Bars?
To keep your Blueberry Crumb Bars fresh, store them in an airtight container at room temperature for up to 2 days. For longer storage, place them in the fridge for up to 5 days. This will keep the bars moist and delicious, ensuring every bite is as good as the first!
Can I freeze Blueberry Crumb Bars?
Of course! To freeze your Blueberry Crumb Bars, wrap them individually in plastic wrap and place them in a sealed freezer bag. They’ll stay fresh for up to 3 months. When you’re ready to enjoy them, simply thaw in the fridge overnight or leave them at room temperature for a couple of hours before serving.
Why did my crumb topping turn out dense?
Very! If your crumb topping doesn’t have that light, crumbly texture, it may be due to warm butter. Cold butter is essential to achieve that perfect crumbly texture, so be sure to use cold ingredients and handle the mixture gently. If you find it’s too dense, try using a pastry cutter to mix better and incorporate more air into the topping.
Are these bars suitable for my pet?
It’s important to note that while blueberries are safe for dogs in moderation, these Blueberry Crumb Bars contain sugar and butter that aren’t suitable for pets. Always consult your veterinarian before sharing any homemade treats with your furry friends!
