Essential Ingredients
Here’s what you’ll need to make this delicious dish:
Fresh Blueberries: Choose ripe berries that are plump and juicy for maximum flavor.
Granulated Sugar: This will sweeten the fruit filling perfectly; adjust based on your taste preferences.
Unsalted Butter: Use cold butter for the crumb topping to achieve that flaky texture we crave.
All-Purpose Flour: Essential for both the crust and crumb; sift it for a lighter texture.
Baking Powder: This is crucial to help your bars rise beautifully; fresh powder works wonders.
Eggs: They bind everything together and add richness; room temperature eggs blend better.
Salt: Just a pinch enhances all the sweet flavors without making things taste salty.
Lemon Zest: A little zest adds brightness and balances the sweetness of the blueberries.
The full ingredients list, including measurements, is provided in the recipe card directly below.

How to Make Blueberry Crumb Bars
Preheat Your Oven: Start by preheating your oven to 350°F (175°C). Grease a baking dish with nonstick spray or line it with parchment paper for easy removal.
Prepare the Crust Mixture: In a mixing bowl, combine flour, sugar, salt, and baking powder. Cut in cold butter until it resembles coarse crumbs. This step ensures your crust will be light and crumbly.
Add Eggs and Lemon Zest: Stir in one egg and lemon zest until just combined. Don’t overmix; we want that tender texture!
Create the Blueberry Filling: In another bowl, mix fresh blueberries with sugar and a dash of lemon juice. Gently fold them into the mixture until evenly coated. The color should be vibrant!
Assemble Everything Together: Press half of the crust mixture into your prepared baking dish evenly. Spread blueberry filling over it and crumble remaining crust on top.
Bake Until Golden Brown: Bake in preheated oven for about 40-45 minutes or until golden brown on top. Let cool completely before slicing—that’s if you can resist!
Enjoy these Blueberry Crumb Bars warm or chilled; they’re perfect anytime! With each bite, you’ll find yourself transported to sun-soaked picnics or cozy family get-togethers filled with laughter—and perhaps an occasional blueberry-stained shirt!
Now go ahead—make these bars today! You won’t regret it when friends start calling you their “baking hero.”
