BLUEBERRY BAR INGREDIENTS
Blueberry Bars consist of simple pasty dough that serves as both the bottom and the crumble topping for your bars, and, of course, an ooey-gooey blueberry filling.
To make the dough, you will need flour, sugar, butter, and shortening. In addition to the flour and fats, the dough also calls for an egg, which helps the dough to stay together, baking powder (a leavener), along with vanilla and salt for added flavor.
The blueberry filling consists of blueberries, sugar, salt, lemon juice and zest, and cornstarch. The cornstarch and sugar meld with the blueberries to create a flavorful filling that holds together perfectly. Don’t skip out on the lemon, especially if you’re using ripe blueberries. The lemon adds a necessary burst of acid to the Blueberry Bars and heightens the overall flavor profile.
HOW TO MAKE BLUEBERRY BARS
- Prep — Position rack in the lower third of the oven, and preheat oven to 375°. Have ready a greased, 9×13″ baking dish.
- Make the Crust — If you’ve ever made a homemade pie crust, then you know how seriously easy to make pastry dough from scratch. You can use either the food processor or a pastry blender to do it. Mix the dry ingredients, cut in the butter, add the egg, and stir to combine!
- Make the Filling — The Blueberry Bar filling is a simple matter of adding blueberries, sugar, cornstarch, lemon juice and zest to a bowl and stirring to combine.
- Assemble the Bars — Once the crust comes together, the majority of it gets transferred to a 9×13″ casserole dish. Be sure to leave some for the topping though! The bottom portion is gently patted down to create a solid layer of dough. Then, the blueberry mixture is poured over the solid layer of dough, and the dough that remains is crumbled over the top.
- Bake – The blueberry bars are off to the oven and baked up until the filling is a beautiful, bubbly mess, and the crust is a perfect golden brown.

Easy to make blueberry bars featuring a fresh blueberry filling with lemon, and a simple pastry dough.
- 2 3/4 cup all-purpose flour
- 1/2 cup granulated sugar
- 1 1/4 teaspoon fine sea salt
- 1 teaspoon baking powder
- 8 tablespoons cold, unsalted butter cut into cubes
- 8 tablespoons cold shortening (regular, not butter-flavored), cut into cubes
- 1 egg slightly beaten
- 1 teaspoon pure vanilla extract
- 4 cups fresh blueberries washed and dried
- 1/3 cup granulated sugar
- 4 teaspoons cornstarch
- 1 teaspoon lemon zest
- Juice of 2 lemons
- 1/4 teaspoon fine sea salt
-
Position rack in the lower third of the oven, and preheat oven to 375°. Have ready a greased, 9x13" baking dish.
-
Add the flour, sugar, salt, and baking powder to the bowl of a food processor fitted with a paddle attachment. Pulse to mix. If you do not have a food processor, use a large mixing bowl and a whisk.
-
Add the cold, cubed butter and shortening and pulse until the mixture resembles small peas speckled throughout the dry ingredients. Or, you could use a pastry cutter to cut in the fats.
-
Add the egg and vanilla, and pulse combine. If you're not using a food processor, stir with a wooden spoon until evenly incorporated. Set aside until ready to use.
-
In a large mixing bowl, combine blueberries, sugar, cornstarch, lemon zest, lemon juice, and salt. Stir to combine.
-
Add about 2/3's of the dough to the bottom of the greased casserole dish. Gently use your hands to pat the dough out evenly across the dish. Pour the blueberry filling evenly across the dough, and crumble the dough that remains over the top.
-
Bake for 45 minutes, or until the crust is golden-brown. Place on a wire rack and allow to cool 15 minutes before cutting. Serve and enjoy.
