Equipment You’ll Need
To make these blueberry pie bars, you’ll need an 8×8 inch baking dish and an electric mixer. These tools will help you create that perfect crust and creamy filling.
How to Make Blueberry Pie Bars
Prepare the Crust and Topping
Begin by preheating your oven to 325°F. In a large bowl, combine 1½ cups of flour, ¾ cup of sugar, and the chilled butter. Use an electric mixer to mix until the mixture resembles crumbs.
Bake the Crust
Reserve ¾ to 1 cup of the crumb mixture for the topping. Press the remaining crumbs evenly into the bottom of your greased baking dish. Bake for 18 minutes or until the edges are golden brown. Remove it from the oven and let it cool slightly.
Make the Blueberry Filling
While the crust bakes, whisk 2 large eggs in a separate bowl. Add in 1 cup sugar, ½ cup sour cream, ⅓ cup flour, and a pinch of salt. Gently fold in the fresh blueberries, ensuring they are coated in the creamy mixture.
Assemble and Bake the Bars
Pour the blueberry filling evenly over the warm crust. Sprinkle the reserved crumb mixture on top. Bake for 50-60 minutes, or until the topping is slightly browned. Let the bars cool before cutting into squares, although they taste best when slightly warm.
Tips for Perfect Blueberry Pie Bars
Make sure to use fresh blueberries for the best flavor. If they are not in season, frozen blueberries can be a suitable alternative. Also, ensure your butter is chilled for a flakier crust!
Variations for Your Pie Bars
If you’re feeling adventurous, try using raspberries, blackberries, or a combination of your favorite berries in place of blueberries. Each variation brings its own unique flavor to the bars!
Serving Suggestions
Serve your blueberry pie bars warm with a scoop of vanilla ice cream or a dollop of whipped topping. They also pair wonderfully with a cup of coffee or tea for an afternoon treat.
Storing and Freezing Blueberry Pie Bars
How to Store Leftovers
Cool the bars completely before storing to prevent condensation from making them soggy. Place them in an airtight container at room temperature for up to 3 days or refrigerate for up to 1 week.
How to Freeze Blueberry Pie Bars
To freeze, wrap the bars tightly in plastic wrap and aluminum foil or place them in an airtight freezer container. They can be frozen for up to 2 months. Thaw overnight in the refrigerator for the best texture.
