Blueberry Crumb Bars
Description
These Blueberry Crumb Bars consist of a dough mixed from flour, granulated and brown sugar, baking powder, salt, eggs, vanilla, and chilled butter, which is pressed partly into a baking dish to form the base. The filling mixes fresh blueberries with lemon juice, sugar, and cornstarch which thickens during baking to hold the berries together. Finally, the remaining crumb dough is sprinkled over the berry layer.
Baked at 375°F for about 40 minutes, the bars develop a golden crumbly top and firm crust underneath surrounding the sweet and tangy blueberry filling. The lemon juice brightens the berry flavor, balancing the sugars in the crust and filling. Allowing the bars to cool before cutting helps them set into neat squares that hold their shape.
This recipe can be easily adapted with other fresh berries or extra lemon zest for a more pronounced citrus note. The crumb topping contrasts in texture with the juicy filling, creating a balanced dessert with moderate sweetness and tartness.
