These Best Blueberry Bars are a simple, rustic dessert that highlights the natural sweetness of blueberries. A buttery, tender crust doubles as both the base and crumbly topping, surrounding a juicy layer of blueberries lightly sweetened with maple syrup. As the bars bake, the berries soften into a vibrant filling while the crust turns golden and slightly crisp. Chilled before slicing, the bars set into neat squares with a soft, jammy center and a rich, buttery bite—perfect for showcasing fresh summer berries or enjoying year-round with frozen fruit.
