Blueberry Crumb Bars are a delicious fusion of blueberry pie and blueberry crumble. It has a buttery crust, just like pie. It boasts a tantalizing blueberry filling in the center, similar to both pies and crumbles. Yet it incorporates the mouthwatering crumble topping characteristic of crumble desserts.
