Fresh Blueberry Crumb Bars

"We love fruit desserts in the summer, and these crumb bars are a go-to around here. I adapted this recipe from one that my mother used to make when I was a kid. And guess what? This recipe couldn’t be any easier if it tried! The crumb topping is the same mixture as the crust. And the middle portion is mostly just berries. These Blueberry Crumb Bars are easy + delicious, and the recipe makes a huge tray."
