Blackberry Pie Bars Recipe: This Blackberry Danish Bar recipe is a keeper! I’m not usually a big fan of berry desserts and pies, but I love these Danish pie bars! Of course, the crust is my favorite part. It is flaky and tender, yet thick enough that you can eat the bars with your hands. No fork necessary. Basically, the sweet berry filling and tender, flaky crust are magical together. Yum!
