Preheat the oven to 350 degrees. Line a 9-inch square baking pan with parchment paper. Cut enough parchment so ends overhang on 2 sides so you can lift the bars out after they've cooled for easy cutting.
Bake 50 minutes or until fruit is bubbling and top is golden. Cool completely on wire rack. Grasp ends of parchment and lift crumble from pan. Slice into 16 bars.
