Instructions

- Bake crust for 14 to 16 minutes, until lightly golden and set. Transfer to a wire rack and cool for 15 minutes.

- Bake bars for another 45 to 50 minutes, or until topping is golden and filling slightly bubbly. Cool completely in pan on a wire rack. Just before cutting, chill in the freezer for 15 minutes. Carefully lift parchment and place bars on a cutting board; cut into squares with a sharp knife.
