Blackberry Shortbread Bars

Crust: Preheat the oven to 350°F. Prepare a 9- by 13-inch baking pan with butter or cooking spray; set aside. Combine the flour, sugar and salt in a food processor for about 45 seconds. Cut the butter into ½ inch cubes and process with the flour mixture for 30 seconds or until the butter is evenly distributed but the mixture is still crumbly. Reserve 1½ cups of the crust mixture to use as a topping. Press the remaining crust mixture firmly into the bottom of the prepared pan. Bake for about 25 minutes or until golden brown; allow to cool for at least 10 minutes before adding the filling.

Filling: Combine the eggs, sugar, sour cream and flour in a large bowl. Fold in the blackberries. Spoon the fruit filling evenly over the crust and sprinkle the reserved crust mixture over the filling. Bake for 45 to 55 minutes or until the top is lightly browned. Let cool for at least 1 hour before cutting into bars. Makes 24 bars.
