Blackberry Pie Bars

Ingredients:

1. Crust and Topping
2. 3 cups all-purpose flour
3. 1 1/2 cups sugar
4. 1/4 tsp salt
5. 1 1/2 cups (3 sticks) unsalted butter, chilled
6. 
   
7. Fruit Filling
8. 4 large eggs
9. 2 cups sugar
10. 1 cup sour cream
11. 3/4 cup flour
12. pinch salt
13. zest of 1/2 lemon
14. 1 tsp almond extract
15. 2 (16-oz) packages frozen blackberries, thawed and drained

Directions:

1. To make the crust and topping, preheat the oven to 350 degrees. Grease a 9x13 inch baking pan.
2. Combine the flour, sugar, and salt in the bowl of a food processor. Pulse a few times to mix. Cut the butter into 1/2-inch cubes, and add to the flour mixture. Process until the butter is evenly distributed but the mixture is still crumbly, 30-60 seconds.
3. Reserve 1 1/2 cups of the mixture to use as the topping. Press the remaining mixture into the bottom of the pan, and bake 12-15 minutes. Cool for at least 10 minutes.
4. To make the filling, whisk the eggs in a large bowl, then add the sugar, sour cream, flour, salt, lemon zest, and almond extract. Gently fold in the berries and spoon the mixture over the crust. Sprinkle the remaining flour mixture evenly over the filling, and bake 45 to 55 minutes.
5. Cool at least 1 hour before cutting into bars, or scoop out of the pan to serve cobbler-style.
