We planned a picnic with my sister and her family recently, and two things were certain: I wanted to make these pie bars, and my sister wanted to make potato salad. So we had the important things figured out. I ended up making pizza wraps (the first time I’d ever made wraps!), and she brought deviled eggs. We both threw some cherries into our picnic baskets, because that’s what you do in the summer.
It was a nice hike in the mountains, and a nice lunch, but mostly I just wanted to get to dessert. And that wasn’t the only waiting I had to do, as these took about three times longer to bake than I was expecting. I was mystified at the time, but eventually I figured out the culprit – the blackberries that I most definitely had not gotten around to defrosting before baking.
They were certainly worth waiting through the hike (which I enjoyed anyway) and the lunch (same) and the extra oven time (not so much), because they were a perfect casual summer dessert. They had the perfect balance of fruit and buttery dough. They were the perfect cap to a great picnic in the woods.
Crust and topping:
3 cups (14.4 ounces) all-purpose flour
1½ cups (10.5 ounces) sugar
½ teaspoon salt
1½ cups (3 sticks) unsalted butter, chilled
4 large eggs
2 cups (14 ounces) sugar
1 cup sour cream
¾ cup (5.25 ounces) flour
¼ teaspoon salt
zest of ½ lemon
1 teaspoon almond extract
2 (16-ounce) packages frozen blackberries, thawed and drained
1. Adjust the rack to the middle position and heat the oven to 350 degrees. Spray a 9-by-13-inch baking pan with nonstick spray.
2. To make the crust and topping, combine the flour, sugar, and salt in the bowl of a food processor. Pulse a few times to mix. Cut the butter into ½ inch cubes and add it to the flour mixture. Process until the butter is evenly distributed but the mixture is still crumbly, 30-60 seconds.
3. Reserve 1½ 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, until the dough is set and lightly browned on top.
5. Cool at least 1 hour before cutting into bars, or scoop out of the pan to serve cobbler-style.
