Soft, nutty shortbread, fresh blueberries, and tangy lemon zest combine to make these sweet Blueberry Pie Bars! They're perfect for summer and any potlucks or get-togethers that you might have coming up.
Preheat oven to 350°F (175°C). Line a 9"x 13"x 2" baking pan with parchment paper and grease the lining and any exposed parts of the inside of the pan. If you prefer, skip the lining and grease the pan.
Stir together the flour, pecans, and salt. Set aside.
Using an electric mixer on medium speed, beat the butter and confectioners' sugar until light and fluffy. Mix in the vanilla.
Reduce the mixer speed to low. Gradually add the flour mixture, mixing just until a loose dough forms.
Transfer slightly more than half of the mixture to the prepared pan. Press evenly into the bottom of the pan. Top with the blueberries.
Stir together the sugar and lemon zest. Sprinkle over the blueberries. Crumble the remaining shortbread mixture over the berries.
Bake 45 to 50 minutes, or until the bars are golden brown. Cool in the pan completely (about 2 hours) before cutting into bars.
