    The secret to easily fit the dough into the sheet pan is to use parchment paper when rolling it out which makes it a breeze to not only roll and chill but also to decorate, assemble and serve.

    Simply remove the pie bars from the sheet pan by lifting them out with the parchment paper. Then slice and transport to picnics, parties and potlucks without worry of leaving a dish behind.

    Ingredients

    • Lemon pastry crust – A large batch sweet lemon version of my favorite All Butter Pie Crust recipe made with the addition of lemon zest, extra sugar and an egg yolk for extra sturdiness. It’s sturdy, flaky and super flavorful.
    • Berries – these blackberry blueberry pie bars with sliced nectarines and freshly picked blueberries and blackberries have a delicious balance of sweet and tart but any fruit and berries can be substituted.
    • Nectarines – a great stone fruit to use in pie because they don’t require peeling but you can substitute other stone fruit like peaches or apricots or leave them out. Apple, peach, cherry and even chocolate are all fabulous fillings for this sheet pan dessert.
    • Sugar
    • Heavy cream- to coat the pastry before baking.
    • Flour – for the pastry crust and also to thicken the pastry filling to ensure a light, juicy filling that cuts cleanly and isn’t the least bit runny. Cornstarch can also be substituted in the filling.
    • Egg – white and yolk separated. The yolk is used in teh pastry crust and the egg white is whipped and spread on top.
    • Salt

    Step by step instructions

    1. Preheat oven to 325 degrees Fahrenheit. 
    2. Prepare lemon pastry crust by combining flour, sugar, salt and lemon zest in a large bowl. Cut cold butter into small pieces and toss with mixture, working butter in with fingertips until only small pieces remain. Toss with egg yolk and ice water and stir just until the dough comes together. 
    3. Divide dough into two large pieces and place each on a piece of parchment paper the size of your sheet pan.
    4. Top each piece of dough with another similar size piece of parchment and roll each piece of lemon pie dough to fit the parchment.
    5. Transfer pastry sheets to large sheet pans and place both in the refrigerator or freezer to chill until firm, at least 30 minutes.
    6. Meanwhile, gently stir together filling ingredients. Blueberries, blackberries, nectarines, flour, sugar, salt and lemon juice.
    7. Once pastry is chilled remove parchment from the top of one piece and decorate as desired with cut outs, designs, etc.
    8. Then remove the top of the second piece of dough and gently press into the corners of the sheet pan to form the bottom crust.
    9. Top bottom crust with filling.
    10. Place the decorated dough directly onto filling with the parchment paper side facing up. Gently peel off parchment and press dough together around the edges of pan to lightly seal using dough scraps to fill in where needed. 
    11. Brush with heavy cream.
    12. Then whip reserved egg white until light, fluffy and almost meringue like. Brush fluffy egg white around the crust in random spots then sprinkle coarse sugar evenly over top.
    13. Bake until crust is browned and filling is bubbly, 40-55 minutes.
    14. Cool slightly and serve.
    15. Enjoy!

    Instructions

    • Preheat oven to 325 degrees Fahrenheit.

    • Divide dough into two large pieces and place each on a piece of parchment paper the size of your sheet pan. Top with another similar size piece of parchment and roll each piece of lemon pie dough to fit the parchment.

Gently peel off parchment and press dough together around the edges of pan to lightly seal using dough scraps to fill in where needed. 
    • Brush with heavy cream or milk then whip reserved egg white until light, fluffy and almost meringue like. Brush fluffy egg white around the crust in random spots then sprinkle coarse sugar evenly over top.
