Blueberry Pie Bars Recipe

• Preheat the oven to 350 degrees F. Spray an 8-by-8-inch baking pan with cooking spray.
• Line the pan with parchment paper so that it hangs over on two sides.
• Spray the parchment.

For the crust:

• In the bowl of a food processor, combine the butter, sugar, flour, cinnamon and salt. Process until the mixture starts to come together and clump, 1 minute.
• Remove 3/4 cup and reserve; press the remaining crust mixture evenly into the prepared baking pan. Set aside.

For the filling:

• In a medium bowl, whisk together the egg, sour cream, sugar, lemon juice, flour, cornstarch, vanilla extract and cinnamon until smooth.
• Mix in 1 cup of the blueberries. Pour the filling mixture over the crust, shaking the pan gently to settle the custard and berries.
• Pour the remaining 1 cup blueberries over the top, spreading them evenly.
• Take the reserved crust and sprinkle it over the top of the berries, squeezing the mixture in your hands to encourage large lumps.
• Bake for 1 hour. Let cool. Remove the bars from the pan and cut into 9 pieces. Refrigerate until ready to serve.
