Best Lemon Blueberry Bar Recipes

LEMON-BLUEBERRY BARS

Steps:

• Heat oven to 325 degrees and line a 9-inch square baking dish with parchment paper so it hangs over the edges on all sides by a few inches. (You may need to use two pieces of parchment.)
• Make the crust: In the bowl of a food processor, pulse to combine the flour, confectioners' sugar, lemon zest and salt. Add butter and pulse until a crumbly dough forms, about 10 seconds. (Or mix dry ingredients in a bowl and use pastry cutter to cut in butter, clumping the mixture together in your hands until it holds together.) Press dough into prepared pan. Bake until light golden, 25 to 35 minutes.
• As crust bakes, make the curd: In a medium pot, whisk together the granulated sugar, lemon juice, egg yolks, whole eggs, cornstarch and fine sea salt until well combined. Place over medium heat and stir with a heatproof rubber spatula (or wooden spoon), making sure to scrape around the sides and edges of the pot, until mixture is simmering and thickened, 5 to 10 minutes.
• Bring mixture to a boil and let cook for about 30 seconds, but no longer than 1 minute. Immediately strain through a fine mesh sieve into a bowl. Stir in butter, lemon zest and lime zest, and stir until butter melts. Stir in blueberries.
• Pour mixture over crust, then stir to evenly distribute berries. Return to oven, and bake until blueberries begin to burst and curd starts to turn golden around the edges, 33 to 45 minutes. Transfer to a wire rack to cool to room temperature. Chill in the refrigerator until thoroughly cold before cutting, at least 3 hours. Dust lightly with confectioners' sugar right before serving.

LEMON-BLUEBERRY BLONDIE BARS

Steps:

• Preheat the oven to 350 degrees F (175 degrees C). Grease and line a 9-inch square baking pan with parchment paper, allowing a 1-inch overhang.
• Melt butter in a small saucepan over medium heat. Add white chocolate and stir until chocolate is melted and incorporated with the butter. Scrape mixture into a large mixing bowl and whisk in the brown sugar until smooth. Whisk in the lemon juice, zest, and salt until all is combined. Whisk in egg, egg yolk, and vanilla extract.
• Stir in flour. Using a rubber spatula, fold in blueberries. Scrape batter into the prepared pan and smooth into an even layer; it will be a bit thick.
• Bake in the preheated oven until golden brown, 35 to 40 minutes. Transfer to a wire rack and allow blondies to cool for at least 15 minutes in the pan. When ready to serve, lift the blondies out of the pan using the parchment paper overhang and place on a cutting board.
• To make the glaze: Whisk powdered sugar and lemon juice together in a small bowl until smooth. Drizzle over the blondies. Slice and serve.
