Lemon-Blueberry Blondie Bars


Summer is a time to simply take it easy, and that's so much of what I love about this buttery blondie recipe. Not only does it capitalize on one of the most iconically refreshing summer flavor romances of all (lemon + blueberry forever), but it couldn't be simpler to whip up at a moment's notice. You may very well have every ingredient called for in your kitchen right now, and all you need is 25 hands-on minutes to pull these scrumptious lemon-blueberry bars together. P.S. If you happen to be a real citrus fanatic, consider doubling the glaze recipe for a more generous drizzle.

1 9x9-inch pan


For the Blondies:

  • ¾ cup unsalted butter

  • 2 ounces white chocolate, finely chopped

  • 1 cup packed light brown sugar

  • 2 tablespoons fresh lemon juice

  • 1 teaspoon lemon zest

  • ½ teaspoon kosher salt

  • 1 large egg

  • 1 large egg yolk

  • 1 teaspoon vanilla extract

  • 2 cups all-purpose flour

  • 1 cup fresh blueberries

For the Lemon Glaze:

  • cup powdered sugar, sifted

  • 4 teaspoons fresh lemon juice


  1. 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.

  2. 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.

  3. 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.

  4. 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.

  5. To make the glaze: Whisk powdered sugar and lemon juice together in a small bowl until smooth. Drizzle over the blondies. Slice and serve.
