Ingredients

For the lemon blondie base:

  • ½ cup of unsalted butter softened to room temperature
  • 1 tablespoon of finely grated lemon zest
  • 3 tablespoons of freshly pressed lemon juice
  • ½ teaspoon of vanilla essence
  • 2 large eggs at ambient temperature
  • ½ teaspoon of fine salt
  • 1 cup of granulated white sugar
  • 1 cup of plain all-purpose flour sifted

For the citrus glaze:

  • 2 tablespoons of freshly squeezed lemon juice
  • 1 cup of confectioners’ sugar sifted

Instructions

  • Preheat your oven to 350°F (180°C). Prepare an 8-inch square baking dish by greasing it with butter or baking spray. For easier removal, line the base and two opposite sides with parchment paper, leaving an overhang for lifting.
  • In a mixing bowl, cream the softened butter with the granulated sugar until the mixture is smooth and uniform.
  • Beat in the eggs, one at a time, stirring just until incorporated. Avoid overmixing to maintain a soft texture.
  • Stir in the lemon zest and vanilla extract, blending gently to combine.
  • Sift together the flour and salt, then gradually fold them into the butter mixture. Mix only until no dry streaks remain.
  • Incorporate the lemon juice, stirring briefly until just combined. Do not overmix.
  • Transfer the batter into the prepared pan, smoothing out the surface evenly with a spatula.
  • Place in the preheated oven and bake for approximately 20 minutes, or until the center is just set. A toothpick inserted should come out with a few moist crumbs.
  • Remove from the oven and allow the pan to cool on a wire rack for 10 to 15 minutes. Drape a clean kitchen towel loosely over the top while cooling to retain moisture. Let cool almost entirely before glazing.
  • Once cooled, run a sharp knife along the unlined edges to loosen the blondies, then lift them from the pan using the parchment paper. Place on a cutting board and slice into squares.

To prepare the glaze:

  • In a medium bowl, whisk together the powdered sugar and lemon juice until smooth and thickened to a pourable consistency.
  • Spread the glaze evenly over the cooled blondies using an offset spatula or the back of a spoon. Optionally, finish with a sprinkle of fresh lemon zest.
  • Allow the glaze to set before cutting and serving. Alternatively, cover the pan with plastic wrap and refrigerate until needed.

Notes

  • Oven Accuracy: Baking times may vary depending on your oven and bakeware. Use an oven thermometer if necessary to ensure accurate temperature.
  • Serving: Best enjoyed at room temperature for maximum lemon flavor and a denser, fudgy crumb.
  • Storage: Store in an airtight container at room temperature for up to 3 days or refrigerate for up to a week. Note that refrigeration may reduce moisture over time.
  • Variations: Enhance the flavor by incorporating other citrus zests such as lime or orange. For an adult twist, mix in a tablespoon of citrus liqueur like limoncello or even tequila. Add berries for a fruity variation like strawberry lemon bars.
