Ingredients

For the Blondie Base:

  • 2 large eggs room temperature
  • 1 cup 226 grams unsalted butter, melted and slightly cooled
  • ¼ cup fresh-squeezed lemon juice approximately from 2 lemons
  • cups 190 grams plain all-purpose flour
  • 1 cup 200 grams white granulated sugar
  • ½ teaspoon fine salt
  • Finely grated zest of 2 lemons roughly 2 tablespoons

For the Glaze:

  • 1 cup 120 grams sifted confectioners’ sugar
  • 2 tablespoons freshly pressed lemon juice more as needed for desired texture
  • Optional garnish: additional lemon zest finely grated

Instructions

  • Preheat the oven to 350°F (175°C). Prepare an 8x8-inch square baking tin by lining it with parchment paper or lightly greasing the surface to prevent sticking.
  • In a large mixing bowl, combine the melted butter and sugar. Whisk until the mixture turns smooth and slightly glossy. Incorporate the eggs one at a time, mixing thoroughly after each addition. Blend in the lemon juice and zest.
  • Gradually add the flour and salt to the wet mixture. Fold gently using a spatula or spoon until no dry streaks remain, being cautious not to overwork the batter.
  • Transfer the batter into the prepared baking dish, spreading it into an even layer. Bake in the preheated oven for 23 to 28 minutes, or until the edges are lightly golden and a toothpick inserted into the center emerges with moist crumbs.
  • While the blondies are cooling slightly in the pan, whisk together the powdered sugar and lemon juice in a small bowl until smooth and pourable.
  • Drizzle the glaze evenly over the warm blondies, smoothing it toward the corners with a spatula if necessary. Allow the bars to cool completely at room temperature until the glaze sets before cutting into squares.

Notes

For a more pronounced citrus aroma, garnish the glazed bars with a light sprinkle of fresh lemon zest just before serving.
