Equipment

  • 8x8 inch (20x20 cm) pan

Ingredients

Lemon Brownies

  • ½ cup unsalted butter (112 grams)
  • 3 oz white chocolate (85 grams)
  • ¾ cup granulated sugar (150 grams)
  • 2 large eggs room temperature
  • 2 tbsp lemon zest
  • 3 tbsp lemon juice (45 ml) freshly squeezed
  • 1 ¼ cup all purpose flour (156 grams)
  • ¼ teaspoon salt

Lemon Glaze

  • 1-2 tbsp fresh lemon juice (15-30 ml)
  • 1 ½ - 2 ½ cups powdered sugar (165-275 grams)

Instructions

Lemon Brownies

  • Preheat the oven to 325F degrees. Line an 8x8 inch pan with parchment paper or aluminium foil, leaving an overhang around the edges. Alternatively, lightly grease the pan.
  • Chop the chocolate very finely and place in a heatproof bowl along with the butter. Microwave for 45-second intervals on medium power (not high power, which is often standard). Remove from the microwave between each interval and stir. Repeat the process until smooth.
  • Whisk the sugar, eggs, vanilla, lemon zest and lemon juice into the butter and chocolate mixture until no lumps remain.
  • Whisk in the flour and salt. Be sure to stop mixing as soon as everything is combined.
  • Pour the batter into the prepared pan and smooth the top.
  • Bake in the middle of the preheated oven for 22-25 minutes, or until the top looks set and an inserted toothpick comes out clean or with a few damp crumbs.
  • Cool the bars in the pan.

Lemon Glaze

  • Whisk together 1 tablespoon lemon juice and 1 cup powdered sugar.
  • Continue to whisk in a little more powdered sugar at a time until the glaze is opaque but still thin enough to drizzle.
  • Drizzle the glaze over the cooled lemon brownies and spread into a smooth layer. Before adding the glaze, I lift the bars out of the pan using the overhang of the parchment paper and place on a cutting board.

Notes

  2. Storage: Store in an airtight container at room temperature for up to 4 days, or in the fridge for up to 6 days. 
  3. Nutrition: Details provided are an estimate only and based on 1 brownie with glaze, assuming that pan is sliced into 9 uniform brownies.
