Ingredients

Scale

Brownie

  • 1/2 cup unsalted butter
  • 1 (4 oz) white chocolate bar (Ghirardelli recommended)
  • 3/4 cup granulated sugar
  • 2 Tbsp lemon zest (from about 2 large lemons)
  • 2 large eggs (room temperature)
  • 1 large egg yolk (room temperature)
  • 1 tsp lemon extract
  • 1 tsp vanilla extract
  • 1 cup + 2 Tbsp all-purpose flour (spooned and leveled)
  • 1/2 tsp salt
  • 1/8 tsp baking powder
  • 2 Tbsp fresh lemon juice

Lemon Glaze

  • 1 cup powdered sugar
  • 2 Tbsp fresh lemon juice
  • Lemon zest (optional, for garnish)

Instructions

  1. Prepare the pan: Preheat the oven to 350°F. Line an 8×8 inch light-colored aluminized steel baking pan with parchment paper, allowing some overhang for easy removal later. Set aside.
  2. Melt butter and chocolate: Combine the butter and white chocolate in a microwave-safe bowl. Microwave covered with a paper towel to avoid splatter for 1 minute, then stir. Continue microwaving in 15 to 30-second increments, stirring each time until the mixture is fully melted, smooth, and glossy but not burnt. Remove and let cool slightly.
  3. Create lemon sugar: In a large mixing bowl, combine the granulated sugar and lemon zest. Rub them between your fingers to release the oils from the zest, infusing the sugar with bright lemon flavor.
  4. Add eggs and extracts: Into the lemon sugar, add the eggs, egg yolk, lemon extract, and vanilla extract. Whisk vigorously for about 1 minute until fully combined and slightly frothy.
  5. Mix with butter mixture: Pour the slightly cooled white chocolate and butter mixture into the egg mixture. Gently fold together until just combined, being careful not to deflate the batter.
  6. Add dry ingredients and lemon juice: Sift or add the all-purpose flour, salt, and baking powder into the wet ingredients. Fold gently a few times to incorporate. Finally, add the fresh lemon juice and fold to combine thoroughly but without overmixing. Optionally, fold in white chocolate chips for extra texture.
  7. Pour into pan: Transfer the batter evenly into the prepared baking pan, spreading it out smoothly with a spatula.
  8. Bake: Place the pan in the preheated oven and bake for 25 to 30 minutes. The edges should be golden brown while the center remains moist; a toothpick inserted in the center should come out with a few moist crumbs but no wet batter.
  9. Cool completely: Remove the brownies from the oven and allow them to cool completely in the pan on a wire rack. This will make glazing easier.
  10. Make the glaze: In a small bowl, whisk together the powdered sugar and fresh lemon juice until smooth and thick but pourable.
  11. Spread over brownies: Using an offset spatula, carefully spread the lemon glaze evenly over the cooled brownies.
  12. Garnish and set: Optionally sprinkle additional lemon zest on top for extra color and aroma. Allow the glaze to set for 15 to 30 minutes before slicing into 9 squares and serving. Store at room temperature for up to 3 days or refrigerate for a denser texture.

Notes

  • Use room temperature eggs for better mixing and texture.
  • Do not overbake; brownies should remain moist inside with slightly firm edges.
  • The lemon sugar step is essential to infuse strong lemon flavor.
  • White chocolate chips can be added for added chocolate bursts if desired.
  • Store brownies in an airtight container; they taste excellent chilled as well.
