Ingredients

Brownies:

  • 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

Instructions

  1. Prepare the pan: Preheat your oven to 350°F (175°C). Line an 8×8-inch light-colored aluminized steel baking pan with parchment paper, ensuring an overhang for easy removal, and set it aside.
  2. Melt butter and chocolate: In a microwave-safe bowl, combine the butter and white chocolate. Microwave initially for 1 minute covered with a paper towel to prevent splatter. Stir well, then continue microwaving in 15-30 second increments, stirring between each, until the mixture is smooth and fully melted but not overheated. Remove from microwave and let it cool slightly.
  3. Create lemon sugar: In a large mixing bowl, combine the granulated sugar and lemon zest. Rub the mixture between your fingertips to release the lemon oils and infuse the sugar with lemon flavor, enhancing the overall aroma and taste.
  4. Add eggs and extracts: Add the two eggs, egg yolk, lemon extract, and vanilla extract to the lemon sugar mixture. Whisk vigorously for about one minute to combine and lighten the batter.
  5. Mix with butter mixture: Pour the cooled white chocolate and butter mixture into the egg mixture. Gently fold together until fully combined, ensuring not to deflate the batter.
  6. Add remaining dry ingredients: Sift in the all-purpose flour, salt, and baking powder. Fold gently a few times to incorporate, then fold in the fresh lemon juice last to maintain the bright lemon flavor.
  7. Combine ingredients: Continue folding until the batter is just incorporated, being careful not to overmix which could toughen the brownies. Optionally, fold in white chocolate chips for added texture and richness.
  8. Pour into pan: Transfer the batter evenly into the prepared baking pan, smoothing the top with a spatula for an even surface.
  9. Bake: Bake in the preheated oven for approximately 25–30 minutes. The edges should be golden brown while the top remains pale. Test doneness by inserting a toothpick in the center; it should come out mostly clean with a few moist crumbs. Avoid overbaking to keep the brownies fudgy. Remove from oven and cool completely in the pan.
  10. Make the glaze: In a small bowl, whisk together powdered sugar and fresh lemon juice until the glaze is thick yet pourable, perfect for spreading.
  11. Spread over brownies: Using an offset spatula, spread the lemon glaze evenly over the cooled brownies.
  12. Garnish and set: Optional—sprinkle additional lemon zest on top for decoration. Allow glaze to set for 15–30 minutes before slicing into 9 squares. Store at room temperature for 2–3 days or enjoy chilled for a refreshing treat.

Notes

  • Use light-colored aluminized steel pans to prevent over-browning the edges.
  • Rub lemon zest into sugar to maximize lemon aroma and flavor in the batter.
  • Room temperature eggs help achieve a smooth, homogenous batter.
  • Be careful not to overbake; a few moist crumbs on a toothpick are ideal for fudgy brownies.
  • The brownies can be stored at room temperature or enjoyed cold from the refrigerator.
  • Optional: add white chocolate chips during mixing for extra texture.
