Equipment
- 9x13 inch baking pan
- Heatproof bowl
- Saucepan
- Medium bowls
- Whisk
Ingredients
For the Brownie Base
- 3/4 cup salted butter (or unsalted butter with a pinch of salt)
- 6 ounces white chocolate chopped; good quality bar or baking chunks, not chips
- 1 1/2 cups granulated sugar
- 2 large eggs
- 2 tsp vanilla extract
- 1 tsp fresh lemon zest
- 2 1/2 cups all-purpose flour
- 1/4 tsp salt
- 1/2 tsp baking powder
For the Lemon Layer
- 4 large eggs
- 1 1/3 cups granulated sugar
- 1 tsp fresh lemon zest
- 2/3 cup fresh lemon juice freshly squeezed is always best
- 1/4 cup all-purpose flour
For Garnish
- Powdered sugar for dusting
Instructions
- Step 1: Prepare Oven and Pan. Preheat your oven to 350°F (175°C). Generously grease a 9x13-inch baking pan and dust it lightly with flour. This helps ensure your brownies pop out easily.
- Step 2: Make Brownie Batter. In a heatproof bowl, melt butter and chopped white chocolate together by setting the bowl over a saucepan of simmering water (ensuring the bowl does not touch the water), stirring gently until smooth. Once melted, remove from heat.Stir in 1 ½ cups granulated sugar until well combined. Whisk in 2 large eggs, one at a time, until incorporated, then whisk in 2 teaspoons vanilla extract and 1 teaspoon fresh lemon zest.In a separate medium bowl, whisk together 2 ½ cups all-purpose flour, ¼ teaspoon salt, and ½ teaspoon baking powder. Gradually add these dry ingredients to your wet mixture, mixing gently until just combined. Do not overmix. Spread the batter evenly into your prepared pan.
- Step 3: Make Lemon Layer. In a medium bowl, whisk together 4 large eggs and 1 ⅓ cups granulated sugar until the mixture is light, fluffy, and pale yellow. Stir in the remaining 1 teaspoon fresh lemon zest and ⅔ cup fresh lemon juice. Finally, gradually whisk in ¼ cup all-purpose flour until the mixture is completely smooth.
- Step 4: Assemble and Bake. Carefully pour the lemon mixture evenly over the brownie batter in the pan. Pop the pan into your preheated oven and bake for 30-35 minutes. It's done when the edges look nicely set, and a toothpick inserted into the center of the lemon layer comes out with moist crumbs.
- Step 5: Cool and Serve. Let these brownies cool completely in the pan before slicing. This can take a couple of hours, or you can speed it up in the fridge. Once completely cool, slice them into bars. For a final elegant touch, dust them with a little powdered sugar right before serving. Enjoy!
Notes
Tips for Success: Don't overbake; the lemon layer should be set but still have a slight jiggle in the very center. Always use fresh lemon juice and zest for the best, brightest lemon flavor. Cool completely before cutting for clean slices; chilling overnight is highly recommended. Use room temperature eggs for both layers to help them incorporate smoothly into the batter. You can prep the brownie batter and lemon layer mixes separately and store them covered in the fridge for up to 24 hours; bring to room temperature before assembling and baking.
Storage: Store in an airtight container at room temperature for up to 2 days (if your kitchen isn't too warm), or in the refrigerator for up to 5 days. For longer storage, wrap individual bars tightly in plastic wrap and place in a freezer-safe bag or container; they'll keep well for up to 1-2 months. Thaw in the refrigerator overnight or at room temperature for a few hours before serving.
Substitutions & Additions: Not a white chocolate fan? Try using semi-sweet or dark chocolate chips for the brownie base. For an even more intense citrus kick, add another ½ teaspoon of lemon zest to either the brownie or lemon layer. Scatter a handful of fresh or frozen (not thawed) raspberries or blueberries over the brownie batter before pouring the lemon layer. A sprinkle of shredded coconut in the brownie batter adds lovely texture and flavor. Instead of (or in addition to) powdered sugar, drizzle a simple lemon glaze (powdered sugar whisked with a little lemon juice) over the cooled bars.
