Ingredients
  

For the Lemon Brownie Base:

  • cups 150 g all-purpose flour
  • 2 tbsp 14 g cornstarch
  • ½ tsp salt
  • cups 250 g white granulated sugar
  • 2 tbsp fresh lemon zest
  • ¾ cup 170 g melted unsalted butter (slightly warm)
  • 1 tbsp 13 g vegetable oil
  • 2 large eggs room temperature
  • 3 tbsp 42 g freshly squeezed lemon juice
  • ½ tsp vanilla extract

For the Lemon Glaze:

  • 1 cup 125 g powdered sugar
  • tbsp 22 g freshly squeezed lemon juice

Instructions
 

  • Prep Your Baking Pan: Preheat your oven to 180°C (350°F). Grease and line an 8x8-inch baking pan with parchment paper, leaving extra paper for easy removal later.
  • Combine Dry Ingredients: Sift together flour, cornstarch, and salt in a bowl. Whisk well and set aside.
  • Infuse Sugar with Lemon Zest: In a large mixing bowl, rub lemon zest into granulated sugar to release its oils, creating a fragrant, citrusy sugar mixture.
  • Create the Wet Mixture: Add melted butter, vegetable oil, eggs, lemon juice, and vanilla to the sugar mixture. Whisk until smooth but don’t overmix.
  • Combine Wet and Dry Ingredients: Gradually fold the dry ingredients into the wet mixture, mixing just until combined to avoid overworking the batter.
  • Bake: Pour the batter into the prepared pan and smooth the top. Bake for 22–25 minutes or until a toothpick inserted comes out with a few moist crumbs.
  • Cool Completely: Let the brownies cool in the pan for 1–2 hours before lifting them out using the parchment paper.
  • Make the Glaze: Mix powdered sugar and lemon juice in a small bowl until smooth and spreadable.
  • Glaze and Set: Spread the glaze over the cooled brownies. Let it set for 30 minutes to an hour before slicing and serving.
