Ingredients

Scale
  • 1 cup all-purpose flour
  • 2 tbsp cornstarch
  • 1/2 tsp salt
  • 1 cup white granulated sugar
  • 2 tbsp fresh lemon zest
  • 1/2 cup warm melted unsalted butter
  • 1/4 cup unflavored vegetable oil
  • 2 large eggs, room temperature
  • 1/4 cup freshly squeezed lemon juice
  • 1 tsp vanilla extract/essence
  • 1 1/2 cups powdered sugar (for glaze)
  • 2 tbsp freshly squeezed lemon juice (for glaze)

Instructions

  1. Preheat your oven to 180°C (350°F) and prepare an 8x8 inch square cake tin.
  2. Sift together the all-purpose flour, cornstarch, and salt in a mixing bowl and set aside.
  3. Rub lemon zest into the white granulated sugar for about 30 seconds until aromatic.
  4. Add warm melted unsalted butter, unflavored vegetable oil, large eggs, freshly squeezed lemon juice, and vanilla extract to the lemon sugar mixture and whisk gently.
  5. Fold the dry mixture into the wet ingredients gently.
  6. Pour the batter into the prepared cake tin and shake gently to distribute evenly.
  7. Bake for about 22 minutes and check for doneness with a toothpick.
  8. Allow the brownies to cool completely in the pan for 1 to 2 hours.
  9. Lift the brownies using parchment paper and place them on a wire rack to cool completely.
  10. To make the zesty lemon glaze, whisk powdered sugar with freshly squeezed lemon juice until smooth.
  11. Spread the glaze over the cooled brownies and let it set for 30 minutes to an hour before slicing.

Notes

  • Use a fine grater for lemon zest to maximize fresh flavor.
  • Don’t overmix to maintain fudgy texture.
  • Check for doneness with a toothpick for moist crumbs.
  • Ensure butter is warm—not hot—when adding to maintain texture.
  • Adjust glaze consistency with powdered sugar or lemon juice as needed.
