Step-by-Step Instructions

• Preheat oven to 350°F (175°C) and prepare an 8×8-inch baking pan with parchment paper or grease it.
• Cream softened butter and granulated sugar together until pale and fluffy using an electric mixer.
• Add the eggs one at a time, mixing well after each addition, then stir in lemon juice and lemon zest.
• In a separate bowl, whisk together flour, baking powder, and salt, then add to the wet mixture until just combined.
• Pour batter into prepared pan and bake for 20–25 minutes until edges set and a toothpick comes out with a few moist crumbs.
• Allow brownies to cool in the pan for 10 minutes, then prepare the glaze by mixing powdered sugar, lemon juice, and zest until smooth.
• Pour the glaze over warm brownies, let it seep in, cool completely, then slice into squares and serve.
