Creating the Best Lemon Brownies is an effortless process if you follow these simple steps:

1. Preheat the Oven: Start by preheating your oven to 350°F (175°C). Grease and line a 9×13-inch baking pan with parchment paper for easy removal.
2. Mix Butter and Sugar: In a large bowl, combine the melted butter and granulated sugar. Mix until well blended.
3. Add Eggs: Carefully add the eggs, one at a time, mixing thoroughly after each addition.
4. Incorporate Vanilla and Zest: Stir in the vanilla extract and lemon zest, ensuring even distribution.
5. Mix Lemon Juice: Add the fresh lemon juice to the mixture and stir until well combined.
6. Combine Dry Ingredients: In a separate bowl, whisk together the flour, baking powder, and salt.
7. Combine Mixtures: Gradually add the dry ingredients to the wet mixture and stir until just combined. Avoid over-mixing.
8. Pour the Batter: Pour the batter into the prepared baking pan and spread it evenly.
9. Bake: Place the pan in the preheated oven and bake for 25-30 minutes, or until a toothpick inserted in the center comes out clean.
10. Cool: Once baked, remove the pan from the oven and allow the brownies to cool in the pan for about 20-25 minutes.
11. Slice: After cooling, lift the brownies out of the pan using the parchment paper. Cut them into squares for serving.
12. Dust with Sugar: For an elegant finishing touch, dust the brownies with powdered sugar before serving, if desired.
