Follow these simple steps to create the Best Lemon Brownies:

1. Preheat the Oven: Begin by preheating your oven to 350°F (175°C). Grease and line a 9×13 inch baking pan with parchment paper.

2. Mix Wet Ingredients: In a large bowl, whisk together the melted butter and granulated sugar until well combined.

3. Add Eggs and Flavor: Incorporate the eggs one at a time, whisking well after each addition. Stir in the vanilla extract and lemon zest for added flavor.

4. Combine Lemon Juice: Add the freshly squeezed lemon juice to the wet mixture and stir until smooth. The mixture may look a bit curdled, but that’s perfectly okay.

5. Mix Dry Ingredients: In a separate bowl, whisk together the flour, salt, and baking powder until evenly mixed.

6. Combine Mixtures: Gradually fold the dry ingredients into the wet ingredients using a spatula. Mix until just combined; be careful not to overmix.

7. Pour Batter: Transfer the batter into the prepared baking pan, smoothing the top with a spatula for an even surface.

8. Bake: Place the pan in the preheated oven and bake for 25-30 minutes. The brownies should be set in the middle; a toothpick inserted should come out with a few moist crumbs (but not raw batter).

9. Cool: Allow the brownies to cool in the pan for about 10-15 minutes, then lift them out using the parchment paper and let them cool completely on a wire rack.

10. Dust with Powdered Sugar: Once cool, dust the top with powdered sugar if desired before cutting into squares.
