Baking Lemon Brownies can be a straightforward process if you follow these steps:

1. Preheat the Oven: Begin by preheating your oven to 350°F (175°C). Grease an 8×8-inch baking pan or line it with parchment paper for easy removal.
2. Mix Wet Ingredients: In a large bowl, whisk the melted butter and granulated sugar together until creamy. Add in the eggs and vanilla extract, mixing until smooth.
3. Incorporate Lemon: Stir in the lemon zest and lemon juice, ensuring you combine thoroughly.
4. Combine Dry Ingredients: In another bowl, whisk together the flour, baking powder, and salt until evenly mixed.
5. Combine Mixtures: Gradually add the dry ingredients to the wet mixture, stirring until just combined. Be careful not to overmix, as that can make the brownies dense.
6. Pour into Pan: Spread the batter evenly into the prepared baking pan, smoothing the top with a spatula.
7. 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 or with a few moist crumbs.
8. Cool: Once baked, remove the brownies from the oven and allow them to cool in the pan for about 20 minutes. Then, transfer to a wire rack to cool completely before cutting into squares.
9. Dust with Powdered Sugar: If desired, dust the top of the cooled brownies with powdered sugar for that extra touch of sweetness and elegance.

These easy steps will guide you in creating these amazing lemon brownies without any hassle.
