Creating these Lemon Brownies is a straightforward process. Follow these simple steps for delicious results:

1. Preheat your oven to 350°F (175°C). Grease and line a 9×13-inch baking pan with parchment paper.
2. Combine Wet Ingredients: In a large bowl, whisk together the melted butter and granulated sugar until well blended. Add the eggs, lemon zest, lemon juice, and vanilla extract, mixing until smooth.
3. Mix Dry Ingredients: In another bowl, combine flour, baking powder, and salt.
4. Combine Mixtures: Gradually add the dry ingredients into the wet mixture, stirring gently until just combined. Be careful not to overmix!
5. Pour into Pan: Spread the batter evenly into the prepared baking pan, making sure it reaches the corners.
6. Bake: Place the pan in the preheated oven and bake for 25-30 minutes, or until the edges are golden, and a toothpick inserted into the center comes out clean.
7. Cool: Once out of the oven, allow the brownies to cool in the pan for about 15 minutes. Then lift them out using the edges of the parchment paper to cool completely on a wire rack.
8. Dust with Sugar: Once cooled, dust the top with powdered sugar for an elegant finish.
9. Cut and Serve: Cut into squares or rectangles, depending on your preference.

By following these steps, your Lemon Brownies will come out perfectly, combining the tartness of lemon with the sweet, fudgy texture everyone loves!
