Follow these simple steps to create delicious, tangy lemon brownies that will be the star of your dessert table:
Preheat your oven to 350°F (175°C). Grease an 8x8-inch baking pan with butter or line it with parchment paper for easy removal of the brownies.
Mix the dry ingredients: In a medium bowl, whisk together the flour, baking powder, and salt. Set aside.
Cream the butter and sugar: In a separate large bowl, beat the softened butter and sugar together until the mixture is smooth and creamy. You can use an electric mixer or do it by hand with a whisk.
Add the eggs and lemon: Add the eggs one at a time, mixing well after each addition. Stir in the fresh lemon juice, lemon zest, and vanilla extract. The lemon zest will bring a fragrant, citrusy aroma to your brownies!
Combine the wet and dry ingredients: Gradually fold the dry ingredients into the wet ingredients, mixing just until combined. Be careful not to overmix, as this can lead to dense brownies.
Bake: Pour the batter into your prepared baking pan and smooth the top with a spatula. Bake for 20-25 minutes, or until a toothpick inserted into the center comes out clean. The top should look slightly golden.
Cool: Let the brownies cool completely in the pan before cutting them into squares.
