Step 1: Preheat and Prep

Set your oven to 350°F (175°C) so it’s ready when you are.

Line a 9×13 inch baking dish with parchment paper, making sure it extends past the edges for easy removal.

Give the paper a quick spray or grease to keep things from sticking later.

Step 2: Whip Up the Batter

Start by whisking the flour and salt together in a bowl—this ensures the salt is distributed evenly.

In a larger mixing bowl, use a hand mixer or stand mixer to beat together the softened butter and sugar until it’s pale and fluffy—about 3 to 4 minutes.

Crack in the eggs one at a time, mixing well after each addition.

Next, stir in your lemon zest, lemon juice, and vanilla. Your kitchen should start smelling like a citrus grove!

Now, gently fold in the flour mixture just until it’s all combined. Avoid overmixing—you’re going for light and tender, not tough.

Step 3: Bake to Perfection

Pour the batter into your prepared pan and spread it evenly with a spatula.

Bake on the center rack for 25 to 30 minutes, or until the edges start to lightly brown and a toothpick inserted in the center comes out clean.

Let the brownies cool completely in the pan on a wire rack before glazing. (Yes, you have to wait—it’s worth it!)

Step 4: Make the Glaze

In a small bowl, whisk the powdered sugar and lemon juice until smooth. Start with 2 tablespoons of juice and add more if it’s too thick.

Stir in the lemon zest for an extra punch of flavor.

Once the brownies are fully cool, pour the glaze evenly over the top and spread it with a spatula.

Let it sit for about 30 minutes so the glaze sets up nicely before slicing.
