Turn your oven to 350°F (175°C). Line an 8x8 inch baking tin with parchment paper, and let the edges hang over the sides so you can easily lift out the dessert later.
02 -
Combine the flour, white sugar, salt, and baking powder in a medium-sized mixing bowl, giving it a good stir.
03 -
Grab a large bowl and beat the softened butter with an electric mixer until it’s smooth. Drop in one egg, beat it in, then add the next egg. Once both are mixed, fold in the lemon juice and zest until blended.
04 -
Slowly add the dry mixture to your bowl of wet ingredients, using the mixer on a low setting. Stop mixing as soon as it comes together to keep the batter soft – overmixing’s not your friend here.
05 -
Pour the mixture into your prepped pan. Smooth out the top if you need to. Bake for 22 to 25 minutes, just until the edges look lightly browned and set. A toothpick should come out clean or with a tiny bit of batter – keep an eye on it to avoid overbaking.
06 -
While waiting for the brownies to cool, mix powdered sugar and lemon juice in a small bowl. Add more juice or sugar to get the thick-but-pourable texture you like.
07 -
Once the dessert is fully cool in the tin, pour the glaze evenly over the top. Spread it around, and if you want, sprinkle some extra zest on there.

When the topping has set, use the parchment paper to lift the baked treat out. Cut into squares or rectangles and dig in.
