Lemon Brownies are dessert bars that are dense and moist with a lemony flavor and topped with a sweet glaze.
Preheat oven to 350°F and prepare a 9x9-inch pan by lining it with parchment paper (or lightly grease and flour). (You could use a 9x13-inch pan for more servings, but the bars will be thinner.)
In a large bowl, combine the melted butter and brown sugar. Stir well.
Spread the batter evenly into the prepared pan. Bake 35-45 minutes, or until the edges are turning golden brown. (If you are using a 9x13-inch pan, bake for 25-30 minutes.)
Allow brownies to cool before glazing.
In a medium bowl, combine the confectioners' sugar and water and whisk until smooth.
Pour the glaze over the cooled brownies and serve.
