Spread into your prepared baking dish and even it out. Bake for 25-30 minutes or until a toothpick in center comes out clean.
Cool 20 minutes. Then remove the brownies, using your parchment paper, or just cool in the pan, on a cooling rack.
Lemon Glaze
While the brownies are cooling, make your glaze.
Whisk powdered sugar to get rid of any clumps, then mix in your lemon juice and a tablespoon of zest. If you want the glaze thicker, add more powdered sugar or for a thinner glaze, add more lemon juice.
