Line an 8” square baking dish with parchment paper and spray it with cooking spray to ensure the brownies lift out easily.
Preheat the oven to 350 degrees Fahrenheit.
Using a hand mixer, combine the cake mix, lemon pudding, lemon juice, eggs, and lemon zest in a medium-sized mixing bowl.
Pour the batter into the prepared pan and spread it evenly.
Bake for 22-24 minutes or until a toothpick inserted in the center comes out clean or with only crumbs (no wet batter).
Remove from the oven and let it cool in the pan for 10 minutes.
Lift the parchment paper out of the pan and allow the brownies to cool completely.
Cut the cooled brownies into squares and prepare the glaze.
For the glaze, combine the powdered sugar and lemon juice together in a bowl until smooth.
Drizzle the glaze over the brownies and sprinkle with lemon zest for garnish.
Enjoy your delightful lemon brownies with lemon glaze!
