Preheat the oven to 350 degrees.
Prepare an 9 by 13-inch baking pan with cooking spray. Set aside.
In a stand mixer fitted with a paddle attachment, pour the strawberry cake mix, eggs, and vegetable oil. Mix until well blended.
Remove the bowl from the stand mixer. Pour the batter in the greased baking pan. Using a wooden spoon spread the batter evenly.
Place on the middle rack in the oven for 30 minutes or until a toothpick or butter knife comes out clean when placed in the center.
Allow the strawberry brownies to cool for at least one hour. While the strawberry brownies cool, prepare the lemon-vanilla glaze.
In a measuring cup using a whisk, mix powdered sugar, lemon juice, and vanilla extract until smooth.
Carefully pour the lemon-vanilla glaze over the entire surface of the cooled strawberry brownies. Slice, and garnish with fresh strawberries. Enjoy!
Yes. To prepare brownies in an 8x8 inch baking dish, simply mix one box of strawberry cake mix with 1/3 cup vegetable oil and two eggs. Cut the lemon-glaze down by mixing one cup of powdered sugar, with two tablespoons lemon juice and 1/4 teaspoon of vanilla extract. The baking time will reduce slightly to 20 minutes at 350 degrees.
