Preheat your oven to 350°F (175°C). Grease a 9x9-inch baking dish.
Prepare the brownie mix according to the package instructions. Stir in the chocolate chips.
Pour the brownie batter into the prepared baking dish and spread it out evenly.
Bake for 20-25 minutes, or until a toothpick inserted into the center comes out with a few moist crumbs.
Remove the brownies from the oven and let them cool completely.
In a small bowl, whisk together the powdered sugar, milk, and vanilla extract to make a glaze.
Drizzle the glaze over the cooled brownies.
Top the brownies with sliced strawberries.
Allow the glaze to set for about 10 minutes before serving.
Cut into squares and enjoy!
