In a large bowl, stir together the strawberry cake mix, melted butter, eggs, vanilla, and salt until a thick batter forms with no dry streaks.

Fold in the white chocolate chips. Scrape the batter into the prepared pan and press it into an even layer with a spatula.

Bake for 20-22 minutes, until the edges are set and a toothpick inserted near the center comes out with a few moist crumbs. Do not overbake.

Let the brownies cool fully in the pan on a wire rack before adding the glaze. Warm brownies will melt the topping.

Whisk powdered sugar, crushed freeze-dried strawberries, 2 tablespoons milk, and salt until thick but spreadable. Add more milk by the teaspoon if needed. Spread over the cooled brownies, sprinkle with extra strawberry crumbs if using, let set, then slice into 16 squares.
