Step 1: Prepare the Pan

Preheat oven to 350°F (175°C). Line an 8×8-inch baking pan with parchment paper, leaving overhang for easy removal. Lightly spray with nonstick spray.

Step 2: Make the Brownie Batter

In a large mixing bowl, add the strawberry cake mix, eggs, and vegetable oil (or melted butter). Mix until fully combined and thick. Fold in the white chocolate chips until evenly distributed.

Step 3: Bake

Spread the thick batter evenly into the prepared pan, smoothing the top with a spatula. Bake for 23–28 minutes, or until the edges are set and a toothpick inserted in the center comes out with a few moist crumbs (not wet batter).

Step 4: Cool Completely

Remove brownies from the oven and allow them to cool completely in the pan before glazing. This ensures clean slices and a smooth glaze finish.

Step 5: Prepare the Glaze

In a small bowl, whisk together the powdered sugar, strawberry preserve, and heavy cream (or milk) until smooth and pourable. Adjust consistency if needed by adding a few drops of milk.

Step 6: Glaze the Brownies

Pour the glaze over the cooled brownies and gently spread it into an even layer. Let the glaze set for 20–30 minutes before slicing.
