1-First Step: Prep the pan and oven Preheat your oven to 350ºF. Line an 8×8 or 9×9 inch glass baking pan with parchment paper so the brownies lift out easily after baking. This step matters because the glaze and soft texture can make the brownies stick if the pan is not prepared well.

2-Second Step: Mix the wet ingredients In a medium bowl, whisk together the 2 large eggs, 1/2 cup melted unsalted butter, and 1 teaspoon vanilla extract. Whisk just until the mixture looks smooth and blended. If you are using an electric mixer, keep it on low speed so the batter stays tender.

3-Third Step: Add the dry ingredients Pour in the 15.25 oz box of strawberry cake mix and the 1/2 teaspoon salt. Stir until the batter becomes thick and fully combined. It will look dense, and that is exactly what you want for these strawberry brownies.

4-Fourth Step: Spread the batter Transfer the batter to the prepared pan and spread it evenly into the corners. Use a spatula to smooth the top so the brownies bake in an even layer. If you want to add chocolate chips, sprinkles, or freeze-dried strawberries, fold them in gently before spreading the batter.

5-Fifth Step: Bake until just set Bake for 20 to 25 minutes at 350ºF. The edges should look set, and the center should be puffy. Since ovens vary, start checking near the 20-minute mark. A toothpick inserted in the center should come out with a few moist crumbs, not wet batter.

6-Sixth Step: Cool completely Let the brownies cool completely in the pan before adding the glaze. This helps the top stay smooth instead of melting into the warm surface. Cooling also makes slicing easier later.

7-Seventh Step: Make the glaze In a small bowl, mix 3/4 cup powdered sugar, 2 tablespoons strawberry preserves or jelly, and 1 tablespoon milk until smooth. If the glaze seems too thick, add a tiny splash more milk. If it is too thin, add a bit more powdered sugar.

8-Eighth Step: Finish and set Spread the glaze over the cooled brownies with a spoon or offset spatula. Let the glaze set for a few hours before cutting. This extra wait helps the squares stay neat and keeps the glaze from smearing.

9-Final Step: Slice and serve Lift the brownies out using the parchment paper, place them on a cutting board, and slice into squares. Serve them as-is or top with fresh strawberries for a pretty finish. These brownies are soft, sweet, and perfect for a quick dessert tray.
