01 - Preheat oven to 350°F. Line an 8x8-inch baking pan with parchment paper, allowing overhang for easy removal.
02 - Mash the diced strawberries with a fork in a small bowl until juicy but retaining some chunks. Set aside.
03 - Whisk melted butter and sugar in a large bowl until well blended. Add eggs and vanilla, whisking until smooth.
04 - Sift flour, cocoa powder, and salt into the wet mixture. Fold gently until just combined, avoiding overmixing.
05 - Fold the mashed strawberries into the batter until evenly distributed.
06 - Pour batter into the prepared pan, smoothing the surface with a spatula.
07 - Bake for 28 to 32 minutes, until a toothpick inserted in the center emerges with moist crumbs.
08 - Allow brownies to cool thoroughly in the pan before glazing.
09 - Puree the strawberries. Whisk together with powdered sugar and lemon juice until smooth.
10 - Drizzle glaze over cooled brownies. Cut into squares and serve.
