01 - Preheat your oven to 350°F. Line an 8x8-inch baking pan with parchment paper, allowing some overhang for easy removal later.
02 - In a small bowl, mash the diced strawberries with a fork until juicy but still retaining some chunky texture. Set aside.
03 - In a large bowl, whisk together the melted butter and granulated sugar until thoroughly combined. Add the eggs and vanilla extract, whisking until the mixture is smooth and glossy.
04 - Sift the flour, cocoa powder, and salt into the wet mixture. Fold gently using a spatula until just combined—take care not to overmix as this can affect the brownie texture.
05 - Fold the mashed strawberries into the batter, distributing them evenly throughout.
06 - Transfer the batter to the prepared pan, using a spatula to smooth the top into an even layer.
07 - Bake for 28 to 32 minutes, or until a toothpick inserted into the center emerges with a few moist crumbs clinging to it.
08 - Allow the brownies to cool completely in the pan before removing or adding the glaze.
09 - Puree the remaining strawberries until smooth. Whisk together with the powdered sugar and lemon juice until you achieve a smooth, drizzleable consistency.
10 - Drizzle the glaze over the cooled brownies. Cut into squares and serve.
