01 - Preheat oven to 350°F. Line an 8x8-inch baking pan with parchment paper, allowing overhang for easy removal.

03 - Beat in eggs, vanilla extract, lemon zest, and lemon juice until fully incorporated.
04 - Stir in flour, baking powder, and salt until just incorporated. Avoid overmixing to prevent tough texture.
05 - Gently fold diced strawberries into the batter until evenly distributed.
06 - Spread batter evenly in prepared pan. Bake for 28-32 minutes until top is set and toothpick inserted in center comes out with moist crumbs.
07 - Allow blondies to cool completely in the pan on a wire rack before glazing.
08 - Whisk powdered sugar with lemon juice until smooth and pourable consistency is achieved.
09 - Drizzle glaze evenly over cooled blondies. Let set for 15 minutes, then cut into squares and serve.
