01 - Preheat oven to 350°F. Line an 8x8-inch baking pan with parchment paper, leaving an overhang for easy removal.
02 - In a large bowl, whisk together melted butter, granulated sugar, and brown sugar until smooth. Add eggs, vanilla extract, lemon zest, and lemon juice. Whisk until fully combined.
03 - Stir in flour, baking powder, and salt until just incorporated. Do not overmix.
04 - Gently fold in diced strawberries.
05 - Spread the batter evenly in the prepared pan. Bake for 28-32 minutes, or until the top is set and a toothpick inserted in the center comes out with a few moist crumbs.
06 - Cool completely in the pan on a wire rack. For the glaze, whisk powdered sugar with lemon juice until smooth and pourable. Drizzle glaze evenly over cooled blondies. Let set for 15 minutes, then cut into squares and serve.
