Method
Step-by-Step
- Heat the oven to 350°F (175°C). Line an 8-inch square baking pan with parchment paper, leaving enough overhang on two sides to lift out the cooled blondies.
- Melt the butter and let it cool briefly. Whisk the melted butter and granulated sugar together until the mixture looks smooth.
- Whisk in the egg, vanilla extract, finely grated lemon zest, and fresh lemon juice until thoroughly combined.
- In a separate bowl, stir together the flour, baking powder, and salt. Add the dry ingredients to the butter mixture and stir just until no dry streaks remain.
- Gently fold in the finely diced, patted-dry strawberries. Spread the batter evenly in the prepared pan.
- Bake for approximately 28–35 minutes, until the edges are lightly golden and a toothpick inserted near the center comes out with a few moist crumbs.
- Cool the blondies completely in the pan for about 30 minutes. Stir the powdered sugar with 1 1/2 to 2 tablespoons lemon juice and optional lemon zest to make a thick, pourable glaze, then drizzle it over the cooled blondies.
- Allow the glaze to set before slicing. For especially clean cuts, chill the fully cooled and glazed blondies for 20–30 minutes, then lift them out using the parchment overhang.
Notes
Pat the strawberries very dry and dice them small so excess moisture does not make the center gummy. Use fresh lemon zest and juice for the fullest flavor, and avoid overbaking; a few moist crumbs on the toothpick are ideal. Store covered at room temperature for up to 2 days or refrigerated for up to 4 days. Bring refrigerated blondies to room temperature before serving.
