Step-by-Step Instructions
Preparing the Perfect Strawberry Base

- Hull strawberries and dice into ½-inch pieces, maintaining uniform size for even distribution and consistent baking throughout bars.
- Toss diced strawberries with 2 tablespoons granulated sugar and 1 tablespoon lemon juice, allowing to macerate for 15 minutes.
- Drain excess liquid from macerated strawberries, reserving juice for glaze if desired, and toss fruit with 1 tablespoon cornstarch.
- Set prepared strawberries aside while preparing blondie base, ensuring they remain at room temperature for proper incorporation.
- For enhanced flavor, consider adding 1 tablespoon strawberry jam to intensify berry taste and create beautiful color swirls.
Creating the Lemon-Infused Blondie Base
- Preheat oven to 350°F and line 9×13-inch baking pan with parchment paper, leaving overhang for easy removal.
- Melt 1 cup unsalted butter in microwave or saucepan, allowing to cool slightly while maintaining liquid consistency for proper mixing.
- In large mixing bowl, whisk melted butter with 1½ cups packed brown sugar until smooth and well combined.
- Add 2 large eggs one at a time, beating well after each addition, then mix in 2 teaspoons vanilla extract.
- Zest 2 large lemons directly into mixture, then add 3 tablespoons fresh lemon juice, whisking until evenly distributed.
- In separate bowl, whisk together 2 cups all-purpose flour, 1 teaspoon baking powder, and ½ teaspoon salt.
Mastering the Mixing Technique
- Add dry ingredients to wet ingredients gradually, mixing just until flour disappears to prevent tough texture from overmixing.
- Fold in prepared strawberries gently but thoroughly, ensuring even distribution without breaking fruit pieces or overworking batter.
- For extra lemon intensity, add ½ teaspoon lemon extract or 1 tablespoon lemon curd for enhanced flavor complexity.
- Spread batter evenly in prepared pan using offset spatula, creating smooth surface for professional appearance.
- Gently tap pan on counter to release air bubbles and ensure even distribution of batter and fruit pieces.
- Optional: Sprinkle top with additional diced strawberries or lemon zest for enhanced visual appeal and flavor concentration.
Achieving Perfect Baking Results
- Bake for 25-30 minutes until edges are set and lightly golden, and center springs back when gently touched.
- Avoid overbaking, which creates dry texture—bars should be just set with slight give in center for optimal chewiness.
- Cool completely in pan on wire rack before cutting, allowing structure to set properly for clean, even squares.
- For enhanced presentation, dust with powdered sugar or drizzle with simple lemon glaze while still warm.
- Cut into 24 squares using sharp knife, wiping blade clean between cuts for professional appearance.
- Store covered at room temperature for up to 3 days, or refrigerate for extended storage while maintaining texture.
Creating Optional Lemon Glaze

- Adjust consistency with additional powdered sugar or lemon juice to achieve perfect drizzling texture.
- Drizzle over cooled bars in decorative pattern, allowing some glaze to pool for visual interest.
- Allow glaze to set for 15 minutes before cutting to prevent smearing and maintain clean presentation.
- For variation, add food coloring to create pastel yellow glaze that enhances visual appeal beautifully.
- Store glazed bars covered to prevent glaze from drying out while maintaining optimal texture and appearance.
Perfect Storage and Serving
- Store bars in covered container at room temperature for optimal texture, separating layers with parchment paper.
- For longer storage, refrigerate up to 1 week or freeze up to 3 months, wrapping individually for convenience.
- Serve at room temperature for best texture and flavor development, allowing refrigerated bars to come to temperature.
- Cut fresh garnishes just before serving to maintain vibrant appearance and prevent wilting during display.

Frequently Asked Questions
Can I use frozen strawberries instead of fresh?
While fresh strawberries provide the best texture and flavor, you can use frozen strawberries if fresh aren’t available. Thaw them completely and drain excess liquid thoroughly before macerating with sugar. You may need to add an extra tablespoon of cornstarch to absorb additional moisture and prevent soggy bars.
How do I prevent the bars from being too wet or soggy?
The key is properly preparing your strawberries by macerating them with sugar, draining excess liquid, and tossing with cornstarch. Also, avoid overbaking which can cause moisture to redistribute unevenly. Make sure your strawberries are diced uniformly and not overripe, which contains more water.
What’s the best way to get clean, professional-looking cuts?
Allow bars to cool completely before cutting—this is crucial. Use a sharp knife and wipe the blade clean between cuts. Dusting your cutting board with powdered sugar can also prevent sticking. For extra-clean cuts, chill the bars for 30 minutes before cutting.
Can I make these bars ahead of time?
Yes! These bars actually improve in flavor after sitting overnight as the flavors meld together. Store covered at room temperature for up to 3 days, or freeze for up to 3 months. They’re perfect for make-ahead entertaining and actually taste better the next day.
