How to Make Lemon Blueberry Bars Recipe

Step 1: Preheat and Prepare Pan

Preheat your oven to 350°F (175°C). Line a baking dish with parchment paper, leaving some overhang for easy removal later. Lightly grease if needed to prevent sticking.

Step 2: Make the Crust

In a bowl, combine flour, sugar, and melted or softened butter. Mix until a crumbly dough forms. Press the mixture evenly into the bottom of the prepared pan, making sure it’s compact and level.

Step 3: Pre-Bake the Crust

Bake the crust for about 15–18 minutes, or until it is lightly golden. Remove from the oven and let it cool slightly while preparing the filling.

Step 4: Prepare the Filling

In another bowl, whisk together eggs, sugar, lemon juice, lemon zest, flour, baking powder, and a pinch of salt until smooth. The mixture should be well combined and slightly thick.

Step 5: Add Blueberries

Gently fold the blueberries into the filling, being careful not to crush them. This helps keep their shape and distributes them evenly throughout the bars.

Step 6: Assemble and Bake

Pour the filling over the pre-baked crust and spread evenly. Bake for 20–25 minutes, or until the center is set and no longer jiggly.

Step 7: Cool and Slice

Allow the bars to cool completely at room temperature, then refrigerate for at least 1–2 hours for clean slicing. Once chilled, lift out using parchment paper and cut into squares.

Pro Tips

Use Fresh Lemon Juice:
Fresh juice provides the best bright and tangy flavor.

Don’t Overbake:
Remove when the center is just set to keep the bars soft and tender.

Chill Before Cutting:
Helps the bars firm up and makes slicing cleaner.

Toss Blueberries Lightly in Flour:
Prevents them from sinking in the batter.

How to Serve

Dessert Treat:
Serve chilled or at room temperature for a refreshing dessert.

With Toppings:
Dust with powdered sugar or add whipped cream for extra sweetness.

Party Dessert:
Perfect for sharing at gatherings, picnics, or celebrations.

Storage

Refrigerator:
Store in an airtight container for up to 4–5 days.

Reheating:
Not required—best served chilled or at room temperature.

Freezing:
Freeze for up to 2 months and thaw before serving.
