Introduction

These Lemon Blueberry Bars are a refreshing treat that perfectly balance tart lemon with sweet blueberries. With a buttery graham cracker crust and a smooth, creamy filling, they make for a delightful dessert or snack any time of year.

The image shows a stack of three blueberry lemon bars on a white marbled surface. Each bar has two layers: a thick, crumbly golden-brown crust at the bottom and a smooth, creamy pale yellow lemon filling on top, dotted with whole blueberries that add dark purple spots. The top bar has a dusting of white powdered sugar, giving it a light sparkle. In the foreground, there is a silver fork and a wedge of bright yellow lemon, enhancing the fresh look of the dessert.

Ingredients

1 1/2 cups graham cracker crumbs
3 tablespoons granulated sugar

2 teaspoons lemon zest (for crust)
6 tablespoons unsalted butter (melted)

2 large egg yolks
1 14-ounce can sweetened condensed milk

1/2 cup fresh lemon juice
1 1/2 teaspoons lemon zest (for filling)
1 cup fresh blueberries

Powdered sugar (for dusting)

Instructions

Step 1: Preheat your oven to 350°F. Lightly coat an 8×8-inch baking pan with nonstick spray.
Step 2: In a bowl, mix graham cracker crumbs, granulated sugar, and 2 teaspoons lemon zest. Stir in the melted butter until combined. Press the mixture evenly into the prepared pan and bake for 10-13 minutes until set. Remove and let cool.

Step 3: In a separate bowl, whisk the egg yolks with the sweetened condensed milk until smooth. Add the fresh lemon juice and 1 1/2 teaspoons lemon zest, mixing until fully incorporated. Gently fold in the fresh blueberries.
Step 4: Pour the filling over the cooled crust and bake for about 15 minutes or until the filling is just set.
Step 5: Allow the bars to cool to room temperature, then refrigerate overnight for best texture.

Step 6: Before serving, dust the bars with powdered sugar and cut into squares.

Tips & Variations

For a crunchier crust, toast the graham cracker crumbs lightly before mixing.
Use frozen blueberries if fresh are not available; just thaw and drain excess liquid before folding in.

Try adding a teaspoon of vanilla extract to the filling for extra depth of flavor.
For a tangier twist, increase the lemon juice by a tablespoon, adjusting sugar if needed.

Storage

Store leftover bars in an airtight container in the refrigerator for up to 4 days. They taste best chilled, so reheat is not necessary. If you prefer them slightly warm, let them sit at room temperature for a few minutes before serving.
