Introduction

Lemon Blueberry Bars are a delightful combination of tangy citrus and sweet berries nestled on a buttery graham cracker crust. This refreshing treat is perfect for summer gatherings or anytime you crave a bright, fruity dessert.

The image shows a stack of three square lemon blueberry dessert bars on a white marbled surface. Each bar has two layers: a thick, crumbly golden brown crust at the bottom and a pale yellow creamy lemon layer on top, studded with whole blueberries that are dark blue with hints of purple. The bars have a slightly glossy and smooth texture on the lemon layer, with some powdered sugar dusted lightly on top. To the left, there is a wedge of lemon, bright yellow with glistening juicy pulp. A silver fork is placed in the foreground near the dessert bars. The overall scene is bright and fresh, with the dessert bars as the clear focus. photo taken with an iphone --ar 4:5 --v 7

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 (175°C) and lightly coat an 8×8-inch baking pan with nonstick spray.
Step 2: In a bowl, combine graham cracker crumbs, granulated sugar, and 2 teaspoons lemon zest. Stir in the melted butter until well mixed. Press the mixture evenly into the bottom of the prepared pan.
Step 3: Bake the crust for 10-13 minutes until it is set and lightly golden. Remove from the oven and allow it to cool slightly.
Step 4: 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 to combine.
Step 5: Gently fold the fresh blueberries into the lemon filling mixture.
Step 6: Pour the filling over the baked crust and spread evenly. Return the pan to the oven and bake for about 15 minutes, or until the filling is just set.
Step 7: Allow the bars to cool to room temperature, then refrigerate overnight to fully set.
Step 8: Before serving, dust the top with powdered sugar and cut into squares.

Tips & Variations

For extra zest, add a bit more lemon zest to the filling or sprinkle some on top before baking.
Try substituting fresh blueberries with raspberries or blackberries for different berry flavors.
Use gluten-free graham cracker crumbs to make this recipe gluten-free.

Storage

Store the lemon blueberry bars in an airtight container in the refrigerator for up to 4 days. They taste best chilled and can be eaten cold or brought to room temperature. For best texture, avoid freezing as it may affect the filling’s creaminess.

How to Serve

The middle layer is a pale yellow lemon filling with a smooth and creamy texture. The top layer contains whole blueberries embedded in the lemon filling, dusted lightly with powdered sugar, giving a soft white contrast to the blue and yellow. A silver fork holds a small bite of the dessert in the foreground. A wedge of lemon is placed on the plate’s edge. The plate sits on a white marbled surface. photo taken with an iphone --ar 4:5 --v 7

FAQs

Can I use frozen blueberries instead of fresh?

It’s best to use fresh blueberries for this recipe to prevent excess moisture from affecting the filling. If using frozen berries, thaw and drain them well before folding into the filling.

How can I make the bars less sweet?

You can reduce the sweetness slightly by using less sweetened condensed milk or adding a small amount of fresh lemon juice to balance the sweetness. Keep in mind that the filling relies on the condensed milk for structure and creaminess.
