Ingredients

Here’s a breakdown of all the ingredients you’ll need to make these blueberry bars:

For the Crust:

All-Purpose Flour: 1 ½ cups of flour forms the base of your crust, providing the structure for the bars.
Granulated Sugar: ¼ cup of sugar adds just the right level of sweetness to the crust.
Salt: A pinch of salt helps balance the sweetness and enhances the other flavors.
Unsalted Butter: 1/2 cup of softened butter creates a rich, flaky texture.
Egg: 1 large egg binds the ingredients and gives the crust structure.

For the Blueberry Filling:

Fresh Blueberries: 2 cups of fresh blueberries provide the bulk of the filling and a beautiful pop of color.
Granulated Sugar: ½ cup of sugar helps sweeten the blueberries and draw out their juice.
Cornstarch: 2 tablespoons of cornstarch will thicken the filling as it bakes, giving it a smooth consistency.
Lemon Juice: 2 tablespoons of fresh lemon juice enhance the tangy flavor of the blueberries and help balance the sweetness.
Vanilla Extract: 1 teaspoon of vanilla extract adds depth to the fruity filling.
Pinch of Salt: A small pinch of salt to highlight the natural sweetness of the blueberries.

For the Crumble Topping:

All-Purpose Flour: 1 cup of flour forms the base for the crumble topping, which adds a crisp texture on top.
Granulated Sugar: ¼ cup of sugar sweetens the crumble topping.
Unsalted Butter: ¼ cup of cold butter helps create a crumbly, buttery topping.
Old-Fashioned Rolled Oats: 1/2 cup of oats adds texture and chewiness to the topping.
Cinnamon: ½ teaspoon of cinnamon adds warmth and a delicious hint of spice.

Step-by-Step Instructions

1. Preheat the Oven and Prepare the Pan

Start by preheating your oven to 350°F (175°C). Line a 9×9-inch baking dish with parchment paper, leaving some overhang so you can easily lift the bars out of the pan later. Lightly grease the parchment paper to prevent sticking.

2. Make the Crust

In a large mixing bowl, whisk together 1 ½ cups of all-purpose flour, ¼ cup granulated sugar, and a pinch of salt. Add in the softened ½ cup of unsalted butter and 1 egg. Mix using an electric mixer or your hands until the dough comes together into a crumbly mixture. Press the dough evenly into the bottom of the prepared baking dish. You want it to cover the entire bottom of the dish in an even layer.

3. Prepare the Blueberry Filling

In a separate bowl, combine 2 cups of fresh blueberries, ½ cup granulated sugar, 2 tablespoons of cornstarch, 2 tablespoons of fresh lemon juice, 1 teaspoon of vanilla extract, and a pinch of salt. Gently stir the mixture, making sure the blueberries are well coated in the sugar and cornstarch mixture. Pour this filling over the prepared crust, spreading it out evenly.

4. Make the Crumble Topping

For the crumble topping, combine 1 cup of all-purpose flour, ¼ cup granulated sugar, ½ teaspoon of cinnamon, and 1/2 cup rolled oats in a mixing bowl. Cut in the ¼ cup of cold butter using a pastry cutter or your fingers until the mixture forms coarse crumbs. Sprinkle the crumble topping evenly over the blueberry filling.

5. Bake the Blueberry Jamboree Bars

Place the baking dish in the preheated oven and bake for 40-45 minutes. The crust should be golden brown, and the blueberry filling should be bubbling. The crumble topping should also turn a beautiful golden color. If the edges of the crust are browning too quickly, cover the dish loosely with aluminum foil to prevent burning.

6. Cool and Slice

Once the bars are done baking, remove them from the oven and allow them to cool completely in the pan on a wire rack. This will help the filling set and make it easier to slice. Once fully cooled, lift the bars out of the pan using the parchment paper overhang. Slice them into squares or rectangles as desired.

How to Serve Blueberry Jamboree Bars

These blueberry jamboree bars are delicious on their own, but you can elevate the experience by serving them with:

Whipped Cream: A dollop of freshly whipped cream complements the tartness of the blueberries and adds richness.
Vanilla Ice Cream: Serve a warm slice of the bars with a scoop of vanilla ice cream for the ultimate treat.
Lemon Zest: Garnish with freshly grated lemon zest for an extra citrusy pop.
Fresh Mint: A few sprigs of fresh mint can add a burst of color and a refreshing touch to the dessert.

Storing Blueberry Jamboree Bars

At Room Temperature: You can store the bars at room temperature for up to 3 days in an airtight container.
In the Fridge: For longer storage, place the bars in the fridge where they will last up to 5 days.
Freezing: These bars freeze really well! Place the bars in an airtight container or a freezer-safe ziplock bag and store them in the freezer for up to 2 months. Let them thaw at room temperature before serving.
