Ingredients:
- 14 oz frozen wild blueberries
- 1/4 cup granulated sugar
- 2 tablespoons fresh lemon juice
- 1/2 cup water
- 1 tablespoon cornstarch
- 14 tablespoons unsalted butter, softened (this is 1 stick and 6 tablespoons, or 1 and 3/4 sticks)
- 1/2 cup granulated sugar
- 1/2 teaspoon vanilla extract
- 1 large egg
- 2 1/4 cups all-purpose flour
- 1/4 cup flaked almonds
- 2 tablespoons pearl sugar (optional)
For the Blueberry Filling:
Step 1: Prepare the Blueberry Filling
The first step to creating these delightful Blueberry Pie Cookie Bars is to get our vibrant blueberry filling ready. In a medium saucepan, combine the 14 oz of frozen wild blueberries, 1/4 cup of granulated sugar, and 2 tablespoons of fresh lemon juice. The lemon juice is crucial here, as it not only brightens the flavor of the blueberries but also helps to balance their natural sweetness and adds a lovely tang. Stir these ingredients together and place the saucepan over medium heat.
As the blueberries begin extract to thaw and warm up, they will release their juices. Keep stirring occasionally. Once the mixture comes to a gentle simmer, it’s time to thicken it. In a small bowl, whisk together the 1/2 cup of water with the 1 tablespoon of cornstarch until it forms a smooth slurry with no lumps. This cornstarch slurry is our thickening agent. Gradually pour this slurry into the simmering blueberry mixture while continuously stirring. Continue to cook and stir for about 2-3 minutes, or until the filling has thickened to a jam-like consistency. It should coat the back of a spoon nicely. Once thickened, remove the saucepan from the heat and set it aside to cool completely. It’s important that the filling is cool before assembling the bars to prevent the cookie base from becoming greasy or overly soft. You can speed up this cooling process by transferring the filling to a clean bowl and placing it in the refrigerator.
For the Cookie Base and Topping:
Step 2: Cream the Butter and Sugar
While the blueberry filling is cooling, let’s get started on the cookie part of our Blueberry Pie Cookie Bars. In a large mixing bowl, cream together the 14 tablespoons of softened unsalted butter and the 1/2 cup of granulated sugar. “Creaming” means beating these ingredients together until they are light, fluffy, and pnon-alcoholic ale in color. This process incorporates air into the mixture, which is essential for a tender and delicate cookie texture. You can use an electric mixer (stand mixer with a paddle attachment or a hand mixer) for this, or you can do it vigorously by hand with a whisk or spatula. This usually takes about 3-5 minutes with an electric mixer.
Step 3: Add Wet Ingredients and Combine
Once the butter and sugar are beautifully creamed, it’s time to add the remaining wet ingredients. Add the 1/2 teaspoon of vanilla extract to the bowl. Vanilla extract enhances the overall flavor profile and complements the tartness of the blueberries perfectly. Then, crack in the 1 large egg. Beat these in until they are just combined and the mixture is smooth. Be careful not to overmix at this stage; we just want everything to come together.
Step 4: Incorporate Dry Ingredients and Form Dough
Now, it’s time to add the dry ingredients. In a separate medium bowl, whisk together the 2 1/4 cups of all-purpose flour. Gradually add the flour to the wet ingredients in the large mixing bowl. Mix on low speed with your electric mixer or stir gently with a spatula until the flour is just incorporated and no dry streaks remain. The dough will be thick and slightly sticky, which is exactly what we want for a chewy cookie bar. Do not overwork the dough, as this can lead to tough bars.
Step 5: Assemble and Bake the Bars
Preheat your oven to 375°F (190°C). Grease and flour a 9×13 inch baking pan, or line it with parchment paper, leaving an overhang on the sides to make it easier to lift the bars out later. This is a great tip for easier cleanup and removal. Divide the cookie dough into two portions, roughly one-third and two-thirds. Press the larger portion of dough evenly into the bottom of the prepared baking pan to form the base layer. This might be a bit sticky, so you can lightly flour your hands or use the bottom of a glass to press it down smoothly.
Once the base is formed, carefully spread the cooled blueberry filling evenly over the cookie dough base. Make sure to go all the way to the edges. Now, take the remaining one-third of the cookie dough and crum extractble it over the blueberry filling. You can do this by dropping small pieces of dough randomly across the top, or by gently pressing and flattening small pieces to create a more even topping. Scatter the 1/4 cup of flaked almonds over the top rum extractthe crumbled dough. If you are using the optional pearl sugar, sprinkle it over the almonds and dough for a delightful crunch and sparkle.
Bake for 30-35 minutes, or until the cookie topping is golden brown and the edges of the bars are set. The blueberry filling should be bubbling slightly around the edges. Once baked, remove the pan from the oven and let the bars cool completely in the pan on a wire rack. This cooling time is crucial for the bars to set properly. Once fully cooled, you can use the parchment paper overhang to lift the entire slab out of the pan and cut it into squares or bars. Enjoy your delicious homemade Blueberry Pie Cookie Bars!
