Ingredients:
- 14 ounces 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 plus 6 tablespoons)
- 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 topping)
Preparing the Blueberry Filling
Step 1: Cook the Blueberries
First, let’s get our delicious blueberry filling ready. In a medium saucepan, combine the 14 ounces of frozen wild blueberries, 1/4 cup of granulated sugar, and 2 tablespoons of fresh lemon juice. The lemon juice is key here; it brightens the flavor of the blueberries and balances the sweetness beautifully. Stir everything together and place the saucepan over medium heat. We want the blueberries to start releasing their juices and softening. As they heat up, gently mash some of them with the back of your spoon or a potato masher. This will help create a thicker, more jam-like consistency. Don’t feel the need to mash them all; leaving some whole will give a lovely texture to the finished bars.
Step 2: Thicken the Filling
Once the blueberry mixture is simmering and has been cooking for about 5-7 minutes, it’s time to thicken it up. In a small bowl, whisk together the 1/2 cup of water and 1 tablespoon of cornstarch until the cornstarch is completely dissolved and there are no lumps. This is our cornstarch slurry. Slowly pour this slurry into the simmering blueberry mixture while continuously stirring. Continue to cook and stir for another 2-3 minutes, or until the filling has visibly thickened to a glossy, jam-like consistency. It should coat the back of a spoon. Remove the saucepan from the heat and set the blueberry filling aside to cool completely. It will thicken even more as it cools down, so don’t worry if it seems a little loose at first.
Making the Cookie Bar Base and Topping
Step 3: Cream the Butter and Sugar
Now, let’s prepare the cookie base that will hold our blueberry filling. In a large mixing bowl, add the 14 tablespoons of softened unsalted butter. Make sure your butter is truly softened – it should give slightly when pressed with your finger but not be melted. To this, add 1/2 cup of granulated sugar. Using an electric mixer (or a sturdy whisk and some elbow grease!), cream the butter and sugar together until the mixture is light and fluffy. This process incorporates air, which is crucial for a tender cookie texture. This usually takes about 3-5 minutes on medium speed.
Step 4: Incorporate Wet Ingredients and Flour
Next, add the 1/2 teaspoon of vanilla extract to the creamed butter and sugar mixture. Vanilla extract enhances all the other flavors in the recipe. Then, crack in the 1 large egg. Beat again until everything is well combined and smooth. Now it’s time to add the dry ingredients. Gradually add the 2 1/4 cups of all-purpose flour to the wet ingredients. Mix on low speed or by hand until just combined. Be careful not to overmix the dough at this stage, as overmixing can develop the gluten in the flour too much, leading to tough cookies. The dough will be thick and somewhat stiff.
Step 5: Assemble and Bake the Bars
Preheat your oven to 375°F (190°C). Line a 9×13 inch baking pan with parchment paper, leaving an overhang on the sides. This will make it super easy to lift the baked bars out of the pan. Press about two-thirds of the cookie dough evenly into the bottom of the prepared baking pan to form the base. Make sure it’s a consistent layer. Spread the cooled blueberry filling evenly over the cookie base, reaching close to the edges. Now, crum extractble the remaining one-third of the cookie dough over the blueberry filling. You can use your fingers to createrum extractall crumbles. Finally, sprinkle the 1/4 cup of flaked almonds and the optional 2 tablespoons of pearl sugar over the top. The almonds will toast beautifully and add a lovely crunch, while the pearl sugar provides a delightful sparkle and extra sweetness. Bake for 30-35 minutes, or until the edges are golden brown and the topping is set. Let the bars cool completely in the pan before cutting into squares.
