Blueberry Oatmeal Bars
These Blueberry Oatmeal Bars are a delightful treat that’s perfect for breakfast, a snack, or even a light dessert. They combine the wholesome goodness of oats with the sweet, tart burst of fresh blueberries, all held together by a buttery, crum extractbly base. I love making these for weekend brunches or packing them up for a portable snack on busy days. They’re incredibly forgiving to make, making them a great recipe for bakers of all skill levels. The combination of textures – the slightly chewy oats, the tender blueberries, and the crum extractbly topping – is simply irresistible.
Ingredients:
*The butter should be melted and then allowed to cool slightly before incorporating it into the dry ingredients. This prevents it from cooking the flour too quickly and ensures a better texture for the crust. It should still be pourable but not hot.
**You can use fresh or frozen blueberries for this recipe. If using frozen blueberries, do not thaw them before adding them to the filling. This will help prevent them from becoming too mushy during baking.
Instructions:
Prepare the Crum extractble Base and Topping
Preheat your oven to 350°F (175°C). Grease and line an 8×8 inch (20×20 cm) baking pan with parchment paper, leaving an overhang on two sides. This overhang will make it easier to lift the bars out of the pan once they are baked and cooled. In a medium bowl, combine the all-purpose flour, rolled oats, and 140 grams (2/3 cup) of granulated sugar. Whisk these dry ingredients together thoroughly to ensure they are evenly distributed. Now, pour in the melted and cooled unsalted butter. Use a fork or your fingertips to mix everything together until the mixture resembles coarse crum extractbs. This mixture will serve as both the base and the crum extractble topping for your bars.
Form the Base Layer
Take about two-thirds of the crum extractb mixture and press it firmly and evenly into the bottom of the prepared baking pan. You want to create a compact layer that will hold its shape when baked. Using the bottom of a glass or your hands, make sure the base is as flat and even as possible. This will ensure consistent baking and a good structure for your bars.
Prepare the Blueberry Filling
In a separate bowl, gently toss the blueberries with the remaining 50 grams (1/4 cup) of granulated sugar, cornstarch, tablespoon of lemon juice, and the lemon zest. The cornstarch is crucial here as it will help thicken the blueberry juices as they cook, creating a lovely, jammy filling rather than a watery one. The lemon juice and zest add a wonderful brightness that perfectly complements the sweetness of the blueberries and prevents them from tasting too one-dimensional. Be gentle when mixing to avoid crushing the berries too much.
Assemble and Bake
Spoon the prepared blueberry filling evenly over the pressed-down oat base in the baking pan. Try to distribute the blueberries so they are in a single layer as much as possible, though some mounding is fine. Now, take the remaining one-third of the crum extractb mixture and sprinkle it evenly over the top of the blueberry filling. This will form the delicious, slightly crunchy crum extractble topping. Bake in the preheated oven for 35-45 minutes, or until the crum extractble topping is golden brown and the blueberry filling is bubbling around the edges. The baking time can vary depending on your oven, so keep an eye on it. You’re looking for that lovely toasted oat and golden-brown hue.
Cool and Cut
Once baked, remove the pan from the oven and place it on a wire rack to cool completely. This is a very important step for getting clean cuts. Resist the urge to cut into them while they are still warm, as the filling will be runny and the bars will likely fall apart. Allow them to cool for at least 2-3 hours. For even cleaner cuts, you can place the cooled bars in the refrigerator for about 30 minutes before cutting. Once completely cooled, use the parchment paper overhang to lift the entire block out of the pan. Place it on a cutting board and use a sharp knife to cut into bars or squares of your desired size. These bars can be stored in an airtight container at room temperature for up to 3 days, or in the refrigerator for up to a week. Enjoy these delightful Blueberry Oatmeal Bars!
