Ingredients:
Preparing the Base
The foundation of these bars is a simple yet delicious oat and flour mixture. It provides that wonderful chewy texture and a slightly nutty flavor that pairs perfectly with the blueberries. The melted butter binds everything together, creating a crum extractbly yet cohesive base that bakes up beautifully.
1. Begin extract by preheating your oven to 350°F (175°C). Line an 8×8 inch baking pan with parchment paper, leaving an overhang on two opposite sides. This parchment paper “sling” will make it incredibly easy to lift the baked bars out of the pan once they’re done. In a medium bowl, whisk together the 140 grams (1 cup) of all-purpose flour (measured by dipping your cup into the flour and sweeping off any excess) and the 144 grams (1 and 1/2 cup) of rolled oats. Add the 140 grams (2/3 cup) of granulated sugar to this dry mixture. Stir everything together until it’s well combined.
2. Pour the 150 grams (2/3 cup) of melted and cooled unsalted butter into the dry ingredients. Use a fork or a spatula to mix until the ingredients are moistened and a crum extractbly dough starts to form. This mixture will not come together into a solid ball of dough; it should remain crum extractbly. This is exactly what you want!
3. Take about two-thirds of this crum extractbly mixture and press it firmly into the bottom of your prepared baking pan. I like to use the bottom of a measuring cup or a flat-bottomed glass to get a nice, even layer. This forms the base of your bars. Make sure it’s packed down well so it holds its shape during baking.
Creating the Blueberry Filling
The star of the show! A bright, slightly tangy blueberry filling cuts through the richness of the oat base and adds a burst of fruity goodness. A touch of cornstarch helps to thicken the juices released by the blueberries, preventing a soggy bar.
4. In a separate bowl, gently toss the 300 grams (2 cups) of blueberries with the 50 grams (1/4 cup) of granulated sugar, 2 teaspoons of cornstarch, 1 tablespoon of lemon juice, and the 1 and 1/2 teaspoons of lemon zest. The lemon zest adds a wonderful fragrant note that complements the blueberries beautifully. Stir carefully so you don’t crush all the berries. The cornstarch will help to thicken the juices as the bars bake, creating a lovely, jammy consistency.
Assembling and Baking
Now it’s time to bring it all together and let the magic happen in the oven.
5. Evenly spread the prepared blueberry mixture over the pressed oat base in the baking pan. Make sure the blueberries are distributed as uniformly as possible. Once the blueberry layer is in place, take the remaining one-third of the crum extractbly oat mixture and sprinkle it evenly over the top of the blueberries. This topping will bake into a delightful, golden-brown crunch.
6. Place the pan in the preheated oven and bake for 35 to 45 minutes, or until the topping is golden brown and the blueberry filling is bubbly around the edges. Keep an eye on it towards the end of the baking time to ensure the topping doesn’t get too dark. The aroma filling your kitchen will be absolutely divine!
Cooling and Cutting
Patience is key here! Letting the bars cool properly ensures clean cuts and the best texture.
7. Once baked, remove the pan from the oven and let the bars cool completely in the pan on a wire rack. This is a crucial step. If you try to cut them while they are still warm, they will likely fall apart. Allowing them to cool allows the filling to set and the oat base to firm up. Once completely cooled, use the parchment paper overhang to lift the entire slab out of the pan. Then, using a sharp knife, cut into squares or bars of your desired size. These bars are best stored in an airtight container at room temperature for up to 3 days, or in the refrigerator for a slightly longer shelf life. Enjoy your homemade Blueberry Oatmeal Bars!
