Instructions:
Prepare the Pan and Preheat the Oven
Begin extract by preheating your oven to 375°F (190°C). This ensures that your bars bake evenly and develop a lovely golden-brown crust. Next, line an 8×8 inch baking pan with parchment paper, leaving an overhang on two opposite sides. This overhang will act as handles, making it incredibly easy to lift the baked bars out of the pan once they’ve cooled. Make sure the parchment paper covers the bottom and sides of the pan completely to prevent any sticking.
Create the Oat Crum extractble Base
In a medium-sized bowl, combine the all-purpose flour, rolled oats, and the first portion of granulated sugar (140 grams or 2/3 cup). Whisk these dry ingredients together until they are well incorporated. This forms the foundation of our delicious bars. Now, pour in the melted and cooled unsalted butter. Use a fork or a spatula to gently mix everything together until the mixture resembles coarse crum extractbs. It’s important that the butter is cooled; if it’s too hot, it can cook the flour and create a gummy texture. You want just enough moisture to bind the crum extractbs together, but not so much that it becomes a dough. Once mixed, press about two-thirds of this crum extractb mixture evenly into the bottom of your prepared baking pan. Take your time with this step, pressing firmly and ensuring a compact and even layer. This base will bake into a sturdy, delightful crust for your blueberry filling.
Whip Up the Vibrant Blueberry Filling
In a separate bowl, gently toss the fresh blueberries with the remaining granulated sugar (50 grams or 1/4 cup), cornstarch, lemon juice, and lemon zest. The cornstarch is crucial here; it acts as a thickener, preventing the blueberry filling from becoming too runny during baking and ensuring that wonderfully jammy texture we all love. The lemon juice and zest add a bright, zesty counterpoint to the sweetness of the berries, cutting through the richness and enhancing their natural flavor. Be careful not to overmix here; you want the blueberries to remain mostly intact, with just a light coating of the sugar and cornstarch mixture. A gentle stir is all that’s needed.
Assemble and Bake the Bars
Evenly spread the prepared blueberry filling over the compacted oat crum extractble base in the baking pan. Make sure to distribute the blueberries as uniformly as possible, covering the entire surface. Once the blueberry layer is in place, sprinkle the remaining one-third of the oat crum extractble mixture evenly over the top of the blueberries. This creates a beautiful streusel-like topping that will become wonderfully crisp and golden as it bakes. Place the pan in your preheated oven and bake for approximately 30-40 minutes. You’re looking for the topping to be golden brown and the blueberry filling to be bubbly around the edges. If you notice the topping browning too quickly, you can loosely tent the pan with aluminum foil for the remainder of the baking time.
Cool and Enjoy Your Delicious Creation
This is perhaps the hardest part – waiting! Once baked, remove the pan from the oven and place it on a wire rack to cool completely. This is a critical step for the bars to set properly. If you try to cut into them while they are still warm, they will likely fall apart. Patience is key here! Once completely cooled, use the parchment paper overhangs to carefully lift the entire block of bars out of the pan. Transfer it to a cutting board and slice into your desired bar size. I find that about 9 or 12 bars work well, but you can adjust them to your preference. These bars are fantastic on their own, but they are also delicious served with a dollop of yogurt, a drizzle of honey, or even a scoop of vanilla ice cream for a truly decadent treat. Store any leftover bars in an airtight container at room temperature for up to 3 days, or in the refrigerator for longer storage. Enjoy every delightful, fruity, and crum extractbly bite!

Conclusion:
These Blueberry Oatmeal Bars are an absolute triumph!

Don’t hesitate to get creative with variations! You can swap the blueberries for other berries like raspberries or blackberries, or even add a sprinkle of cinnamon or nutmeg for an extra flavor boost. Chopped nuts like almonds or walnuts would also be a wonderful addition for added crunch.
