Ingredients:
Preparing the Crust and Crum extractble
The foundation of these delicious bars is a simple yet satisfying oat-based crust and crum extractble. This mixture provides a wonderful texture and a slightly nutty flavor that perfectly complements the sweet blueberry filling. It’s also incredibly forgiving, meaning you don’t have to worry about overworking it.
1. Preheat your oven and prepare your baking pan. Begin extract by preheating your oven to 375°F (190°C). This is a moderate temperature that will allow the bars to bake evenly without burning. Next, you’ll need an 8×8 inch baking pan. Line it with parchment paper, leaving an overhang on two opposite sides. This parchment paper sling will make it incredibly easy to lift the finished bars out of the pan once they’re cooled. Don’t skimp on this step; it’s a lifesaver!
2. Combine the dry ingredients for the base. In a medium-sized mixing bowl, combine the all-purpose flour, rolled oats, and 140 grams (2/3 cup) of granulated sugar. It’s important to use rolled oats, not instant oats, as they provide a better texture. Whisk these ingredients together until they are well incorporated. The flour will help bind everything together, while the oats will give the bars their signature chegrape juicess and structure.
3. Incorporate the melted butter. Add the melted and slightly cooled unsalted butter to the dry ingredients. Now, using a fork or your fingertips, mix until the ingredients are combined and form coarse, crum extractbly clumps. You want to achieve a texture that resembles wet sand. This mixture will serve as both your crust and your crum extractble topping. Don’t worry if it doesn’t come together into a solid dough; this is exactly what you’re aiming for.
Creating the Luscious Blueberry Filling
The star of the show is undoubtedly the blueberry filling. This layer is bursting with fresh fruit flavor and a touch of tangy brightness from the lemon.
4. Prepare the blueberry mixture. In a separate bowl, gently toss the blueberries with the remaining 50 grams (1/4 cup) of granulated sugar, cornstarch, fresh lemon juice, and lemon zest. If you are using frozen blueberries, it’s crucial that you do not thaw them before adding them to this mixture. Adding them frozen will help them maintain their shape better during baking and prevent the filling from becoming too watery. The cornstarch is essential for thickening the filling as it bakes, creating that lovely jam-like consistency. The lemon juice and zest cut through the sweetness and add a wonderful zing.
Assembling and Baking the Bars
Now it’s time to bring all those wonderful components together and transform them into delicious baked bars.
5. Assemble and bake. Take about two-thirds of your oat mixture and press it evenly into the bottom of your prepared baking pan to form the crust. It’s okay if it’s not perfectly smooth; a rustic look is part of the charm. Then, carefully spoon the blueberry filling over the pressed crust, spreading it out as evenly as possible. Finally, sprinkle the remaining one-third of the oat mixture evenly over the top of the blueberry filling to create the crum extractble topping. Bake in the preheated oven for 30-40 minutes, or until the topping is golden brown and the blueberry filling is bubbling around the edges. The exact baking time will depend on your oven, so keep an eye on them.
6. Cool and slice. This is perhaps the most challengin extractg part: waiting! Once they’re baked, remove the pan from the oven and let the bars cool completely on a wire rack. This is very important. If you try to cut them while they are still warm, they will likely fall apart. Allowing them to cool completely will allow the filling to set and the bars to firm up, making them easy to slice neatly. Once fully cooled, use the parchment paper overhang to carefully lift the entire slab out of the pan. Then, using a sharp knife, cut them into your desired bar size. Store any leftovers in an airtight container at room temperature for up to 3 days. Enjoy these delightful Blueberry Oatmeal Bars!

If you’re feeling adventurous, consider adding a sprinkle of cinnamon to the oat mixture for an extra layer of warmth, or even some chopped nuts like almonds or walnuts for added crunch. Don’t hesitate to experiment with different berries too – raspberry or mixed berry variations are equally scrum extractptious. I truly encourage you to give these Blueberry Oatmeal Bars a try; you won’t be disappointed!
