Instructions:
Preparing the Oat Base
The foundation of our delicious bars is a simple yet satisfying oat and flour mixture. First, preheat your oven to 350°F (175°C). This is a crucial step to ensure even baking. Prepare an 8×8 inch baking pan by lining it with parchment paper, leaving some overhang on the sides. This will make lifting the baked bars out of the pan a breeze. In a medium bowl, combine the all-purpose flour, rolled oats, and 140 grams (2/3 cup) of granulated sugar. Give these dry ingredients a good whisk to ensure they are well combined and there are no pockets of flour. Now, pour in the melted and slightly cooled unsalted butter. The butter should not be hot, as it could start to cook the flour, so just let it sit for a few minutes after melting. Using a fork or your fingertips, mix the butter into the dry ingredients until the mixture resembles coarse crum extractbs. You want it to be moist enough to hold together when squeezed, but not greasy. This crum extractbly mixture will form the bottom and top layers of your bars.
Creating the Vibrant Blueberry Filling
Next, we’ll prepare the star of the show – the luscious blueberry filling. In a separate medium bowl, gently combine the fresh or frozen blueberries. If you’re using frozen blueberries, there’s no need to thaw them completely, as they will cook down in the oven. Add the remaining 50 grams (1/4 cup) of granulated sugar to the blueberries. This sugar will help to draw out some of the natural juices and sweeten the filling. Sprinkle in the cornstarch. Cornstarch is essential here; it acts as a thickener, preventing your filling from becoming too runny once baked. Then, add the fresh lemon juice and the finely grated lemon zest. The lemon juice and zest are absolute game-changers for blueberry fillings. They brighten the flavor, cut through the sweetness, and add a delightful tang that perfectly complements the berries. Gently toss everything together until the blueberries are evenly coated with the sugar, cornstarch, and lemon mixture. Be careful not to overmix, as you want the blueberries to remain mostly intact.
Assembling and Baking the Bars
Now it’s time to bring it all together. Take about two-thirds of the oat mixture and press it firmly into the bottom of your prepared baking pan. You want a compact and even layer, as this will form the base of your bars. You can use the bottom of a glass or a measuring cup to help you press it down evenly. Once the base is in place, spoon the prepared blueberry filling evenly over the oat base. Try to spread the blueberries out so you get a good distribution in every bite. Finally, crum extractble the remaining one-third of the oat mixture over the top of the blueberry layer. Don’t worry about creating a perfectly smooth top; a rustic crum extractble is exactly what we’re aiming for. Place the pan in the preheated oven and bake for 30-35 minutes, or until the top is golden brown and the blueberry filling is bubbling around the edges. Keep an eye on them during the last few minutes of baking to prevent the edges from burning.
Cooling and Serving
The hardest part is waiting! Once your Blueberry Oatmeal Bars are out of the oven, resist the urge to cut into them immediately. It’s very important to let them cool completely in the pan on a wire rack. This cooling process allows the filling to set properly, ensuring that your bars slice cleanly. If you try to cut them while they are still warm, the filling will likely ooze out. Once completely cooled, use the parchment paper overhang to carefully lift the entire slab out of the pan. You can then place it on a cutting board and slice it into your desired bar size. I usually cut mine into 9 or 12 bars, depending on how indulgent I’m feeling. These bars are delicious on their own, but they also pair wonderfully with a cup of tea or coffee. For an extra treat, you could serve them with a dollop of Greek yogurt or a scoop of vanilla ice cream. Store any leftovers in an airtight container at room temperature for up to 3 days, or in the refrigerator for up to a week.

Frequently Asked Questions:
Can I make these bars ahead of time?
Absolutely! These Blueberry Oatmeal Bars store wonderfully. Once completely cooled, you can keep them in an airtight container at room temperature for up to 3 days, or in the refrigerator for up to a week. They are perfect for meal prepping!
What’s the best way to store leftover bars?
For optimal freshness, store cooled bars in an airtight container. If you plan to keep them for more than a few days, the refrigerator is your best bet. They also freeze beautifully; simply wrap individual bars or the whole batch and freeze for up to 2-3 months. Thaw at room temperature before enjoying.
Can I use frozen blueberries instead of fresh?
Yes, using frozen blueberries is perfectly fine! Just be aware that they may release more moisture as they bake. You can toss them with a tablespoon of flour before adding them to the batter to help absorb some of that extra liquid. You might also find that the bars take a little longer to bake.
