Step-by-step preparation of Blueberry Oatmeal Bars
Making delicious blueberry oatmeal bars is a straightforward process that results in a scrumptious treat perfect for breakfast, a snack, or dessert. Let’s walk through the preparation steps together!
Preheat the oven and prepare the baking pan
Begin by placing a rack in the center of your oven and preheating it to 375°F (190°C). While the oven warms up, take an 8×8-inch baking pan and line it with parchment paper, ensuring that the edges overlap two sides. This will create handy "handles" for easy removal once the bars cool (and it simplifies cleanup!).
Prepare the oat and flour mixture
In a medium bowl, combine 1 cup old-fashioned rolled oats with ¾ cup white whole wheat flour (or your preferred substitute). Add in ⅓ cup light brown sugar, ½ teaspoon ground cinnamon, and a pinch of kosher salt. This delightful blend serves as the base of our bars. Now pour in 6 tablespoons of melted butter (or melted coconut oil for a vegan option) and stir until you achieve a crumbly texture. Make sure to save ½ cup of this mixture aside; we’ll sprinkle it on top later.
Create the berry filling
Now, let's focus on that juicy filling. In the same bowl, add 2 cups of fresh blueberries (about 10 ounces). For those who might wish to experiment with frozen blueberries, just ensure they’re thawed completely. Sprinkle 1 teaspoon cornstarch and squeeze in 1 tablespoon of freshly squeezed lemon juice over the berries. To sweeten things up, add ½ tablespoon granulated sugar and gently toss everything together.
Assemble the bars for baking
Using the remaining crumble mixture, press most of it firmly into the bottom of your prepared baking pan. It’s vital to really press down to create a solid base. Next, scatter half of the blueberry mixture over the crust, followed by the remaining bluebs and a dash of ½ tablespoon granulated sugar. Finally, top it off with the reserved crumbs and get ready to bake!
Bake to perfection and cool
Transfer your assembled blueberry oatmeal bars into the oven and bake for 30 to 40 minutes. You’ll know they’re done when the fruit bubbles, and the crumb topping appears beautifully golden. Once baked, let them cool completely in the pan on a wire rack (or speed up this process by popping them in the refrigerator).
Drizzle with glaze (optional)
If you're looking to add a touch of sweetness, whip up a quick glaze! In a bowl, combine ½ cup sifted powdered sugar, ½ teaspoon pure vanilla extract, and 1 tablespoon of milk. Drizzle this creamy goodness over your cooled bars to elevate them to the next level. Slice them up, and voila—your perfect blueberry oatmeal bars are ready to enjoy!

Cooking Tips and Notes for Blueberry Oatmeal Bars
Tips for Achieving the Perfect Texture
To ensure your blueberry oatmeal bars have that delightful chewy yet crumbly texture, be sure to press the crust firmly into your baking pan. A good grip helps maintain structure during baking. If you like a slightly softer bite, reduce the baking time by a few minutes. If using fresh blueberries, opt for plump, firm ones to prevent excess moisture in your bars.
Storage Tips for Homemade Oatmeal Bars
To keep your blueberry oatmeal bars fresh, store them in an airtight container in the refrigerator for up to five days. For longer storage, freeze the unglazed bars. Wrap them tightly in plastic, and they can last for about three months. When ready to enjoy, thaw in the fridge overnight before adding the glaze for that perfect finish.
