Gather the ingredients
Before you get started, make sure you have all your ingredients ready to go. Here’s what you’ll need:
- 1 cup old-fashioned rolled oats (gluten-free if needed)
- ¾ cup white whole wheat flour (or an all-purpose alternative)
- ⅓ cup light brown sugar
- ½ teaspoon ground cinnamon
- ¼ teaspoon kosher salt
- 6 tablespoons unsalted butter, melted (or coconut oil for a vegan option)
- 2 cups fresh blueberries (about 10 ounces)
- 1 teaspoon cornstarch
- 1 tablespoon freshly squeezed lemon juice
- 1 tablespoon granulated sugar (divided)
For the optional glaze:
- ½ cup powdered sugar (sifted)
- ½ teaspoon pure vanilla extract
- 1 tablespoon milk (any kind)
Having everything prepared upfront makes the cooking process smoother and more enjoyable.
Prepare the crust
Once you have your ingredients ready, it’s time to whip up the crust. Start by preheating your oven to 375°F and lining an 8x8-inch baking pan with parchment paper.
In a medium bowl, combine the rolled oats, white whole wheat flour, brown sugar, ground cinnamon, and kosher salt. Pour in the melted butter (or coconut oil) and mix until the dry ingredients are evenly moistened. Reserve about ½ cup of this crumble mixture for topping later, then press the remainder firmly into the bottom of your prepared pan.
It’s important to really press down to ensure the crust holds together, so don’t be shy!
Layer the blueberries
Next, sprinkle half of the blueberries over the crust. To enhance the berry flavor, toss the berries lightly with cornstarch, lemon juice, and half of the granulated sugar. This will help thicken the juices as they bake. Scatter the remaining blueberries over the top, followed by the rest of the sugar and the reserved crumble mixture.
Bake the bars
Now comes the exciting part! Bake your blueberry oatmeal bars in the preheated oven for 30 to 40 minutes, until the fruit is bubbly and the crumb topping turns a lovely golden color. Once baked, let them cool completely on a wire rack—but if you're in a hurry, the refrigerator works too!
Add the glaze
While the bars are cooling, you can prepare a simple glaze if you’d like to add a touch of sweetness. Whisk together the powdered sugar, vanilla extract, and milk until smooth.
Once your bars have cooled, lift them out of the pan using the parchment paper and drizzle the glaze over the top. Slice into squares, and you're ready to serve!
These easy blueberry oatmeal bars are perfect for meal prep or a grab-and-go breakfast. Enjoy!

Variations on Blueberry Oatmeal Bars
Vegan blueberry oatmeal bars
Looking for a plant-based option? Simply substitute the melted unsalted butter with melted coconut oil, and you'll have delicious vegan blueberry oatmeal bars that everyone can enjoy. To keep it dairy-free, ensure any milk in the glaze is non-dairy as well. These bars boast the same delightful taste and texture, making them perfect for breakfast or an afternoon snack with your favorite plant-based milk.
Gluten-free blueberry oatmeal bars
If you're following a gluten-free diet, don’t fret! You can easily whip up gluten-free blueberry oatmeal bars by swapping out the white whole wheat flour for a high-quality 1:1 gluten-free baking mix. This small adjustment allows everyone to savor the mouth-watering goodness of these bars while keeping them gluten-free. Try serving them at gatherings; you may just convert a few skeptics!
