Preparing Blueberry Oatmeal Bars
Creating blueberry oatmeal bars at home is not only simple but also a wholesome way to enjoy a snack that is packed with flavor. Follow these easy steps to make your delicious bars from scratch!
Gather Your Ingredients
Before diving in, it's essential to get organized. Here’s what you'll need:
- 1 cup old-fashioned rolled oats (gluten-free if needed)
- ¾ cup white whole wheat flour (or 1:1 baking flour for a gluten-free option)
- ⅓ cup light brown sugar
- ½ teaspoon ground cinnamon
- ¼ teaspoon kosher salt
- 6 tablespoons unsalted butter, melted (or melted coconut oil for vegan)
- 2 cups fresh blueberries (approximately 10 ounces)
- 1 teaspoon cornstarch
- 1 tablespoon freshly squeezed lemon juice
- 1 tablespoon granulated sugar (divided)
If you want to add a sweet finishing touch, consider the optional vanilla glaze made with powdered sugar, vanilla extract, and milk.
Prepare the Crust Mixture
Begin by preheating your oven to 375 degrees F. As the oven warms, line an 8x8-inch baking pan with parchment paper, leaving some overhang to help lift the bars out later.
In a medium bowl, mix together the rolled oats, white whole wheat flour, brown sugar, ground cinnamon, and kosher salt. Pour in the melted butter and stir until your mixture forms clumps, ensuring that the dry ingredients are well moistened. Remember to set aside about ½ cup of this crumble mixture—it’s essential for the topping!
Scatter Blueberries and Assemble the Bars
Next, press the remaining crumble mixture firmly into the bottom of your prepared baking pan using either your fingers or the back of a measuring cup—this will help it hold together. Go ahead and sprinkle half of the blueberries over the crust, then uniformly dust them with cornstarch, lemon juice, and ½ tablespoon of granulated sugar. Top with the remaining blueberries and finish off with another sprinkle of sugar and the reserved crumb mixture. Voila!
Bake the Bars to Perfection
Now it's time to pop your assembled masterpiece into the oven. Bake for 30 to 40 minutes until the fruit is bubbly and the topping turns a beautiful golden brown. Once done, let it cool completely on a wire rack (or chill in the fridge to speed up this process).
Create the Optional Vanilla Glaze
While waiting for your bars to cool, why not prepare the optional glaze? In a medium bowl, combine ½ cup of sifted powdered sugar, ½ teaspoon of pure vanilla extract, and 1 tablespoon of milk. Stir until smooth, adjusting the milk to achieve your desired consistency.
Once your blueberry oatmeal bars cool, lift them out using the parchment paper handles, drizzle with the glaze, slice, and enjoy a delightful treat that’s perfect for breakfast or a post-work snack!

Variations on Blueberry Oatmeal Bars
Gluten-Free Blueberry Oatmeal Bars
Making blueberry oatmeal bars gluten-free is a breeze! Simply swap the white whole wheat flour for a high-quality 1:1 gluten-free baking mix, ensuring everyone can enjoy a delicious treat. Be sure to double-check that your oats are certified gluten-free to dodge any cross-contamination. The flavor and textures remain delightful—just as satisfying as the traditional version.

And if you're looking for a fruit twist, feel free to swap out blueberries for fresh raspberries or cherries.
