Ingredients
For the Oat Crust and Topping
– 1 1/2 cups all-purpose flour
– 1 1/2 cups old-fashioned rolled oats
– 3/4 cup brown sugar
– 1/2 teaspoon baking powder
– 1/4 teaspoon salt
– 1 cup unsalted butter, melted
– 1 teaspoon vanilla extract
For the Blueberry Filling
– 2 cups fresh or frozen blueberries
– 1/3 cup granulated sugar
– 2 tablespoons cornstarch
– 1 tablespoon lemon juice
– 1/2 teaspoon vanilla extract
Instructions
1. Prepare the Pan
Preheat your oven to 350°F (175°C). Line an 8×8-inch baking pan with parchment paper, leaving some overhang for easy removal.
2. Make the Oat Mixture
In a large bowl, combine the flour, rolled oats, brown sugar, baking powder, and salt. Stir in the melted butter and vanilla until the mixture becomes evenly moistened and crumbly.
3. Make the Blueberry Filling
In a separate bowl, gently combine the blueberries, sugar, cornstarch, lemon juice, and vanilla. Stir carefully so the blueberries remain mostly intact.
4. Form the Base
Press about two-thirds of the oat mixture firmly into the bottom of the prepared pan. Make sure it forms an even layer.
5. Add the Blueberries
Spread the blueberry mixture evenly over the oat base.
6. Add the Crumble Topping
Sprinkle the remaining oat mixture over the blueberries, gently pressing some of it together to create a delicious crumbly topping.
7. Bake
Bake for 40–45 minutes, or until the top is golden brown and the blueberry filling is bubbling around the edges.
8. Cool and Slice
Allow the bars to cool completely in the pan before slicing. For cleaner cuts, refrigerate them for about 30 minutes after cooling.
Tips for the Best Blueberry Oat Bars
– Old-fashioned oats provide the best chewy texture.
– If using frozen blueberries, there’s no need to thaw them first.
– Don’t skip the cornstarch, as it helps thicken the blueberry filling.
– Let the bars cool completely before cutting so they hold together.
– Add a little lemon zest to the filling for extra brightness.
– For a richer flavor, lightly toast the oats before mixing them into the crumble.
Serving Suggestions
Serve these bars with coffee or tea for breakfast or an afternoon snack. For dessert, warm a square slightly and serve it with vanilla ice cream or a spoonful of whipped cream.
Storage
Store cooled bars in an airtight container at room temperature for up to 2 days or refrigerate for up to 5 days. They can also be frozen individually and thawed when needed.

These Blueberry Oat Bars combine a buttery oat crumble with a sweet, tangy blueberry center for an irresistible homemade treat. They’re easy to make, simple to store, and delicious enough to serve for breakfast, snacks, or dessert.
