Blueberry Oat Crumble Bars – Home Cooking Adventure

These Blueberry Oat Crumble Bars are a delightful treat perfect for breakfast, a snack, or dessert. These bars feature a luscious blueberry filling sandwiched between layers of crumbly, buttery oat mixture.

The base and topping are made from a blend of rolled oats, flour, sugar, and butter, creating a rich and crispy crust that pairs perfectly with the juicy fruit center. The blueberry filling enhanced with lemon juice is bursting with flavor and balances perfectly the sweetness.

Easy to prepare, these bars come together in a few simple steps. First, press the oat mixture into a baking dish to form the crust, followed by a generous layer of blueberry filling. Crumble the remaining oat mixture on top before baking to golden perfection.

These Blueberry Oat Crumble Bars are not only delicious but also nutritious, providing a good source of fiber and antioxidants from the oats and blueberries. They are perfect for any time of day and are sure to satisfy both kids and adults alike.

How to make Blueberry Oat Crumble Bars

Begin by preheating your oven to 350°F (180°C). Slightly grease a 9×13 inch (23×33 cm) pan and line it with parchment paper, ensuring that the edges extend beyond the sides of the pan to make it easier to lift the bars out.

In a bowl, combine the flour, oats, sugar, baking powder, and salt. Add the butter and vanilla extract, stirring until the mixture combines well and crumbly. Press ⅔ of this crumb mixture firmly into the bottom of the prepared pan to form the crust.

Next, place the blueberries into a separate bowl. Add the sugar, lemon juice, and cornstarch, then toss to coat the blueberries evenly. Spread the blueberry mixture over the crust in the pan.

Sprinkle the reserved ⅓ of the crumb mixture over the top of the blueberries.

Bake in the preheated oven for 40-50 minutes, or until the top is lightly browned.

Allow the bars to cool completely in the pan before cutting them into squares. Store any leftovers in an airtight container at room temperature or refrigerate for up to 4 days.
