Ingredients
Scale
Blueberry Topping:
- 2 cups fresh or frozen blueberries
- ⅓ cup granulated sugar
- 1 tablespoon cornstarch
- 1 teaspoon lemon juice
- 1 teaspoon vanilla extract
Base and Crumble Ingredients:
- 1 ½ cups old-fashioned oats
- 1 ¼ cups all-purpose flour
- ¾ cup unsalted butter, melted (170 grams)
- ½ cup brown sugar, packed
- ½ teaspoon baking powder
- ½ teaspoon cinnamon (optional)
- ¼ teaspoon salt
Instructions
- Prepare the oven environment by heating to 350F (175C) and creating a non-stick foundation using parchment paper in an 8-inch square baking vessel.
- Craft the base and topping mixture by combining rolled oats, flour, brown sugar, baking powder, ground cinnamon, and a pinch of salt in a spacious mixing bowl. Introduce melted butter and blend until the ingredients form a delicate, crumbly consistency.
- Establish the foundational crust by firmly pressing two-thirds of the oat mixture into the prepared pan, creating an even, compact layer.
- Generate the fruit compote by simmering fresh blueberries with granulated sugar, cornstarch, fresh lemon juice, and vanilla extract in a saucepan over medium heat. Stir continuously for 5-7 minutes until the mixture transforms into a thick, glossy filling.
- Allow the blueberry mixture to cool momentarily, then carefully distribute it across the prepared oat crust, ensuring an uniform coverage.
- Scatter the remaining oat crumble mixture gracefully over the blueberry layer, creating a textured surface.
- Transfer the pan to the preheated oven and bake for 30-35 minutes, monitoring until the top achieves a golden-brown hue and the filling bubbles enticingly.
- Remove from the oven and permit the bars to cool completely before slicing into precise squares for serving.
Notes
- Choose fresh, ripe blueberries for the most vibrant and intense flavor in your filling.
- Use rolled oats instead of quick oats to maintain a better texture and prevent the bars from becoming too dense.
- Ensure the blueberry filling is slightly cooled before spreading to prevent the crust from becoming soggy and maintain crisp layers.
- For a gluten-free version, swap regular flour with almond flour or a certified gluten-free flour blend to accommodate dietary restrictions.
