Ingredients
Scale
Base & Crumble Ingredients:
- 1 cup (120 grams) plain flour
- 3/4 cup (60 grams) old-fashioned oats
- 1/2 cup (100 grams) white sugar
- 1/2 cup (113 grams) unsalted butter, melted
- 1/4 cup (50 grams) dark brown sugar
- 1 large egg yolk
- 1 tablespoon (15 grams) dark brown sugar
- 1/2 teaspoon ground cinnamon
- 1/4 teaspoon sea salt
Blueberry Layer Ingredients:
- 2 cups (280 grams) blueberries, fresh or frozen
- 1/4 cup (50 grams) white sugar
- 2 tablespoons (30 milliliters) fresh lemon juice
- 2 teaspoons (6 grams) cornstarch
Instructions
- Preheat the oven to 350°F and prepare an 8×8 inch baking pan by lining it with foil and lightly greasing with butter.
- Create the foundational crumb mixture by combining dry ingredients, then incorporate melted butter and egg yolk until the texture becomes slightly crumbly and cohesive.
- Separate and set aside 1 cup of the crumb mixture for the topping, then firmly press the remaining mixture into the prepared pan to form a solid base layer.
- Craft the blueberry filling by gently folding blueberries with lemon juice, sugar, and cornstarch, ensuring the berries are evenly coated and glossy.
- Spread the blueberry mixture uniformly across the pressed base, creating an even fruity layer that reaches the edges of the pan.
- Enhance the reserved crumb mixture by mixing in additional brown sugar, then delicately sprinkle and crumble the topping over the blueberry layer.
- Transfer the pan to the preheated oven and bake for 40-45 minutes, watching for a golden-brown topping and bubbling fruit filling.
- Remove from oven and allow the bars to cool completely at room temperature for approximately 3 hours, which helps the filling set and makes cutting easier.
- Once thoroughly cooled, lift the bars from the pan using the foil edges and slice into neat squares for serving.
Notes
- Customize Easily swap blueberries with raspberries, blackberries, or mixed berries for delightful flavor variations.
- Make Ahead Prepare the bars a day before serving and store in an airtight container at room temperature for maximum freshness.
- Gluten-Free Option Replace regular flour with gluten-free flour blend and ensure all ingredients are certified gluten-free for sensitive diets.
- Healthier Twist Reduce sugar by using monk fruit sweetener or cut butter quantity to create a lighter, more nutritious breakfast treat.
