Ingredients: Blueberry Crumble Bars
To make these irresistible White Chocolate & Blueberry Crumble Bars, you’ll need the following ingredients. The ingredients are divided into the crust & crumble, the blueberry layer, and the add-ins to give you a complete breakdown of what you’ll need.
For the Crust & Crumble:
- 1 cup (2 sticks / 226 g) unsalted butter, melted
- ¾ cup (150 g) granulated sugar
- ½ cup (100 g) light brown sugar, packed
- 1 tsp vanilla extract
- ½ tsp almond extract (optional, but pairs wonderfully with blueberries)
- 2½ cups (315 g) all-purpose flour
- ¼ tsp baking powder
- ½ tsp salt
For the Blueberry Layer:
- 2½ cups (300 g) fresh or frozen blueberries
- 1 tbsp lemon juice
- 2 tsp lemon zest
- 2 tbsp cornstarch
- ¼ cup (50 g) granulated sugar
Add-ins:
- ¾ cup (125 g) chopped white chocolate or white chocolate chips
Step-by-Step Directions for Preparation Of Blueberry Crumble Bars

Step 1: Preheat & Prep
Preheat your oven to 350°F (175°C) and line a 9×9-inch baking pan (or 23×23 cm) with parchment paper. Leave an overhang for easy removal of the bars once they are done.
Step 2: Make the Crust/Crumble
In a large mixing bowl, whisk together melted butter, granulated sugar, light brown sugar, vanilla extract, and almond extract until smooth. Once well combined, add all-purpose flour, baking powder, and salt into the mixture. Stir until it forms a crumbly texture, but it should hold together when pressed.
Reserve about 1 heaping cup of this crumble mixture for the topping. Press the remaining crumble mixture evenly into the bottom of the prepared pan to form the crust.
Step 3: Make the Blueberry Filling
In another bowl, toss the blueberries with lemon juice, lemon zest, cornstarch, and granulated sugar until evenly coated. Gently fold in the chopped white chocolate or white chocolate chips. This filling will give the bars their sweet and fruity flavor.
Step 4: Assemble the Bars
Spread the blueberry mixture evenly over the crust, ensuring it covers the surface completely. Then, crumble the reserved dough mixture over the blueberry layer. Some parts can be in larger chunks for texture, while others can be smaller for even coverage.
Step 5: Bake
Place the pan into the preheated oven and bake for 35–40 minutes, or until the top turns golden brown and the filling is bubbling around the edges. The aroma will be irresistible!
Step 6: Cool & Serve
Allow the bars to cool completely in the pan, which will take at least 1 hour. This step is important because it helps the bars set and makes them easier to cut. Once they have cooled, cut them into 16 squares.
You can dust them lightly with powdered sugar for an extra touch of sweetness and elegance.
Step 7: Store
Store the bars in an airtight container at room temperature for up to 2 days. You can refrigerate them for up to 5 days or freeze them for up to 2 months. These bars freeze beautifully, so feel free to make a batch ahead of time for later enjoyment.
Tips & Variations
- Frozen Blueberries: If you’re using frozen blueberries, there’s no need to thaw them beforehand. Just add an extra 1 tsp of cornstarch to the filling to help thicken it.
- Richer Flavor: For an extra indulgence, drizzle melted white chocolate over the cooled bars for an added layer of sweetness and richness.
- Mix-Ins: Want to mix things up a bit? You can replace half of the blueberries with raspberries or blackberries for a colorful twist.
- Nutty Option: If you love nuts, try adding ½ cup of sliced almonds or chopped macadamia nuts to the crumble topping for added texture and flavor.
