How To Make Blueberry Pie Oatmeal Crumble Bars

Step 1: Prepare Baking Setup

Grab a 9×13-inch baking pan and line it with parchment paper, letting the edges hang over for easy bar removal. Warm up the oven to a cozy 350°F.

Step 2: Create Blueberry Filling

• Granulated sugar
• Cornstarch
• Lemon juice

Gently mix everything so the berries get a delicious sweet coating. Let the mixture sit and get juicy.

Step 3: Mix Crumble Base

• Rolled oats
• All-purpose flour
• Brown sugar
• Baking powder
• Salt

Step 4: Create Crumbly Texture

Take cold butter and break it into the dry ingredients. Use your fingers or a pastry cutter to mix until the mixture looks like sandy, coarse crumbs.

Step 5: Add Binding Ingredients

Whisk together egg and vanilla extract. Pour this mixture into the crumble and stir until the ingredients just come together with a slightly clumpy texture.

Step 6: Build First Layer

Press about two-thirds of the crumble mixture firmly into the prepared pan. Make sure you create an even, solid base layer.

Step 7: Add Blueberry Layer

Spread the macerated blueberry filling evenly across the crumble base. Cover every inch with the juicy fruit mixture.

Step 8: Top with Remaining Crumble

Sprinkle the remaining crumble mixture over the blueberries. Dust ground cinnamon on top for extra warmth and flavor.

Step 9: Bake to Perfection

Slide the pan into the oven and bake for 40-45 minutes. Look for a golden brown top and bubbling blueberry edges.

Step 10: Cool and Set

Remove from the oven and let the bars cool completely in the pan. This takes about 2 hours and helps them set properly.

Step 11: Serve and Enjoy

Lift the bars out using the parchment paper overhang. Slice into delightful squares and serve to eager friends and family.

Top Tips For Blueberry Pie Oatmeal Crumble Bars

• Seal Blueberry Moisture: Let macerated blueberries sit for 15-20 minutes to release juices and intensify flavors before spreading on the base.
• Prevent Soggy Bottom: Pat blueberries slightly dry with paper towels to reduce excess liquid and maintain a crisp crumble crust.
• Enhance Crumble Texture: Chill the butter-oat mixture for 10 minutes before pressing into the pan to create a more defined, crumbly texture.
• Control Sweetness Levels: Adjust sugar quantities based on blueberry ripeness – less sugar for sweet berries, more for tart varieties.
• Store Smart: Keep bars in an airtight container at room temperature for 3 days or refrigerate for up to 5 days, maintaining their delicious crumbly consistency.

How To Store Blueberry Pie Oatmeal Crumble Bars Well

• Store cooled blueberry oatmeal crumble bars in an airtight container in the refrigerator for up to 5 days. Separate layers with parchment paper to prevent sticking.
