The middle layer is thick and filled with dark purple, glossy whole blueberries that look juicy and slightly bursting. The top layer is a golden brown crumble topping mixed with oats, giving it a rough and crunchy appearance. The bars are placed on a white marbled surface, and they look fresh and moist.

Ingredients

1 1/2 cups all purpose flour
1/2 cup sugar

Pinch salt
3/4 cup cold butter, cut into cubes

2 eggs
1 cup sugar

1/3 cup all purpose flour
1/2 cup sour cream
Pinch salt

3 cups fresh blueberries

Instructions

Step 1: Preheat your oven to 375°F (190°C) and grease and flour a 9×13 inch baking pan.
Step 2: In a medium bowl, whisk together 1 1/2 cups flour, 1/2 cup sugar, and a pinch of salt. Cut in the cold butter with a pastry cutter or your fingers until the mixture resembles coarse crumbs.

Step 3: Press about two-thirds of the crumb mixture evenly into the bottom of the prepared baking pan to form the crust.
Step 4: In a separate bowl, whisk together 2 eggs, 1 cup sugar, 1/3 cup flour, 1/2 cup sour cream, and a pinch of salt until smooth.
Step 5: Gently fold the fresh blueberries into the filling mixture.

Step 6: Pour the blueberry filling evenly over the crust in the baking pan.
Step 7: Sprinkle the remaining one-third of the crumb mixture evenly over the blueberry filling.
Step 8: Bake for 35-45 minutes, or until the topping is golden brown and the filling is set.

Step 9: Allow the bars to cool completely in the pan before cutting into squares and serving.

Tips & Variations

Use frozen blueberries if fresh are not available; just thaw and drain excess liquid before folding into the filling.
Add a teaspoon of lemon zest to the filling for a bright citrus note.

For a gluten-free option, substitute the all-purpose flour with a gluten-free baking blend.
Serve with whipped cream or vanilla ice cream for an extra special treat.

Storage

Store the blueberry pie bars in an airtight container in the refrigerator for up to 4 days. To reheat, warm individual bars in the microwave for 15-20 seconds or enjoy cold.

How to Serve

The image shows several square blueberry crumble bars placed on a white marbled surface. Each bar has three distinct layers: a light golden brown crumbly base, a thick middle layer of dark purple blueberry filling with visible whole blueberries, and a top layer of golden crumble made of oats and small clumps of dough. The crumble layer adds a rough texture and is evenly spread across the bars. The bars are arranged closely together in the frame, some blurred in the background to create depth.

FAQs

Can I use frozen blueberries instead of fresh?

Yes, you can substitute frozen blueberries. Just make sure to thaw them completely and drain any excess liquid to prevent the filling from becoming too watery.

How do I know when the pie bars are done baking?

The bars are done when the crumb topping is golden brown and the filling is set and no longer jiggly in the center. A toothpick inserted into the filling should come out clean or with only a few moist crumbs.
