Tips & Variations
- For extra flavor, add a teaspoon of cinnamon or a zest of lemon to the dough before baking.
- Use frozen blueberries if fresh aren’t available, but do not thaw them before mixing to prevent excess moisture.
- Substitute half the all-purpose flour with whole wheat flour for a nuttier taste and added fiber.
- To make the bars more festive, sprinkle some chopped nuts like pecans or walnuts over the blueberry layer before adding the crumble topping.
Storage
Store the blueberry pie cookie bars in an airtight container at room temperature for up to 3 days or refrigerate for up to a week. Reheat individual bars in the microwave for about 15 seconds to restore softness. They also freeze well for up to 2 months—just thaw before serving.

FAQs
Can I use frozen blueberries instead of fresh?
Yes, frozen blueberries work well. Use them straight from the freezer without thawing to avoid making the filling too watery.
How do I know when the bars are done baking?
The top should be golden brown and a toothpick inserted near the center should come out clean or with just a few moist crumbs attached. Avoid underbaking to keep the bars from being too soft.

Notes
- Using fresh blueberries gives the best flavor and texture, but frozen blueberries can be substituted if fresh are unavailable; thaw and drain excess liquid before use.
- Ensure butter is softened (not melted) to properly cream with sugars for ideal texture.
- Do not overmix the dough once adding the flour to keep bars tender.
- For easier removal, line your baking dish with parchment paper with some overhang.
- These bars keep well in an airtight container at room temperature for up to 3 days or refrigerated for up to a week.
