Step-by-Step Instructions


Ready to get those sweet blueberry aromas wafting through your kitchen? Follow these simple steps:
- Preheat your oven to 375°F (190°C).
- In a large mixing bowl, whisk together the all-purpose flour, granulated sugar, light brown sugar, baking powder, and baking soda until smooth.
- Using a pastry cutter, work in the cold butter until the mixture resembles small crumbs.
- Add the egg, mixing until fully incorporated into the dough.

- In another bowl, mix thawed blueberries with lemon juice, vanilla extract, and cornstarch until well-coated.
- Pour the blueberry mixture evenly over the crust. Then, sprinkle the reserved crumb mixture on top.
- Bake for about 40 minutes or until the topping is golden brown.
- Let it cool on the counter for about 20 minutes before slicing. Serve and enjoy!
Best Ways to Enjoy It
These blueberry crumb bars can be enjoyed in a variety of ways! Try serving them warm with a scoop of vanilla ice cream or drizzled with a bit of cream or yogurt. Pair them with a steaming cup of tea for afternoon delight, or pack them for a picnic. They also make a delightful breakfast treat when served alongside fresh fruit or a dollop of whipped cream.
Keeping Leftovers Fresh
To keep your blueberry crumb bars in optimal condition, store them in an airtight container at room temperature for up to three days. If you’d like to enjoy them later, simply freeze the bars. Just wrap them tightly in plastic wrap and then in aluminum foil to prevent freezer burn. When you’re ready to indulge, let them thaw in the refrigerator overnight before serving.
Pro Chef Tips
- Butter Temperature: Ensure your butter is cold for that crumbly texture.
- Thaw Blueberries Properly: Drain excess moisture from thawed blueberries to prevent a soggy center.
- Perfect Bake: Use the edge of a toothpick or knife to test for doneness; it should come out clean!
Creative Twists
Want to change things up? Consider adding a touch of almond extract for added flavor, or try incorporating other berries like raspberries or blackberries. If you’re feeling adventurous, swap in some chopped nuts for extra crunch, or drizzle a glaze over the top once they cool for a fun finish.
