Blueberry Crumb Bars

Ingredients:

• 3 cups all-purpose flour
• 1/2 cup granulated sugar
• 1/2 cup light brown sugar
• 1/2 teaspoon baking powder
• 1/2 teaspoon baking soda
• 1 cup salted butter, cold and cubed
• 1 large egg
• 2 1/2 cups frozen blueberries, thawed
• 1 teaspoon vanilla extract
• 1/4 cup lemon juice
• 1 tablespoon cornstarch

Instructions:

1. Preheat Oven:
   Preheat oven to 375°F (190°C). Grease or line a 9×13-inch baking dish.
2. Prepare the Crumb Mixture:
   In a large bowl, whisk together flour, granulated sugar, brown sugar, baking powder, and baking soda.
   Add the cold butter cubes and cut into the mixture using a pastry cutter or your hands until it forms pea-sized crumbs.
3. Add the Egg:
   Mix in the egg until the dough starts to come together and is evenly combined.
4. Form the Crust:
   Press about 3/4 of the crumb mixture firmly into the bottom of the prepared baking dish to form an even crust.
5. Prepare the Filling:
   In a separate bowl, combine blueberries, lemon juice, vanilla extract, and cornstarch. Stir until evenly coated.
6. Assemble:
   Spread the blueberry mixture evenly over the crust.
   Sprinkle the remaining crumb mixture over the top.
7. Bake:
   Bake for 40 minutes, or until the top is lightly golden and the filling is bubbling.
8. Cool and Serve:
   Allow the bars to cool for at least 20 minutes before slicing into squares.

Notes

• Cold butter is key for a crumbly texture.
• You can use fresh blueberries instead of frozen.
• For extra flavor, add a little lemon zest to the filling.
• Store in an airtight container at room temperature for up to 2 days or refrigerate for longer freshness.
