These Lemon Blueberry Crumb Bars are the perfect bright and buttery summer treat. They combine the tangy punch of fresh lemons with the sweet burst of blueberries, all wrapped in a buttery crust and topped with a golden crumble. This is comfort food that feels like home, made with simple ingredients and warm memories.

Ingredients

Scale
  • 2 cups all-purpose flour
  • 1 cup granulated sugar
  • 1 cup cold unsalted butter, cut into cubes
  • 1 teaspoon baking powder
  • 1/4 teaspoon salt
  • 1 large egg
  • 1 teaspoon vanilla extract
  • 2 cups fresh blueberries
  • 1/4 cup lemon juice (about 2 lemons)
  • Zest of 2 lemons
  • 2 tablespoons cornstarch
  • 1/4 cup powdered sugar for dusting

Instructions

  1. Preheat oven to 375 degrees Fahrenheit. Line a 9x13 inch baking pan with parchment paper, leaving overhang on two sides.
  2. In a large bowl, whisk together flour, sugar, baking powder, and salt. Add cold butter cubes and use a pastry cutter or fingers to work butter into flour until mixture resembles coarse crumbs. Reserve 1 cup of this mixture for topping.
  3. To the remaining mixture, add egg and vanilla, stirring until a soft dough forms. Press dough evenly into the bottom of the prepared pan.
  4. In a medium bowl, combine blueberries, lemon juice, lemon zest, and cornstarch. Gently toss until berries are coated. Spread mixture evenly over crust.
  5. Sprinkle reserved crumb mixture over the blueberry layer. Bake for 35 to 40 minutes, until top is golden brown and filling is bubbly.
  6. Let bars cool completely in the pan. Lift out using parchment overhang, dust with powdered sugar, and cut into squares.

Notes

For the flakiest crumb topping, freeze your butter and grate it directly into the flour mixture. You can use frozen blueberries instead of fresh. Store leftovers in an airtight container at room temperature for up to 3 days, or refrigerate for up to a week. Freeze individual bars wrapped tightly for up to 3 months.
