Blueberry Lattice Bars

Since our area has an annual blueberry festival, my daughters and I are always looking for new berry recipes to enter in the cooking contest. These lovely, yummy bars won a blue ribbon one year. —Debbie Ayers, Baileyville, Maine
  • Total Time
    Prep: 25 min. + chilling Bake: 30 min.
  • Makes
    2 dozen


  • 1-1/3 cups butter, softened
  • 2/3 cup sugar
  • 1/4 teaspoon salt
  • 1 large egg, room temperature
  • 1/2 teaspoon vanilla extract
  • 3-3/4 cups all-purpose flour
  • 3 cups fresh or frozen blueberries
  • 1 cup sugar
  • 3 tablespoons cornstarch


  • Cream butter, sugar and salt until light and fluffy, 5-7 minutes; beat in egg and vanilla. Gradually beat in flour. Divide dough in half; shape each into a 1-in.-thick rectangle. Wrap and refrigerate 2 hours or overnight.
  • Preheat oven to 375°. Place blueberries, sugar and cornstarch in a small saucepan. Bring to a boil over medium heat, stirring frequently; cook and stir until thickened, about 2 minutes. Cool slightly.
  • Roll each portion of dough between 2 sheets of waxed paper into a 14x10-in. rectangle. Place rectangles on separate baking sheets; freeze until firm, 5-10 minutes. Place 1 rectangle in a greased 13x9-in. baking pan, pressing onto bottom and about 1/2 in. up the sides. Add filling.
  • Cut remaining rectangle into 1/2-in. strips; freeze 5-10 minutes to firm. Arrange strips over filling in crisscross fashion. If desired, press edges with a fork to seal strips. Bake until top crust is golden brown, 30-35 minutes. Cool on a wire rack. Cut into bars.

    While this recipe looks delicious and I love blueberries, I'm pretty sure I won't be making this recipe. The name is a minomer judging by the picture. That is not a proper lattice top your showing. A true lattice top alternates going in and out. This one has long sections that don't appear to do that. Hopefully this picture is not of the winning bars, but a misrepresentation. I know lattice crusts are tricky and time consuming, but it really irks me when a lattice top is referenced when its really just strips laid across. I know people disqualified from cooking contests for less, and you let this win a prize.

    TAkes much longer prep time. Lattice dough was impossible to keep in long strips. Had to continually piece it. Probably be easier with a crumble topping. I spent 1 hour 45 minutes from rolling dough until I put in in the oven. Probably another 15 minutes making the dough & preping berries.

    Hi Zirilli - The pan in the picture is a 13x9-in. baking pan, notice how tall the sides of the pan are? We haven't tried this recipe in a larger pan. Sue Stetzel Taste of Home Magazine

    You say 9x13 pan but picture shows a half sheet pan. Did you double the recipe?

    Looks delicious! I am wondering if anyone has tried it with blackberries? I have tons this year and would love to find a new recipe to use them up!

    Pretty good recipe. I used frozen blueberries bc it's winter and they are cheaper but next time I will use fresh and tart blueberries and I think I'll have a better, stronger tasting bar.

    I put some crunchy sugar crystals on the top! They looked so fancy!
