    Lemon Blueberry Bars

    by Patti Estep · Jul 25, 2025

    A close up look at two lemon blueberry bars stacked on top of each other on a white plate.

    These lemon blueberry bars feature a delicious shortbread crust, a tart lemon filling with the addition of fresh blueberries, and are a great dessert to feed a crowd.

    I wanted to bring a treat to my daughter's house for a weekend visit. I knew her boyfriend/partner likes all things citrus, and she loves blueberries, so this lemon blueberry bar would be a good fit.

    We were also meeting my other daughter and her boyfriend/partner there. She loves a good dessert, and he is a vegetarian, so I thought this would be something everyone could enjoy.

    • sugar
    • salt
    • vanilla extract
    • fresh lemon juice
    • lemon zest
    • fresh blueberries

    How to Make Lemon Blueberry Bars

    Step 1. Start by setting the oven to 350 degrees and lining a 9 x 13-inch baking pan with parchment. If you don't have parchment, coat the pan with cooking spray.

    Step 2. Whisk the flour, sugar, and salt together in a large bowl. Then mix in soft butter and vanilla. It should come together to form a dough when you squeeze it in your hands.

    Step 5. Make the filling by beating the eggs in a medium mixing bowl. Add sugar, baking powder, and mix well. Then add the fresh lemon juice and zest. Lastly, fold in the blueberries.

    Blueberry lemon filling poured onto the crust.

    Step 6. Pour the filling onto the cooled crust and bake for 30-40 minutes. Let cool for 30 minutes on the stove or counter. Then refrigerate for 2 hours to firm up.

    I pulled mine out before refrigeration, which wasn't terrible, but they did a lot better after being refrigerated to firm up.

    The taste was soooo good. They had a great flavor: sweet, tart, and refreshing with a buttery shortbread crust.

    This one is a keeper. I'd like to try it with a peach filling next time.
