What Ingredients You Will Need
This recipe uses simple, fresh ingredients that pack a punch of flavor. Here’s what you’ll need:
- For the Crust:
- 1 cup (125g) all-purpose flour
- 1/4 cup (50g) granulated sugar
- 1/2 cup (115g) unsalted butter, softened
- For the Lemon Filling:
- 3 large eggs
- 1 cup (200g) granulated sugar
- 1/3 cup (80ml) freshly squeezed lemon juice
- 2 tablespoons (15g) all-purpose flour
- Zest of 2 lemons (about 2 teaspoons)
- For the Blueberry Topping:
- 1 cup (150g) fresh blueberries
- 1 tablespoon (15g) granulated sugar
- 1 teaspoon cornstarch
Pro Tip: Use fresh, plump blueberries for the most vibrant flavor. If they’re not in season, frozen blueberries work too—just thaw and drain them first.
Equipment Needed
- 9×9-inch square baking pan
- Mixing bowls (medium and large)
- Whisk
- Rubber spatula
- Microplane or zester
- Measuring cups and spoons
If you don’t have a 9×9-inch pan, you can use an 8×8-inch pan instead—the bars will just be slightly thicker. I’ve tried both, and they turn out great either way!
Preparation Method
- Prepare the crust: Preheat your oven to 350°F (175°C). In a medium mixing bowl, combine the flour, sugar, and softened butter until the mixture forms a crumbly dough. Press the dough evenly into the bottom of your baking pan. Bake for 15 minutes or until lightly golden. Remove from the oven and let it cool slightly.
- Make the filling: In a large mixing bowl, whisk together the eggs and sugar until smooth. Add the lemon juice, flour, and lemon zest, then whisk until fully combined. Pour the mixture over the cooled crust.
- Bake the bars: Return the pan to the oven and bake for 20-25 minutes, or until the filling is set and slightly firm to the touch. Let the bars cool completely before adding the topping.
- Prepare the blueberry topping: In a small saucepan, combine the blueberries, sugar, and cornstarch over medium heat. Cook while stirring until the mixture thickens and the blueberries release their juices (about 5 minutes). Let cool slightly.
- Assemble the bars: Spread the blueberry topping evenly over the cooled lemon filling. Refrigerate the bars for at least 1 hour to set fully.
- Slice and serve: Use a sharp knife to cut into squares or rectangles. Serve chilled or at room temperature.
Pro Tip: For clean slices, wipe your knife with a damp cloth between cuts.
Cooking Tips & Techniques
- Don’t overmix the crust: Keep it crumbly for the perfect texture.
- Use fresh lemon juice: Bottled juice won’t give the same bright flavor.
- Cool before topping: Adding the blueberry topping while the lemon filling is warm can make it runny.
- Chill thoroughly: Refrigerating the bars ensures they hold their shape when sliced.
- Adjust sweetness: If you prefer a sweeter dessert, sprinkle a little powdered sugar over the top before serving.
Variations & Adaptations
- Gluten-Free Version: Swap out the all-purpose flour for a 1:1 gluten-free baking mix.
- Berry Mix Topping: Add raspberries or blackberries along with the blueberries for a colorful twist.
- Vegan Adaptation: Use vegan butter in the crust and replace the eggs with a combination of 1/2 cup silken tofu and 1/4 cup plant-based milk.
Personally, I’ve tried adding a dollop of whipped cream on top for a decadent finish, and let me tell you—it’s a game-changer.
Serving & Storage Suggestions
These Blueberry Lemon Bars are best served chilled, though room temperature works too if you’re in a hurry. Pair them with a cup of tea or a glass of lemonade for the ultimate treat. For a fancy presentation, sprinkle powdered sugar over the top or garnish with a few fresh blueberries and a twist of lemon zest.
Leftovers can be stored in an airtight container in the refrigerator for up to 5 days. If you want to freeze them, wrap individual bars in plastic wrap and store them in a freezer-safe bag for up to 2 months. Thaw in the refrigerator overnight when ready to enjoy.
