INGREDIENTS SECTION

Ingredients
For the Crust:
- 2 cups (250 g) all-purpose flour
- 1 cup (2 sticks or 227 g) unsalted butter, room temperature (I recommend using Kerrygold for its rich taste)
- 1/2 cup (100 g) granulated sugar
For the Filling:
- 1 1/2 cups (300 g) granulated sugar
- 1/4 cup (31 g) all-purpose flour
- 4 large eggs, room temperature, beaten (free-range eggs add a wonderful taste!)
- 2/3 cup (163 g) lemon juice, freshly squeezed (I love using organic lemons for a more vibrant flavor)
- 1 1/2 cups (222 g) fresh blueberries (frozen blueberries can work but will slightly alter the texture)
- Confectioners’ sugar for dusting
Notes on Ingredients:
- Ensure your butter is at room temperature for easy blending.
- Fresh lemon juice is non-negotiable for that zesty kick!
- You can substitute the blueberries with other berries or even chopped peaches for a different flavor profile.
STEP-BY-STEP INSTRUCTIONS
Preheat Oven: Preheat your oven to 350 degrees F (175 degrees C). Line a 9×13 inch pan with parchment paper and give it a little spritz with nonstick cooking spray to prevent sticking.
Make the Crust: In a medium-sized bowl, blend the butter, 2 cups of flour, and 1/2 cup granulated sugar using a pastry cutter or fork until crumbly. Press this mixture evenly into the bottom of your prepared pan.
Bake the Crust: Pop the pan in the oven and bake for 23-25 minutes or until the crust is firm and golden, watching carefully to avoid over-browning.
Prepare the Filling: While the crust is baking, whisk together the 1 1/2 cups of granulated sugar and 1/4 cup of flour in a medium bowl. Next, stir in the beaten eggs and freshly squeezed lemon juice until smooth.
Combine and Pour: Once the crust has cooled slightly, pour the lemon filling over the baked crust. Gently sprinkle the fresh blueberries over the filling, taking care to distribute them evenly.
Bake Again: Return the pan to the oven and bake for an additional 28-30 minutes, until the edges are just starting to turn golden, and the center is set but slightly jiggly.
Cool Down: Once done, remove from the oven and let the bars cool at room temperature. Then transfer them to the fridge to chill completely for at least 2 hours. This step is crucial for perfect texture!
Finish Up: Dust the top with confectioners’ sugar just before serving to add an elegant touch. Cut into squares and enjoy!

Chef’s Tips:
- Visual Cues: Look for a firm crust and a filling that’s set yet still has a slight jiggle when you take it out of the oven.
- Common Mistakes: Avoid over-mixing the filling, as this can introduce air bubbles and create cracks in the surface.
EXPERT TIPS & TRICKS
Storage: These bars can be stored in an airtight container at room temperature for up to 2 days, or in the fridge for a week. For longer storage, freeze them for up to 2 months. Just make sure to wrap them well!
Make-Ahead Advice: You can prepare the crust a day in advance and keep it covered until you’re ready to add the filling.
Troubleshooting: If your bars don’t set up properly, they likely need more bake time. Just keep an eye on the edges!
Serving Suggestion: Pair with fresh whipped cream or a scoop of vanilla ice cream for extra indulgence.
Customization: Adding a bit of lemon zest to the filling can enhance the flavor even more!
SERVING SUGGESTIONS
These Lemon Blueberry Bars can stand alone as a delightful treat, but they shine even brighter when served with a side of whipped cream or a scoop of vanilla ice cream. For a summer-inspired picnic, why not pair them with a glass of lemonade or sweet iced tea?
