Homemade Lemon Blueberry Bars

There’s something so comforting about the bright tang of lemon paired with the sweet burst of blueberries, all nestled in a buttery crust. These lemon blueberry bars are like sunshine on a plate—perfect for afternoon tea, a summer picnic, or just because you deserve a little treat. Let’s gather our ingredients and bake up some happiness!

Ingredients You’ll Need

• 1 cup (2 sticks) unsalted butter, softened – The foundation of our crumbly, buttery crust. If you forget to soften it, a quick 10-second zap in the microwave will do the trick—just don’t let it melt!
• 2 cups all-purpose flour – The trusty backbone of our crust. For a slightly nuttier flavor, you could swap half for almond flour.
• ½ cup granulated sugar – Just enough sweetness to balance the tartness of the lemon.
• ¼ teaspoon salt – A pinch to enhance all the flavors.
• 4 large eggs – Room temperature is best for even mixing. If you’re in a hurry, soak them in warm water for 5 minutes.
• 1 ½ cups granulated sugar – Yes, more sugar! This sweetens the luscious lemon filling.
• ½ cup fresh lemon juice (about 3-4 lemons) – Roll your lemons on the counter before juicing to get the most out of them. And zest them first—you’ll need it later!
• 1 tablespoon lemon zest – This is where the magic happens. The zest packs an extra punch of citrusy brightness.
• ½ cup all-purpose flour – This helps thicken the filling so it sets perfectly.
• 1 ½ cups fresh blueberries – If fresh aren’t in season, frozen work too—just don’t thaw them, or they’ll bleed too much juice.
• Powdered sugar (for dusting) – The finishing touch that makes these bars look as dreamy as they taste.

Step-by-Step Instructions

1. Preheat & Prep: Start by preheating your oven to 350°F (175°C). Line a 9×13-inch baking pan with parchment paper, leaving some overhang on the sides. This little trick makes lifting the bars out a breeze later!

2. Make the Crust: In a large bowl, cream together the softened butter and ½ cup sugar until light and fluffy. Gradually mix in the flour and salt until the dough comes together. It should feel like wet sand—press it firmly into the bottom of your prepared pan. Bake for 15-20 minutes, just until the edges turn golden. Your kitchen will smell like buttery heaven.

3. Whisk the Filling: While the crust bakes, whisk the eggs, 1 ½ cups sugar, lemon juice, and zest in a bowl until smooth. Gently stir in the flour—don’t overmix, or the filling might become tough.

4. Add the Berries: Once the crust is ready, sprinkle the blueberries evenly over the top. Slowly pour the lemon filling over the berries, letting it seep into all the nooks and crannies.

5. Bake to Perfection: Return the pan to the oven and bake for another 25-30 minutes. The filling should be set with just the slightest jiggle in the center. Too much wobble? Give it a few more minutes. Too firm? You might have overbaked—but don’t worry, they’ll still taste amazing.

Conclusion

These Homemade Lemon Blueberry Bars are the perfect balance of tangy and sweet, with a buttery crust and a luscious fruit filling. Whether you’re baking for a summer picnic, a family gathering, or just treating yourself, this recipe is sure to impress.

FAQs

Can I use frozen blueberries instead of fresh?

Absolutely! Frozen blueberries work just as well in this recipe. Just be sure to thaw and drain them first to avoid excess moisture in the filling.

How long do these bars stay fresh?

Stored in an airtight container in the refrigerator, these bars will stay fresh for up to 4 days. You can also freeze them for up to 2 months—just thaw before serving!

Can I substitute the lemon with another citrus fruit?

Yes! Lime or orange zest and juice can be used for a fun twist. The bars will still have that bright, citrusy flavor, just with a slightly different profile.

Why is my crust crumbly?

If your crust is too crumbly, it might need a bit more butter. Make sure the mixture holds together when pressed—if it doesn’t, add another tablespoon of melted butter.

Can I make these gluten-free?

Definitely! Swap the all-purpose flour for a gluten-free 1:1 baking blend, and ensure your other ingredients (like oats, if used) are certified gluten-free.
