Step‑by‑Step Instructions for Lemon Blueberry Bars
Step 1: Preheat and Prepare
Begin by preheating your oven to 350°F (175°C). While the oven warms up, line a 9x13 baking dish with parchment paper, allowing some overhang for easy removal later. This ensures your Lemon Blueberry Bars come out perfectly shaped and prevents sticking, setting you up for a successful bake.
Step 2: Whisk the Eggs
In a large mixing bowl, crack three large eggs and whisk them until frothy, about 2 minutes. This step is crucial for incorporating air, which will give your Lemon Blueberry Bars a light texture. The eggs should have a pale yellow color and a slightly bubbly consistency when you're finished.
Step 3: Combine Wet Ingredients
Add 1 ½ cups of granulated sugar, ½ cup of melted butter, ½ cup of fresh lemon juice, 1 tablespoon of lemon zest, 1 teaspoon of vanilla extract, and 1 teaspoon of lemon extract or oil to the whisked eggs. Beat the mixture at medium speed until everything is well blended, yielding a smooth and creamy batter that invites the sunny flavors of lemon.
Step 4: Mix Dry Ingredients
In a separate bowl, combine 2 cups of all-purpose flour with 1 ½ teaspoons of baking powder. Whisk these dry ingredients together until evenly mixed, ensuring that the baking powder is dispersed throughout the flour. This mixture will help your Lemon Blueberry Bars rise beautifully during baking.
Step 5: Combine Wet and Dry Mixtures
Gently stir the flour mixture into the wet ingredients, mixing just until combined. It’s essential not to overmix; you want to see a few flour streaks remaining, which creates that perfect texture for your bars. This step should take around a minute, promoting a moist and tender Lemon Blueberry Bar.
Step 6: Fold in Blueberries
Carefully fold in 1 ½ cups of fresh blueberries, being gentle to avoid breaking them. You should see bursts of juicy blueberries dispersed throughout the batter, creating delightful pockets of flavor. This step allows the blueberries to contribute their sweetness and vibrant color to your Lemon Blueberry Bars.
Step 7: Spread the Batter
Pour the batter into the prepared baking dish, using a spatula to evenly spread it into the corners and smooth the top. The batter should fill the dish uniformly, ensuring even baking. Once you have it just right, it’s time to pop these bars into the oven!
Step 8: Bake
Place your baking dish in the preheated oven and bake for approximately 30 minutes. Keep an eye on the bars; they’re ready when a toothpick inserted in the center comes out clean and the top has a light golden color. The scent of lemon and blueberries will make your kitchen a paradise!
Step 9: Prepare the Glaze
While the bars are baking, prepare the blueberry glaze. In a small saucepan over medium heat, combine ½ cup of blueberries and ½ cup of sugar. Stir frequently until the sugar dissolves and the blueberries burst, creating a glossy sauce, about 5–7 minutes. This delicious glaze will elevate your Lemon Blueberry Bars.
Step 10: Glaze the Bars
Once the Lemon Blueberry Bars are baked to perfection, take them out of the oven and pour the warm blueberry glaze over them while they’re still hot. Use a spatula or spoon to spread the glaze evenly, allowing it to soak in a bit for extra flavor.
Step 11: Cool and Cut
Allow the bars to cool completely in the dish before cutting into squares, about 30–45 minutes. The cooling time helps them set and makes cutting easier, ensuring you have beautiful, neat squares of Lemon Blueberry Bars that are delightful to serve and enjoy!

Zest is Best: Don’t skip the zest: Adding lemon zest intensifies the citrus flavor, giving your Lemon Blueberry Bars an irresistible aroma and taste that will make everyone swoon.

Lemon Blueberry Bars Recipe FAQs
What type of blueberries should I use?
Absolutely! Fresh blueberries are preferred for these Lemon Blueberry Bars. They not only add a burst of flavor but also enhance the visual appeal with their vibrant color. If fresh isn’t available, you can use frozen blueberries, but make sure to thaw and drain them first to avoid excess moisture in the batter.
How long can I store my Lemon Blueberry Bars?
You can store your Lemon Blueberry Bars at room temperature for up to 3 days in an airtight container. If you want to keep them fresh for a longer period, transfer them to the fridge where they’ll last up to a week. Just make sure they are well-covered to avoid drying out.
Can I freeze Lemon Blueberry Bars?
Yes, you can freeze these delightful bars! First, wrap individual squares tightly in plastic wrap, then place them in a freezer bag. They can be frozen for up to 3 months. Whenever you’re ready to enjoy, simply thaw them overnight in the fridge, and they’ll taste as fresh as the day you made them!
What if my Lemon Blueberry Bars are too crumbly?
If you find your bars are too crumbly, it may be due to overmixing the batter. Always mix just until combined—this will help maintain a tender texture. If you're confident in your mixing technique and they still crumble, try adding a little more melted butter next time to help with moisture!
Can I make these bars gluten-free?
Very! To make gluten-free Lemon Blueberry Bars, you can substitute all-purpose flour with a gluten-free blend. Just make sure to choose one that includes xanthan gum, which helps mimic the elasticity you get from wheat flour.
