Ingredients You’ll Need
The beauty of this Lemon Blueberry Shortbread Bars Recipe lies in its simplicity and how each ingredient plays an essential role in creating the perfect harmony of flavors and textures. Every item is straightforward yet crucial, ensuring delightful taste and a gorgeous appearance that pops.
- Unsalted butter: 1 cup, softened to bring a rich, creamy texture that’s fundamental for authentic shortbread.
- Granulated sugar: 1 cup, to add the right measure of sweetness and help create a beautifully tender crumb.
- Vanilla extract: 1 teaspoon, lending a subtle warmth that enhances the overall flavor without overpowering.
- Lemon zest: Zest of 1 lemon, packing in a punch of bright citrus that gives the bars their signature zing.
- All-purpose flour: 2 cups, the base that provides the structure and buttery crunch of the shortbread.
- Salt: 1/4 teaspoon, to balance out sweetness and elevate the other flavors.
- Fresh blueberries: 1 cup, juicy bursts that introduce natural fruitiness and pretty specks of color throughout the bars.
How to Make Lemon Blueberry Shortbread Bars Recipe
Step 1: Prepare Your Oven and Pan
Start by preheating your oven to 350 degrees Fahrenheit (175 degrees Celsius). Lightly grease a 9 by 13-inch baking pan to ensure your bars don’t stick and come out with perfectly clean edges. This simple prep step is key for smooth baking and easy cutting later on.
Step 2: Cream Butter and Sugar
In a large mixing bowl, cream together the softened unsalted butter and granulated sugar until the mixture is light and fluffy. This process aerates the dough, ensuring the bars will have a tender yet crumbly texture with just the right hint of sweetness.
Step 3: Add Vanilla and Lemon Zest
Next, stir in the vanilla extract along with the freshly grated lemon zest. This step packs the dough with aroma and a refreshing citrus note that’s truly the heart of this recipe.
Step 4: Combine Dry Ingredients
In a separate bowl, whisk together the all-purpose flour and salt. Mixing these dry ingredients ensures an even distribution of salt and prevents clumps, providing a consistently smooth dough.
Step 5: Mix Dry Ingredients into Wet
Gradually add the flour mixture to the butter and sugar, folding it gently until just combined. Avoid overmixing to preserve a tender shortbread texture that crumbles delicately after baking.
Step 6: Fold in Fresh Blueberries
Carefully fold in the fresh blueberries without crushing them. Their juicy bursts will soften slightly during baking, infusing the bars with pockets of sweet, fruity flavor that contrast beautifully with the citrus and buttery base.
Step 7: Spread and Bake
Spread the dough evenly into your prepared baking pan, smoothing out the surface with a spatula. Bake the bars for 25 to 30 minutes, or until the edges turn a lovely golden brown and a toothpick inserted in the center comes out clean. The aroma at this stage is absolutely irresistible!
Step 8: Cool and Cut
Allow the bars to cool completely in the pan before slicing them into twelve squares. Cooling helps the shortbread set firmly so each bar holds its shape perfectly when served.
How to Serve Lemon Blueberry Shortbread Bars Recipe

Garnishes
Add a light dusting of powdered sugar or a thin drizzle of lemon glaze on top to elevate the presentation and introduce an extra touch of sweetness. Fresh lemon slices or a few blueberries on the side also make these bars look as delightful as they taste.
Side Dishes
These shortbread bars pair wonderfully with a scoop of vanilla ice cream or a dollop of freshly whipped cream. A cup of hot tea or a glass of iced lemonade complements the citrus and berry notes perfectly, rounding out your dessert experience.
Creative Ways to Present
Try cutting the bars into bite-sized squares and serving them on a colorful platter with edible flowers for a stunning spring or summer centerpiece. Alternatively, layer pieces in a clear dessert dish with whipped cream and fresh blueberries for a casual parfait that’s just as delicious.
Make Ahead and Storage
Storing Leftovers
Keep any leftover Lemon Blueberry Shortbread Bars Recipe squares stored in an airtight container at room temperature for up to three days. This keeps them fresh and perfectly crumbly, ready to enjoy whenever a sweet craving hits.
Freezing
If you want to save these treats for later, freeze the bars by wrapping them tightly in plastic wrap and placing them in a freezer-safe container for up to one month. Thaw at room temperature before serving to preserve the texture and flavor.
Reheating
For a warm twist, gently reheat the bars in a low oven (around 300 degrees Fahrenheit) for 5-7 minutes. This softens the shortbread slightly without melting the berries, reviving that fresh-baked magic.
FAQs
Can I use frozen blueberries instead of fresh?
While fresh blueberries are preferred for the best texture and flavor, frozen berries can be used if fresh aren’t available. Just make sure to thaw and drain them well to avoid adding extra moisture to your dough.
Is it possible to make these bars gluten-free?
Yes! Substitute the all-purpose flour with a gluten-free baking blend designed for shortbread or cookies. The texture might be slightly different, but the bars will still be delicious.
Can I add other fruits instead of blueberries?
Absolutely! Raspberries, blackberries, or even diced strawberries can make fantastic alternatives. Just be mindful of the moisture content and gently fold them in as you would with the blueberries.
How long do these bars last once baked?
When stored properly in an airtight container, the Lemon Blueberry Shortbread Bars Recipe will stay fresh for up to three days at room temperature. Beyond that, they may start to dry out.
What’s the best way to cut the bars without crumbling?
Use a sharp knife and wait until the bars are fully cooled before cutting. Wiping the knife clean between cuts will help maintain neat edges without crumbling.
