Ingredients You’ll Need

This recipe uses a simple yet purposeful list of ingredients that come together to create a delightful medley of flavor and texture. Each element plays a key role – from the buttery shortbread base to the luscious raspberry puree that adds color and fruity charm.

Raspberries (2 cups): Fresh or frozen, they provide the vibrant base for that luscious raspberry puree.
All-purpose flour (2 1/4 cups): The foundation that gives the shortbread base its sturdy yet tender crumb.
Granulated sugar (1/2 cup + 1 1/2 cups): Balances tartness and sweetens both the crust and filling spectacularly.
Corn starch (1 tablespoon + 1/3 cup): Thickens the layers for a perfect consistency without being cakey.
Salt (1/4 teaspoon): Just a pinch to enhance the overall flavor complexity.
Unsalted butter (1 cup, melted): Adds irresistible richness and keeps the crust tender and flavorful.
Large eggs (6): Bind everything together, creating that smooth, custard-like texture in the filling.
Reduced raspberry puree (1/4 cup): Intensifies raspberry flavor and adds a beautiful pink hue to the lemon layer.
Freshly squeezed lemon juice (3/4 cup): The star citrus element that gives the bars their fresh, tangy kick.

How to Make Lemon Raspberry Bars

Step 1: Prepare the Raspberry Puree

Start by blending the raspberries until smooth, then gently strain them to remove seeds for a silkier texture. Next, simmer the puree on low-medium heat until it thickens and reduces to a concentrated quarter cup or so. This step is crucial for elevating the raspberry flavor while ensuring the filling isn’t watery, giving those Lemon Raspberry Bars that luscious, vibrant filling you’re dreaming of.

Step 2: Make the Shortbread Base

Preheat your oven to 325°F (160°C), and line a 9×13 inch pan with parchment paper to make lifting the bars easier later. Whisk together flour, sugar, corn starch, and salt, then stir in the melted butter until a thick dough forms. Press this mixture firmly into the pan, creating a slight lip around the edges to hold the luscious filling that comes next. Bake for 20-25 minutes until it’s just lightly golden and set—the perfect sturdy base for your Lemon Raspberry Bars.

Step 3: Create the Lemon Raspberry Layer

While the crust is baking, whisk together sugar and cornstarch in a large bowl to eliminate lumps, then gradually mix in the eggs. Stir in the cooled reduced raspberry puree followed carefully by the freshly squeezed lemon juice. The combination might look runny, but once baked, it sets into a beautifully smooth, tangy, and fruity layer. Pour this mixture over the warm shortbread base, then return to the oven for another 20-25 minutes until set and slightly firm to the touch.

Step 4: Cool and Chill the Bars

Once out of the oven, allow the bars to cool completely at room temperature, ideally for about an hour. Then cover them and refrigerate for a minimum of two hours to fully set. This chilling step intensifies the flavors and ensures those Lemon Raspberry Bars slice neatly and hold their structure perfectly.

How to Serve Lemon Raspberry Bars

Garnishes

Adding a light dusting of powdered sugar before serving adds just a touch of sweetness and a beautiful finish to these bars. For an extra pop of color and texture, scatter a few fresh raspberries or a thin slice of lemon on each piece. This little extra makes every bite feel like a special occasion.

Side Dishes

Lemon Raspberry Bars shine alongside a dollop of whipped cream or a scoop of creamy vanilla ice cream. Their cool, smooth textures balance perfectly with the tangy bars. For a brunch or afternoon treat, serve with a cup of herbal tea or a glass of sparkling lemonade to echo and complement the citrus notes.

Creative Ways to Present

For an impressive dessert platter, arrange the Lemon Raspberry Bars on a rustic wooden board garnished with edible flowers or fresh mint leaves. Alternatively, cut the bars into mini squares for bite-sized treats perfect for parties. Layering them in clear glass jars with whipped cream for individual servings is another fun and elegant option.

Make Ahead and Storage

Storing Leftovers

Keep any leftover Lemon Raspberry Bars tightly wrapped in plastic or stored in an airtight container in the refrigerator. They’ll stay deliciously fresh for up to 4 days, allowing you to enjoy that bright, fruity taste whenever a craving hits.

Freezing

If you want to make these bars in advance, feel free to freeze them. Wrap individual slices well in plastic wrap, then place them in a freezer-safe container or bag. When stored properly, they maintain their flavor and texture for up to 3 months. Just thaw them in the refrigerator overnight before enjoying.

Reheating

While Lemon Raspberry Bars are best served chilled, if you prefer a slightly warmed treat, pop a slice in the microwave for 10-15 seconds. This softens the bars just enough but doesn’t compromise the flavor or texture. Alternatively, enjoy them straight from the fridge for that refreshing burst of bright citrus and raspberry.

FAQs

Can I use frozen raspberries for the puree?

Yes, frozen raspberries work wonderfully for this recipe. Just thaw them first and strain out any excess juice if it seems too watery before reducing. This helps maintain the intense raspberry flavor without diluting your filling.

Do I need to remove raspberry seeds?

Removing seeds is optional, but it does make the texture of the lemon raspberry layer much smoother and more refined. Using a fine mesh sieve or sifter to strain out seeds after blending gives the bars a professional finish.

Can I substitute fresh lemon juice with bottled lemon juice?

Freshly squeezed lemon juice is highly recommended for the best bright and natural flavor, but if you must, bottled lemon juice can be used in a pinch. Just be aware that the brightness and tartness might be slightly muted.

How should I cut the bars for neat slices?

Using a sharp knife, wipe it clean between cuts to prevent smearing. Lifting the bars from the pan with the parchment paper overhang helps to avoid sticking. Chill the bars thoroughly before slicing to ensure clean edges.

Can these bars be made gluten-free?

To make gluten-free Lemon Raspberry Bars, try substituting the all-purpose flour with a gluten-free baking blend that measures cup-for-cup. Keep in mind the crust texture might vary slightly, but the delicious flavor will absolutely shine through.
