Ingredients You’ll Need

The beauty of Lemon Raspberry Bars is how each ingredient plays its part in creating something magical. These familiar staples come together to make a bar that’s soft yet sturdy, sweet but bright, and bursting with gorgeous pink and yellow swirls.

• Raspberries (2 cups, fresh or frozen): Go for fresh when they’re in season for the brightest flavor, but frozen berries work beautifully year-round.
• All-purpose flour (2 1/4 cups): Provides structure and a soft, tender crumb to the shortbread base.
• Granulated sugar (1/2 cup for base, 1 1/2 cups for filling): Sweetness in both layers balances the tartness of raspberries and lemons.
• Corn starch (1 tbsp for base, 1/3 cup for filling): Helps thicken both the base and the lemon raspberry custard for the perfect texture.
• Salt (1/4 tsp): Just the right amount to enhance all the other flavors.
• Unsalted butter (1 cup, melted): Creates a rich, tender, and crumbly foundation for every bar.
• Eggs (6 large): Essential for binding and setting the luscious citrus-berry layer.
• Lemon juice (3/4 cup fresh): Squeezing your own brings vibrant, zesty freshness that bottled versions just can’t match.
• Reduced raspberry puree (1/4 cup from 2 cups berries): Intensifies the raspberry flavor and provides that beautiful pop of pink.

How to Make Lemon Raspberry Bars

Step 1: Create the Raspberry Puree

Start by blending your raspberries until silky smooth, then strain if you want to skip the seeds (trust me, totally worth it for extra elegance). Gently simmer the puree in a saucepan, stirring often, until it thickens and reduces to about 1/4 cup. This step concentrates both the flavor and the color, setting the stage for an unforgettable Lemon Raspberry Bar experience.

Step 2: Make and Bake the Shortbread Base

While your raspberry reduction cools, preheat your oven to 325F and line a 9×13 inch pan with parchment paper, making sure the edges hang over for easy lifting later. Whisk together your dry ingredients, stir in the melted butter, and press the dough firmly into the bottom of your pan. Build up a little lip around the sides so each bar gets the perfect base-to-filling ratio. Bake until the shortbread is set and starting to turn golden, about 20–25 minutes.

Step 3: Prepare the Lemon Raspberry Layer

As the base bakes, whisk sugar and corn starch in a big bowl to banish any lumps. Add the eggs, whisking thoroughly, then pour in the cooled, reduced raspberry puree followed by all that bright, freshly squeezed lemon juice. The mixture will look thin—but that’s exactly what you want for those glossy, vivid custard layers.

Step 4: Assemble and Bake the Bars

Once your shortbread comes out of the oven, give it a gentle prick with a fork (don’t pierce all the way through) to help the filling set evenly. Pour the lemon raspberry mixture over the warm base and pop it back in the oven. Bake until the filling is set and just barely jiggles in the center, about 20–25 minutes. It will firm up even more once chilled.

Step 5: Cool, Chill, and Slice

Cool the bars at room temperature for at least an hour so the custard can settle. For that signature Lemon Raspberry Bar texture, transfer to the fridge and chill at least 2 hours. Lift out the slab using the parchment overhang, and slice into bars with a sharp knife for those pretty layers—wipe your knife between cuts for the most beautiful results!

How to Serve Lemon Raspberry Bars

Garnishes

Embellish your Lemon Raspberry Bars with a dusting of powdered sugar, a few fresh raspberries, or some finely grated lemon zest for a bakery-style finish. If you’re feeling extra, add a sprig of fresh mint to make each bar truly photo-worthy!

Side Dishes

These bars are delightfully rich and tangy, making them shine beside a cup of afternoon tea, a scoop of creamy vanilla ice cream, or even paired with a dollop of freshly whipped cream. Serving them alongside a fresh fruit salad can brighten up any dessert table and complement their vibrant flavors.

Creative Ways to Present

For parties, arrange Lemon Raspberry Bars on a tiered platter with alternating layers of fresh berries. Cut them into triangles or bite-sized squares for elegant dessert buffets, or even wrap them up as edible gifts—everyone loves receiving a little piece of homemade sunshine!

Make Ahead and Storage

Storing Leftovers

Lemon Raspberry Bars keep beautifully in the fridge for up to five days. Store them in an airtight container so they stay tender and fresh. Layer parchment or wax paper between rows if stacking to keep the custard topping neat.

Freezing

If you’d like to make your bars ahead or save a few for later, freeze them! Place cut bars separated by parchment paper in a freezer-safe box. They’ll keep their flavor and texture for up to two months. Thaw them in the refrigerator overnight for the best consistency.

Reheating

These bars are usually enjoyed chilled or at room temperature, so there’s no need to reheat. If you prefer a slightly warmer bite, let them sit out for 10-15 minutes before serving; this brings out the lemony aroma and softens the base just a touch.

FAQs

Can I use bottled lemon juice instead of fresh?

Freshly squeezed lemon juice gives Lemon Raspberry Bars that unmistakable citrus punch and brightness. Bottled juice can work in a pinch, but you’ll miss some of the fresh, zesty flavor that makes these bars so special.

What’s the secret to clean, neat slices?

Be patient! Make sure the bars are thoroughly chilled before slicing. Use a sharp knife, wiping it clean after each cut to keep those layers looking beautiful and bakery-perfect.

Can I use other berries?

Absolutely! Blackberries or mixed berries would be lovely, though the flavor will shift. Adjust the puree as needed, and note that lemon pairs especially well with raspberries for that lively, sweet-tart bite.

Can I make Lemon Raspberry Bars gluten-free?

Yes, simply swap the all-purpose flour for a good-quality gluten-free blend. The texture might be slightly different, but you’ll still get that delicious shortbread base and creamy custard topping!

Do Lemon Raspberry Bars travel well for picnics or potlucks?

They’re fantastic for sharing since they hold together well after chilling. Just keep them in a refrigerator or cooler until serving time to preserve their texture and fresh flavors.
