Ingredients You’ll Need

Gathering these ingredients is a breeze, and each one plays an important role in bringing out the unique taste, texture, and color that make Lemon Raspberry Bars so special.

• Raspberries (2 cups): Fresh or frozen, these bring vibrant red color and natural sweetness, with a little tartness.
• All-purpose flour (2 1/4 cups): The sturdy foundation for the buttery shortbread crust.
• Granulated sugar (1/2 cup and 1 1/2 cups): Sweetness to balance the tart lemon and raspberries, split between crust and filling.
• Corn starch (1 tbsp and 1/3 cup): Adds structure and thickness to the crust and luscious lemon raspberry filling.
• Salt (1/4 tsp): Enhances all the flavors without stealing the spotlight.
• Unsalted butter (1 cup, melted): The rich, creamy component that gives the crust its tender, melt-in-your-mouth texture.
• Large eggs (6): Helps to bind ingredients and create a smooth filling with perfect consistency.
• Reduced raspberry puree (1/4 cup): Intensifies raspberry flavor with concentrated sweetness and color.
• Freshly squeezed lemon juice (3/4 cup): Provides a zesty, citrusy punch that brightens the entire bar.

How to Make Lemon Raspberry Bars

Step 1: Preparing the Raspberry Puree

Start by pulsing two cups of raspberries in a blender or food processor until smooth. For an extra smooth filling without seeds, push the puree through a fine mesh strainer. Next, gently simmer the seedless puree in a saucepan to reduce its liquid, concentrating the raspberry flavor. This takes about 15 to 20 minutes and ends with roughly ¼ cup of thick, vibrant puree, the secret ingredient that brings the raspberry magic to life in your bars.

Step 2: Making the Shortbread Base

Preheat your oven to 325°F (160°C) and prepare a 9×13 inch pan with parchment paper, leaving an overhang for easy removal. Whisk together the flour, sugar, corn starch, and salt in a bowl—this dry mix is the backbone of your shortbread. Stir in melted unsalted butter until you get a thick dough. Press this mixture evenly into the pan, creating a slight lip around the edges. Bake for about 20-25 minutes until it’s set and lightly golden. This crust is buttery and crisp, perfectly balancing the soft lemon raspberry topping.

Step 3: Crafting the Lemon Raspberry Filling

While the crust bakes, whisk together the sugar and corn starch to ensure no lumps remain. Then add the eggs, whisking until smooth. Next, blend in the cooled reduced raspberry puree, followed carefully by the fresh lemon juice. This results in a glossy, liquidy batter ready to be poured over the baked crust. After removing the crust from the oven (don’t forget to gently prick its surface with a fork to prevent bubbling), pour the vibrant lemon raspberry mixture on top and bake again for 20-25 minutes, until the filling is set with a slight jiggle.

Step 4: Cooling and Slicing

Once out of the oven, allow the bars to cool completely at room temperature for at least an hour. Then chill in the fridge for at least two more hours—this step helps the bars firm up for clean, beautiful slices. Use the parchment paper overhang to lift the bars neatly from the pan and slice with a sharp knife, wiping it clean between cuts to maintain those crisp edges. Now your Lemon Raspberry Bars are ready to dazzle!

How to Serve Lemon Raspberry Bars

Garnishes

Adding a gentle sprinkle of powdered sugar or a few fresh raspberries on top instantly elevates these bars. A few small lemon zest curls add a pop of color and amplify the bright citrus flavor. These simple touches make serving your bars feel extra special and inviting.

Side Dishes

Lemon Raspberry Bars pair beautifully with a dollop of whipped cream or a scoop of vanilla ice cream for a creamy contrast. If you want something lighter, try serving alongside a fresh berry salad or a hot cup of herbal tea to complement the bars’ fruity brightness.

Creative Ways to Present

For parties, arrange the Lemon Raspberry Bars on colorful platters or tiered trays for eye-catching dessert tables. Try serving individual bars in mini cupcake liners to keep portions neat. You can even drizzle some melted white chocolate over the top for a decorative and indulgent twist.

Make Ahead and Storage

Storing Leftovers

Keep your Lemon Raspberry Bars fresh by storing them in an airtight container in the refrigerator. They stay delicious for up to 4 days, making them a convenient treat to enjoy throughout the week whenever a lemony bite is calling your name.

Freezing

You can freeze these bars if you want to stash extras for later. Wrap them tightly in plastic wrap and then aluminum foil or place them in a freezer bag. Freeze for up to 3 months. Thaw in the fridge overnight before serving for the best texture and flavor.

Reheating

While these bars are delightful chilled, if you prefer a warm serving, gently heat them in the oven at 300°F (150°C) for 5-7 minutes. Keep an eye on them so they don’t dry out. Warming slightly enhances the aroma and softens the texture, perfect for cozy moments.

FAQs

Can I use frozen raspberries for the Lemon Raspberry Bars?

Absolutely! Frozen raspberries work just as well. Just thaw them first and drain any excess juice before blending to ensure your puree has the right consistency.

Is it necessary to reduce the raspberry puree?

Reducing the puree intensifies its flavor and thickens the mixture so that your filling isn’t too runny. While optional, it’s highly recommended for the best texture and taste.

Can I make these lemon raspberry bars vegan?

These bars rely on eggs and butter for structure and texture, so substituting those can be tricky. For a vegan version, you’d need specialized egg replacers and plant-based butters, which may alter the final result significantly.

How do I get clean slices for serving?

Use a very sharp knife and wipe it clean between cuts to prevent the filling from sticking and tearing. Chilling the bars well before slicing also helps maintain those perfect edges.

Can I adjust the lemon or raspberry flavor intensity?

Yes! For a stronger lemon kick, add a bit more fresh lemon juice or zest. To boost raspberry flavor, increase the amount of puree slightly or add small fresh raspberries on top before baking.
