Here's everything you need to make these Fresh Lemon Raspberry Bars.
See Recipe Card Below This Post For Ingredient Quantities
Shortbread Base:
Granulated sugar: Sweetens the crust and helps create that tender, crumbly texture.
Lemon zest: Rubbed into the sugar, this releases fragrant oils and adds a subtle citrus note to the base. Save the juice for the filling.
Unsalted butter, softened: Creates the rich, buttery foundation of the shortbread. Make sure it's soft so it creams smoothly.
Pure vanilla extract: Adds warmth and depth to the crust.
Sea salt: Balances the sweetness and brings out all the other flavors.
All-purpose flour: Forms the structure of the shortbread and gives it that classic, sandy texture.
Raspberry Lemon Filling:
Lemon zest: Another dose of bright citrus flavor that makes the filling sing. Use the zest from two lemons here.
Granulated sugar: Sweetens the filling and helps it set properly as it bakes.
All-purpose flour: Thickens the filling so it's creamy and custardy, not runny.
Large eggs: Bind everything together and give the filling that smooth, rich texture.
Salt: Just a pinch to balance the sweetness and enhance the lemon flavor.
Raspberries, packed: Fresh or frozen work beautifully. You'll mash and strain them to get a smooth, vibrant puree.
Freshly squeezed lemon juice: The star of the filling. Use juice from two to three lemons for the best flavor.
Powdered sugar: Dusted on top just before serving for a pretty finish.
HOW TO MAKE Lemon Raspberry Bars
Follow these steps to make perfect Lemon Bars with Raspberry Filling every time.
Shortbread Base:
Preheat and prep: Preheat your oven to 355°F (180°C). Grease an 8-inch square baking pan and line it with parchment paper, leaving a few inches of overhang on the sides so you can lift the bars out easily later.
Combine sugar and zest: In a large bowl, add the granulated sugar and lemon zest. Use your fingers to rub them together until the mixture looks moist and smells incredible. This step releases all those lovely citrus oils.
Cream the butter: Add the softened butter to the lemon-sugar mixture. Beat with an electric mixer until smooth and creamy, about two to three minutes. Scrape down the sides of the bowl as needed. Mix in the vanilla extract and salt until combined.
Add the flour: Sift in the all-purpose flour and gently fold it in with a spatula until no dry streaks remain. Don't overmix, or the crust will get tough.
Press and bake: Press the dough evenly into the prepared pan, making sure to create a thin border along the sides. Bake for 22 to 24 minutes, until the edges turn golden brown and the top is no longer shiny. The crust should look set but not overly dark.
Raspberry Lemon Filling:
Mix sugar and zest: In a large non-metal bowl, combine the granulated sugar and lemon zest. Rub them together until fragrant. Add the flour and whisk well to break up any lumps.
Add eggs: Crack in the eggs and add the salt. Whisk gently by hand until the mixture is smooth. Try not to whisk too hard, or you'll create air bubbles that show up in the finished bars.
Prepare the raspberry puree: Mash the raspberries with a fork until they're broken down. Strain them through a fine-mesh sieve to remove the seeds, pressing gently to extract about 1⁄4 cup of smooth puree. Add the raspberry puree and lemon juice to the egg mixture, stirring gently to combine.
Pour over hot crust: As soon as the crust comes out of the oven, pour the filling on top. Use a toothpick or kitchen torch to smooth out any bubbles that rise to the surface.
Bake the filling: Return the pan to the oven and bake for 18 to 20 minutes, until the edges are set and the center has just a slight wiggle. The filling shouldn't look liquid.
Cool and chill: Let the bars cool at room temperature for about two hours. Then transfer them to the fridge and chill for at least one more hour. This helps the filling set completely.
Finish and serve: Once the bars are fully chilled, lift them out of the pan using the parchment paper overhang. Dust the top with powdered sugar just before serving. Cut into squares with a sharp knife, wiping the blade clean between cuts for the neatest slices. Serve chilled or at room temperature.
Substitutions and Swaps
No fresh raspberries? Frozen raspberries work just as well. Thaw them completely and strain to get the puree.
Out of lemons? You can use bottled lemon juice in a pinch, but fresh lemon juice and zest give you the best flavor.
Want a different berry? Blackberries or strawberries can replace the raspberries. Just make sure to strain them well to remove seeds.
Gluten-free? Swap the all-purpose flour with a 1:1 gluten-free baking blend in both the crust and the filling.
Dairy-free crust? Use vegan butter or coconut oil in place of regular butter. The texture will be slightly different but still delicious.
Equipment FOR Lemon Raspberry Bars
8-inch square baking pan: The right size for these bars. A 9-inch pan will make them thinner.
Parchment paper: Lines the pan and makes lifting the bars out easy.
Stand mixer or hand mixer: Creams the butter and sugar quickly and smoothly.
Sifter: Helps you avoid lumps in the flour.
Whisk: Mixes the filling gently without creating too many air bubbles.
Toothpick: Useful for popping any bubbles in the filling before baking.
Sieve: Strains the raspberries to remove seeds and give you a smooth puree.
Storage Tips
Room temperature: These Lemon Raspberry Bars can sit at room temperature for about two hours, but they're best kept chilled.
In the fridge: Store the bars in an airtight container in the fridge for up to five days. The filling stays creamy and the crust keeps its texture.
In the freezer: Wrap individual Lemon Raspberry Bars in plastic wrap, then place them in a freezer-safe container. Freeze for up to two months. Thaw in the fridge overnight before serving.
Serving tip: Dust with powdered sugar just before serving, not before storing, or it will absorb into the Lemon Raspberry Bars.
Expert Tips
Use room-temperature butter: Softened butter creams better with the sugar and gives you a tender crust.
Don't skip the zest: Rubbing the Lemon Raspberry Lemon Raspberry Bars zest into the sugar releases essential oils and gives you way more flavor than zest alone.
Strain the raspberries well: Seeds in the filling aren't fun to bite into, so take the time to strain them properly.
Pour filling on a hot crust: This helps the filling adhere to the base and bake evenly.
Let them chill completely: The filling needs time to set. Cutting them too early will leave you with a mess.
Wipe your knife: For clean slices, wipe the blade with a damp towel between each cut.
FAQ
Do lemon bars go in the fridge or counter?
Lemon bars should be stored in the fridge. The filling is egg-based, so keeping them chilled keeps them fresh and safe to eat. You can leave them at room temperature for a couple of hours while serving, but pop them back in the fridge after that. In our house, we keep them chilled and just pull them out about 10 minutes before serving so they're not too cold.
Should Lemon Raspberry Bars be jiggly when done?
Yes, lemon bars should have a slight jiggle in the center when you take them out of the oven. The edges will look set, but the middle should wobble just a little. As they cool, the filling firms up. If you bake them until they're completely solid in the oven, they'll end up overcooked and rubbery. My mom always told me, "When in doubt, underbake a little." She was right.
How long do Lemon Raspberry Bars need to set?
Lemon Raspberry Bars need at least two to three hours to set properly. I usually let mine cool at room temperature for two hours, then chill them in the fridge for another hour or two. This gives the filling time to firm up so you can cut clean slices. If you're in a hurry, you can pop them in the fridge right after they cool for about 20 minutes, but the longer they chill, the better they slice.
Do raspberry bars need to be refrigerated?
Yes, Lemon Raspberry Bars with a custard-style filling like this one need to be refrigerated. The eggs and dairy in the filling can spoil if left out too long. Store them in an airtight container in the fridge, and they'll stay fresh for up to five days. If you're bringing them to a party, keep them chilled until just before serving.
