What You’ll Need

• 120g (1 cup) All-Purpose Flour (for crust): Provides the structure for our buttery shortbread crust. Using all-purpose flour ensures a tender, yet firm base for the tangy lemon filling.
• 30g (¼ cup) Powdered Sugar (for crust): Also known as confectioners’ sugar, this adds a subtle sweetness to the crust and contributes to its delicate texture. It dissolves easily, creating a smooth and refined crumb.
• 115g (½ cup) Unsalted Butter, cold and cubed (for crust): The key to a flaky and tender crust! Keeping the butter cold is crucial; it creates pockets of fat that melt during baking, resulting in a beautifully layered texture.
• Pinch of Salt (for crust): Enhances the flavors of the crust and balances the sweetness. A small amount of salt is essential for a well-rounded taste.
• 150g (1 cup) Fresh Raspberries: These provide the beautiful swirl and fruity counterpoint to the lemon. Fresh raspberries are best for their vibrant flavor and color, but frozen (thawed and drained) can be used in a pinch.
• 30g (¼ cup) Granulated Sugar (for raspberry swirl): Sweetens the raspberries and helps create a smooth puree.
• 1 tbsp (15ml) Fresh Lemon Juice (for raspberry swirl): Brightens the raspberry flavor and adds a touch of acidity.
• 200g (1 cup) Granulated Sugar (for lemon filling): The primary sweetener for the lemon filling, providing a classic sweetness that complements the tartness of the lemon juice.
• 60ml (¼ cup) Fresh Lemon Juice (for lemon filling): The star of the show! Freshly squeezed lemon juice is essential for the bright, zesty flavor of these bars. Bottled juice simply won’t deliver the same vibrant taste.
• Zest of 2 Lemons (≈2 tsp): Adds an intense lemon aroma and flavor to the filling. Be sure to zest only the yellow part of the peel, avoiding the bitter white pith.
• 4 Large Eggs: Bind the lemon filling together and contribute to its rich, creamy texture.
• 30g (¼ cup) Unsalted Butter, melted (for lemon filling): Adds richness and moisture to the lemon filling, creating a smooth and velvety texture.
• 20g (2 tbsp) All-Purpose Flour (for lemon filling): Helps to thicken the lemon filling and provide structure.
• 80g (⅔ cup) Almond Flour: Forms the base of the crumb topping, lending a delicate nutty flavor and a slightly coarser texture.
• 40g (¼ cup) Granulated Sugar (for almond crumb topping): Sweetens the almond crumb topping and helps it to caramelize during baking.
• 30g (¼ cup) Sliced Almonds, toasted: Adds crunch and a beautiful visual appeal to the crumb topping. Toasting the almonds enhances their flavor and texture.
• 30g (¼ cup) Unsalted Butter, melted (for almond crumb topping): Binds the crumb topping ingredients together and creates a golden-brown, crispy texture.
• Powdered Sugar (for dusting): A final touch of sweetness and elegance, adding a delicate dusting of white to the finished bars.
• A few Fresh Raspberries (for garnish): Adds a pop of color and reinforces the raspberry flavor.
• Optional: Small Mint Leaf (for garnish): Provides a fresh, aromatic garnish and a beautiful contrast to the bright colors of the bars.

Substitutions & Variations

While this recipe is perfect as is, feel free to make a few adjustments to suit your preferences! If you don’t have almond flour, you can substitute it with an equal amount of all-purpose flour, though the almond flavor will be lost. For a different fruit swirl, try strawberry or blueberry puree. If you’re not a fan of toasted almonds, you can use other nuts like pecans or walnuts in the crumb topping.

Detailed Step-by-Step Instructions for Perfect Lemon Bars

1. Prepare the Pan & Preheat: Begin by preheating your oven to 175°C (350°F). This ensures even baking. Line an 8×8 inch square pan with parchment paper, allowing for an overhang on all sides. This overhang is crucial for easily lifting the finished bars out of the pan – trust me, it’s a lifesaver!
2. Make the Almond Crumb Topping: In a small bowl, combine the almond flour, granulated sugar (40g/¼ cup), toasted sliced almonds, and melted butter. Use your fingers or a fork to crumble the mixture together until it resembles coarse crumbs. Set aside; this will be sprinkled over the lemon filling later.
3. Prepare the Shortbread Crust: In a medium bowl, whisk together the all-purpose flour (120g/1 cup), powdered sugar (30g/¼ cup), and a pinch of salt. Add the cold, cubed butter. Using a pastry cutter (or your fingertips – though it’s warmer!), cut the butter into the flour mixture until it resembles coarse crumbs. This step is key for a tender, flaky crust.
4. Press & Bake the Crust: Press the crumb mixture evenly into the prepared pan. Use the bottom of a measuring cup or your fingers to firmly pack it down. Bake for 15 minutes, or until the crust is lightly golden brown. Remove from the oven and let it cool slightly while you prepare the filling.
5. Make the Raspberry Swirl: While the crust bakes, create the vibrant raspberry swirl. In a blender or food processor, combine the fresh raspberries, granulated sugar (30g/¼ cup), and lemon juice (1 tbsp). Blend until smooth. Strain the mixture through a fine-mesh sieve to remove the seeds, resulting in a silky-smooth puree. Set aside.
6. Prepare the Lemon Filling: In a large bowl, whisk together the granulated sugar (200g/1 cup), eggs, lemon juice (60ml/¼ cup), lemon zest, melted butter, and all-purpose flour (20g/2 tbsp) until the mixture is smooth and well combined. Ensure there are no lumps of flour remaining.
7. Layer and Swirl: Pour half of the lemon filling over the pre-baked crust, spreading it evenly. Drop spoonfuls of the raspberry puree over the lemon layer. Using a thin skewer or toothpick, gently swirl the raspberry puree into the lemon filling to create a beautiful marbled effect. Don’t over-swirl, or the colors will blend too much.
8. Finish & Top: Pour the remaining lemon filling over the raspberry-swirled layer, smoothing it out with a spatula. Sprinkle the prepared almond crumb topping evenly over the lemon filling, pressing it down lightly.
9. Bake to Perfection: Bake the assembled lemon bars for 20-25 minutes, or until the filling is set and the almond topping is golden brown. The center should be slightly jiggly but not liquid.
10. Cool & Chill: Remove the bars from the oven and let them cool completely in the pan on a wire rack for at least 1 hour. Then, refrigerate for at least 2 hours (or preferably overnight) to allow the filling to fully set. This is a crucial step for clean cuts.
11. Cut, Garnish & Serve: Using the parchment paper overhang, lift the slab of lemon bars onto a cutting board. Cut into squares. Dust with powdered sugar, garnish with a fresh raspberry, and optionally, a small mint leaf for a pop of color.

The Science Behind the Swirl: Why Raspberry and Lemon are a Match Made in Heaven

The combination of lemon and raspberry isn’t just delicious; it’s a flavor pairing rooted in complementary acidity and sweetness. Lemon’s bright, tart flavor is beautifully balanced by the raspberry’s slightly sweeter, more floral notes. The raspberry swirl isn’t just for aesthetics; it adds bursts of fruity flavor that cut through the richness of the lemon filling, preventing it from being overly tart. The acidity in both fruits also helps to tenderize the crust, contributing to the overall delightful texture.

Tips for a Flaky Crust

A flaky crust is the foundation of any great lemon bar. The key is to keep the butter cold! Cold butter creates pockets of steam when baking, resulting in a light and flaky texture. Don’t overwork the dough; mix just until the butter is incorporated. If the butter starts to soften too much, pop the bowl into the freezer for a few minutes. Using a pastry cutter is ideal, but your fingertips work too – just be quick!

Achieving the Perfect Lemon Filling Consistency

The lemon filling should be thick and creamy, not runny. Using the correct ratio of ingredients is essential. The flour helps to bind the filling, but too much will result in a dry, chalky texture. The eggs provide richness and structure. Be sure to whisk the filling thoroughly to ensure all ingredients are well combined and the filling is smooth.

Toasting the Almonds: A Flavor Booster

Don’t skip toasting the sliced almonds! Toasting enhances their natural nutty flavor and adds a delightful crunch to the crumb topping. You can toast them in a dry skillet over medium heat for a few minutes, or in the oven at 175°C (350°F) for 5-7 minutes, watching carefully to prevent burning.

Storing Your Lemon Bars

Lemon bars are best enjoyed within 3-4 days. Store them in an airtight container in the refrigerator to maintain their freshness and prevent the filling from becoming soggy. You can also freeze them for up to 2 months. Wrap them tightly in plastic wrap and then place them in a freezer-safe container.

Frequently Asked Questions

Can I use bottled lemon juice?

While fresh lemon juice is highly recommended for the best flavor, bottled lemon juice can be used in a pinch. However, the flavor won’t be as bright and vibrant.

Can I make these gluten-free?

Yes! Substitute the all-purpose flour in both the crust and filling with a gluten-free all-purpose flour blend.

How do I prevent the crust from getting soggy?

Baking the crust before adding the filling helps to create a barrier and prevent it from becoming soggy. Also, ensure the filling is fully set before cutting and serving.
