What Ingredients You Will Need
This recipe uses simple, wholesome ingredients to create bold flavors and stunning visuals. Most of these are probably already in your kitchen!
For the Shortbread Crust:
- 1 cup (125g) all-purpose flour
- 1/4 cup (50g) granulated sugar
- 1/2 cup (115g) unsalted butter, softened
- Pinch of salt
For the Lemon Filling:
- 3 large eggs, room temperature
- 1 cup (200g) granulated sugar
- 1/3 cup (80ml) fresh lemon juice (about 2-3 lemons)
- 2 tablespoons (30g) all-purpose flour
- 1 tablespoon lemon zest
For the Raspberry Swirl:
- 1/2 cup (75g) fresh raspberries
- 2 tablespoons (25g) granulated sugar
If raspberries aren’t in season, frozen ones work just as well! Make sure to thaw and drain them before blending.
Equipment Needed
- 9×9-inch baking pan: A square pan works best for even baking.
- Mixing bowls: You’ll need separate bowls for the crust, filling, and raspberry puree.
- Food processor or blender: For creating the smooth raspberry puree.
- Whisk: Essential for a silky lemon filling.
- Spatula: Helps spread the filling evenly and create the swirl effect.
If you don’t have a food processor, a fork and some elbow grease will work to mash the raspberries. Also, parchment paper is your friend for easy removal and clean-up!
Preparation Method
- Preheat the Oven: Preheat your oven to 350°F (175°C). Line your baking pan with parchment paper, leaving some overhang for easy removal later.
- Make the Shortbread Crust: In a mixing bowl, combine the flour, sugar, butter, and salt. Mix until the dough comes together and resembles coarse crumbs. Press it evenly into the prepared pan. Bake for 15 minutes or until lightly golden. Set aside.
- Prepare the Lemon Filling: In another bowl, whisk together the eggs, sugar, lemon juice, flour, and zest until smooth. Pour the filling over the cooled shortbread crust.
- Make the Raspberry Swirl: Blend the raspberries and sugar in a food processor until smooth. Strain the puree through a fine mesh sieve to remove seeds.
- Create the Swirl: Drop small spoonfuls of raspberry puree onto the lemon filling. Use a toothpick or skewer to gently swirl the raspberry puree into the lemon layer, creating a marbled effect.
- Bake: Bake the bars for 25-30 minutes, or until the filling is set and no longer jiggles in the center. Let cool completely before slicing.
- Slice and Serve: Once cooled, lift the bars out using the parchment overhang. Slice into squares and enjoy!
Cooking Tips & Techniques
- Don’t Overmix: When preparing the shortbread crust, mix just until the dough comes together to avoid a tough texture.
- Room-Temperature Ingredients: Using room-temperature eggs ensures a smooth lemon filling without curdling.
- Cool Completely: Allow the bars to cool thoroughly before slicing to avoid a runny filling.
- Swirl Gently: Use light strokes when swirling the raspberry puree to create a clean, marbled effect.
- Test for Doneness: The center of the bars should be set but still slightly soft when you remove them from the oven.
Variations & Adaptations
- Gluten-Free Option: Substitute the all-purpose flour with a gluten-free flour blend for both the crust and filling.
- Dairy-Free Swap: Use vegan butter for the crust to make this recipe dairy-free.
- Berry Variations: Swap raspberries for blackberries, strawberries, or blueberries for a different flavor twist.
- Low-Sugar Version: Reduce the sugar in the filling and puree slightly for a less sweet treat.
- Mini Bars: Bake in a mini muffin tin for bite-sized portions—perfect for parties!
