Lemon Raspberry Swirl Bars (Printable)
Tangy lemon filling meets sweet raspberry swirl on a buttery shortbread crust. An elegant dessert perfect for any occasion.
# What You Need:
→ Shortbread Crust
01 - 1 cup all-purpose flour
02 - 1/4 cup powdered sugar
03 - 1/4 tsp salt
04 - 1/2 cup unsalted butter, cold and cubed
→ Lemon Filling
05 - 1 cup granulated sugar
06 - 2 large eggs
07 - 1/4 cup all-purpose flour
08 - 1/2 cup freshly squeezed lemon juice
09 - 1 tbsp lemon zest
10 - 1/4 tsp salt
→ Raspberry Swirl
11 - 1/2 cup fresh raspberries
12 - 2 tbsp granulated sugar
13 - 1 tsp lemon juice
→ For Dusting (Optional)
14 - Powdered sugar
# Directions:
01 - Preheat oven to 350°F. Line an 8x8-inch baking pan with parchment paper, allowing overhang for easy removal later.
02 - In a medium bowl, combine flour, powdered sugar, and salt. Cut in cold butter using a pastry cutter or fork until mixture resembles coarse crumbs. Press mixture evenly into the prepared pan.
03 - Bake crust for 18 to 20 minutes until lightly golden. Remove from oven while keeping the oven temperature maintained.
04 - While crust bakes, combine raspberries, 2 tablespoons sugar, and 1 teaspoon lemon juice in a small saucepan. Cook over medium heat for 3 to 4 minutes, stirring occasionally until raspberries break down and mixture thickens. Strain through a fine mesh sieve to remove seeds. Set aside.
05 - In a separate bowl, whisk granulated sugar and eggs until smooth. Add flour, lemon juice, lemon zest, and salt. Whisk until fully incorporated.
06 - Pour lemon filling over the warm crust. Drop teaspoons of raspberry sauce over the lemon layer. Use a toothpick or knife to gently swirl the raspberry sauce into the lemon filling, creating a marbled pattern.
07 - Bake for 20 to 22 minutes until the center is just set and no longer jiggles when gently shaken.
08 - Cool completely in the pan on a wire rack. Refrigerate for at least 2 hours before slicing into bars.
09 - Dust with powdered sugar before serving, if desired. For clean slices, wipe the knife between cuts.
# Expert Tips:
01 -
- The sweet-tart dance between bright lemon and sun-ripened raspberries creates layers of flavor that keep everyone guessing
- That buttery shortbread crust practically melts on your tongue while adding just enough structure to hold everything together
02 -
- A warm crust prevents the filling from seeping underneath, so pour that lemon mixture right after the crust comes out of the oven
- Overbaking creates a rubbery texture, so pull them when the center barely jiggles instead of waiting for complete stillness
03 -
- Room temperature eggs whisk into the filling more smoothly, preventing those pesky little white specks
- The parchment paper overhang is absolutely essential for lifting the whole batch out without breaking corners
