Ingredients
Cranberry Layer
- 8 ounces fresh cranberries or frozen (not thawed)
- 1/2 cup water
- 6 tablespoons granulated sugar
Shortbread Crust
- 1/2 cup (1 stick) unsalted butter, melted
- 1/4 cup granulated sugar
- 1 teaspoon vanilla extract
- 1/4 teaspoon salt
- 1 cup + 1 tablespoon all-purpose flour
Lemon Layer
- 1 cup granulated sugar
- 3 tablespoons all-purpose flour
- 3 large eggs
- 1/2 cup fresh lemon juice (about 3 lemons)
- Optional: powdered sugar for sprinkling on top
Instructions
- Prepare Cranberries: Rinse and carefully pick through the cranberries, discarding any that are bad or squishy. In a medium saucepan, combine cranberries, water, and 6 tablespoons sugar. Bring the mixture to a boil over medium-high heat, then reduce to medium-low, cover with a splatter screen, and simmer while stirring initially, then constantly to avoid burning until the berries break down (about 10-15 minutes). Set aside to cool for at least 30 minutes.
- Preheat and Prepare Pan: Preheat oven to 325°F. Line a 9-inch square baking dish with parchment paper, making sure to cover all sides with some overhang for easy removal. Butter or spray the parchment paper to prevent sticking.
- Make Shortbread Crust: In a medium bowl, mix the melted butter, vanilla extract, 1/4 cup sugar, and salt until combined. Stir in 1 cup plus 1 tablespoon of flour until a thick dough forms. Press this dough evenly into the prepared pan, ensuring it reaches all edges to prevent filling leakage.
- Bake Crust: Bake the crust for 16-18 minutes until lightly browned. Remove from oven and pierce the crust all over with a fork. Turn off the oven and allow the crust to cool about 20 minutes.
- Prepare Lemon Layer: While the crust cools, whisk together 3 tablespoons flour and 1 cup sugar in a bowl. Add eggs and then lemon juice, whisking until smooth and combined. Set aside.
- Assemble Cranberry Layer: Pour the cooled cranberry mixture evenly over the cooled crust, spreading to the edges with no gaps. Refrigerate for 45 minutes to set the cranberry layer.
- Bake Lemon Layer: Preheat oven to 350°F. Remove the pan from the refrigerator and carefully pour the lemon mixture on top of the cranberry layer. Bake for 43-45 minutes, or until the lemon custard is set and does not jiggle.
- Cool and Serve: Cool the bars on a wire rack in the pan at room temperature for 1 hour, then chill in the refrigerator for 1-2 hours. To serve, lift the bars out using the parchment overhang and place on a cutting board. Dust with powdered sugar if desired and cut into 16 squares, wiping the knife between cuts for clean slices.
Notes
- This recipe is time-intensive and requires patience due to multiple cooling and baking steps.
- Ensure the crust reaches the edges fully to prevent filling leakage.
- Use a splatter screen to safely simmer the cranberry mixture without mess.
- For best results, chill the cranberry layer before adding the lemon custard.
- Wiping the knife between cuts results in clean slices.
- If fresh cranberries are unavailable, frozen can be used without thawing.
- Optionally sprinkle powdered sugar on top for an attractive finish.
