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 the Cranberries: Rinse the cranberries carefully, picking out any that are damaged or squishy. In a medium saucepan, combine cranberries, water, and 6 tablespoons of granulated sugar. Bring to a boil over medium-high heat, then reduce to medium-low and cover with a splatter screen. Stir occasionally at first and then more frequently to avoid burning. Simmer for 10-15 minutes until the cranberries have broken down completely. Set aside to cool for at least 30 minutes.
- Preheat and Prepare Pan: Preheat oven to 325°F (163°C). Line a 9-inch square baking dish with parchment paper, ensuring no gaps and leaving an overhang to easily lift bars later. Grease the parchment paper well with butter or non-stick cooking spray and set aside.
- Make Shortbread Crust: In a medium bowl, mix melted butter, vanilla extract, 1/4 cup granulated sugar, and salt until combined. Add 1 cup plus 1 tablespoon of all-purpose flour and mix to form a thick dough. Press the dough evenly and firmly into the prepared baking pan.
- Bake Crust: Bake the crust for 16-18 minutes until lightly browned. Remove from the oven and poke holes evenly across the crust with a fork. Turn off the oven and allow the crust to cool about 20 minutes.
- Prepare Lemon Layer Mixture: While crust cools, whisk together 3 tablespoons flour and 1 cup granulated sugar in a medium bowl. Whisk in the eggs thoroughly and then stir in fresh lemon juice. Set aside.
- Assemble Cranberry Layer: Spread the cooled cranberry filling evenly over the cooled crust, covering edges without gaps. Refrigerate for 45 minutes to set.
- Bake Lemon Layer: Increase oven temperature to 350°F (177°C). Remove the pan from the refrigerator and carefully pour the lemon mixture over the cranberry layer. Bake for 43-45 minutes until the center is set and does not jiggle.
- Cool and Serve: Cool the bars on a wire rack in the baking pan at room temperature for 1 hour, then refrigerate for 1-2 hours. To serve, lift bars out of pan using parchment overhang, sprinkle with powdered sugar if desired, and cut into 16 squares. Wipe knife between cuts for clean slices.
Notes
- Use fresh or frozen cranberries; if frozen, do not thaw before cooking.
- Ensure the crust is fully cooled before adding cranberry layer to prevent layering problems.
- Chilling the cranberry layer before adding lemon custard helps maintain distinct layers.
- For the freshest lemon juice, use lemons at room temperature and strain seeds beforehand.
- Allow the bars to chill thoroughly before cutting to achieve clean, firm slices.
- Powdered sugar topping is optional but adds a nice sweet contrast to tart layers.
