Description
A recipe for tangy dessert bars featuring a shortbread crust, a creamy sour cream filling, and bright lemon flavor mixed with fresh rhubarb.
Ingredients
Scale
- 1 1/2 cups all-purpose flour
- 1/2 cup granulated sugar
- 1/2 cup cold unsalted butter, cubed
- 1/4 teaspoon salt
- 1 cup granulated sugar (for filling)
- 1/4 cup all-purpose flour (for filling)
- 1 tablespoon lemon zest
- 2 tablespoons fresh lemon juice
- 1 cup sour cream
- 2 large eggs
- 2 cups chopped fresh rhubarb (about 1/2 inch pieces)
Instructions
- Preheat your oven to 350 degrees Fahrenheit. Line a 9×9 inch baking pan with parchment paper, leaving an overhang for easy removal.
- Prepare the crust: In a medium bowl, combine 1 1/2 cups flour, 1/2 cup sugar, and salt. Cut in the cold butter using a pastry blender or your fingers until the mixture resembles coarse crumbs.
- Press the crumb mixture evenly into the bottom of the prepared pan to form the crust. Bake the crust for 12 minutes until lightly set.
- While the crust bakes, prepare the filling: In a large bowl, whisk together 1 cup sugar, 1/4 cup flour, lemon zest, and lemon juice.
- Add the sour cream and eggs to the sugar mixture. Whisk until smooth and well combined.
- Gently fold in the chopped rhubarb pieces.
- Pour the sour cream and rhubarb filling evenly over the warm, pre-baked crust.
- Return the pan to the oven and bake for 40 to 45 minutes, or until the center is mostly set and a toothpick inserted near the edge comes out clean. The center might still jiggle slightly.
- Let the squares cool completely in the pan on a wire rack, about 2 hours, before lifting them out using the parchment paper overhang.
- Cut into 16 squares before serving.
Notes
- For a firmer crust, chill the dough for 15 minutes before pressing it into the pan.
- Do not overbake; the squares will firm up as they cool.
- If your rhubarb is very tart, you may increase the filling sugar by 1/4 cup.
