Recipe Information
Ingredients
- 1.5 cups all-purpose flour
- 0.5 cups unsalted butter
- 0.25 cups powdered sugar
- 1 cups granulated sugar
- 3 pieces large eggs
- 0.5 cups lemon juice
- 1 tablespoon lemon zest
- 0.5 cups sour cream
- 2 tablespoons cornstarch
- 0.25 teaspoons baking powder
- 2 tablespoons powdered sugar (for garnish)
Instructions
Preheat your oven to 350°F (175°C) and line an 8x8-inch baking pan with parchment paper, leaving an overhang for easy removal.
In a medium bowl, combine the all-purpose flour and powdered sugar for the crust.
Cut the unsalted butter into small cubes and add it to the flour mixture. Use a fork or pastry cutter to blend until the mixture forms a crumbly dough.
Press the dough evenly into the bottom of the prepared baking pan. Bake the crust for 15 minutes until lightly golden. Remove from the oven and let cool slightly.
In a large bowl, whisk together the granulated sugar, eggs, and sour cream until smooth and well combined.
Add the lemon juice, lemon zest, cornstarch, and baking powder to the egg mixture. Mix until fully incorporated.
Pour the lemon filling over the pre-baked crust, spreading it evenly.
Return the pan to the oven and bake for 20 minutes, or until the filling is set and no longer jiggly in the center.
Allow the lemon slice to cool completely in the pan, then refrigerate for at least 2 hours to firm up.
Using the parchment overhang, carefully lift the slice out of the pan and onto a cutting board.
Dust the top with powdered sugar, then cut into 12 bars or squares before serving.
