- 1 ¼ cups sugar
- 1 cup + 3 tablespoons flour
- 1/4 teaspoon salt
- ½ cup unsalted butter, room temperature
- 3 eggs, room temperature
- ½ cup lemon juice
- ½ tablespoon lemon zest
- 1 teaspoon powdered sugar
- Preheat the oven to 350 F. Grease and line a small baking dish (approximately 9x6.5-inch) or eighth sheet pan with parchment paper. Make sure the parchment paper fully covers the sides of the dish, so that the finished lemon bars can be easily removed.
- In a stand mixer, sift ¼ cup of sugar with 1 cup of plain flour and ¼ of salt, and then combine with ½ cup of butter until the mixture is crumbly.
- Press the mixture into the base of the prepared baking dish and make it as even as possible. Using a fork, prick the base several times and then bake this for 25 minutes.
- Meanwhile, in a stand mixer, sift together the remaining 1 cup of sugar with 3 tablespoons of plain flour. Then, mix in the 3 eggs, ½ cup of lemon juice, and ½ tablespoon of lemon zest.
- When the base is ready, remove it from the oven and drop the oven temperature slightly, to 325 F.
- Leave the base to cool for 5 minutes or so, before pouring the lemon layer over the top. Put this straight back in the oven and bake for another 25 minutes, until the lemon layer has set.
- Take the baked lemon bars out of the oven and leave them to cool completely, before transferring them to the fridge to set further, either for 4 hours or overnight.
- To serve, slice the lemon bar block into 6 even squares, dust with powdered sugar, and decorate with dried lemon slices.
