- 1/2 cup (1 stick) unsalted butter, room temperature, plus more for pan
- 1/2 cup confectioners’ sugar, plus more for dusting
- 1/4 teaspoon salt
- 1 cup all-purpose flour (spooned and leveled)
- 4 large egg yolks
- 1 can (14 ounces) sweetened condensed milk
- 3/4 cup fresh lemon juice (from about 3 lemons)
- Preheat oven to 350 degrees. Butter an 8-inch square baking pan. Line bottom with parchment paper, leaving an overhang on two sides; butter paper.
- Make crust: Using an electric mixer, beat butter, sugar, and salt until light and fluffy. Add flour, and mix on low just until combined. Press dough into the bottom and 1/2 inch up sides of prepared pan; prick all over with a fork. Bake until lightly golden, 15 to 20 minutes.
- Make filling: In a large bowl, whisk together yolks, condensed milk, and lemon juice until smooth. Pour over hot crust in pan; return to oven, and bake until filling is set, 25 to 30 minutes. Cool completely in pan.
- Refrigerate until filling is firm, about 2 hours or up to 3 days. Using paper overhang, lift cake onto a work surface; cut into 16 squares, and dust with confectioners sugar.
I cut this recipe in half, because I will most likely be the only person eating them, and I really don’t need 16! It was easy enough to follow. I made the crust, and I didn’t have any parchment paper. This didn’t really cause any problems, but it would have been helpful. The crust took a lot longer to bake than the recipe said, about 35 minutes.
When that was done, I pour the filling in and put it back in the oven for about 20 minutes. I let it cool on the stove, then put it in the fridge for 2 hours. They turned out delicious! They didn’t look very pretty, but they tasted great!
