Instructions
Preheat oven to 350 degrees F. Line an 8-inch square metal pan with foil and spray foil with cooking spray or line with parchment paper.
Cream butter, sugar and salt together in a mixing bowl. Add flour and stir just until mixed. Press dough into bottom of pan. Dock the dough with a fork and bake for 15-18 minutes.
Whisk yolks, condensed milk, lemon juice and zest until well combined. Remove the baking pan from the oven and pour the filling over the hot crust - place back into the oven and bake until filling is set, about 22 to 28 minutes. Remove and cool completely.
Place the pan into the refrigerator and chill until firm, about 2 hours. Grasp foil, lift from pan, slice bars into quarters, then slice each quarter into a triangle to make 8 triangles. Serve with whipped cream and fresh seasonal berries.
