Preparation : 15 min Cooking : 45 min Standing : 3 h Cooking Dish : 22x32 cm pan
400 calories/serving


parchment paper
1 cup butter, unsalted, melted 240 g
2 cups sugar 400 g
2 tsp vanilla extract 10 mL
1/2 tsp salt 2 g
2 1/4 cups white flour (all purpose) 300 g
6 eggs size large
2 lemons 240 g
1 grapefruits 300 g
1 tbsp icing/confectioners' sugar [optional] 8 g


  1. Preheat the oven to 165°C/325°F. Line the bottom and sides of a 22×32 cm (9x13 in) ceramic baking pan with parchment paper, leaving an overhang on the sides to lift the finished bars out (makes cutting easier!).
  2. Mix the melted butter, 100 g sugar, vanilla extract, and salt together in a medium bowl. Add 250 g flour and stir to completely combine. The dough will be thick. Press firmly into prepared pan, making sure the layer of crust is nice and even.
  3. Bake in the middle of the oven for 20-22 min. or until the edges are lightly browned. Remove from the oven. Using a fork, poke holes all over the top of the warm crust (this will helps the filling stick and holds the crust in place). Set aside.
  4. Meanwhile prepare the filling: Sift the remaining sugar and flour together in a large bowl. Whisk in the eggs. Press the lemons and grapefruit then add the juice (about 250 mL) to the bowl. Mix until completely combined. Pour filling over warm crust.
  5. Put the baking pan back in the middle of the oven and bake for 22-26 min or until the center is relatively set and no longer jiggles. Remove from the oven and cool completely at room temperature (about 2 hours). Chill in the refrigerator for 1-2 more hours until chilled.
  6. Once cool, lift the parchment paper out of the pan using the overhang on the sides. Dust with confectioners' sugar and cut into 24 squares before serving. For neat squares, wipe the knife clean between each cut.


Calculate 2 bars per person. Leftover bars can be stored in the refrigerator for up to one week.
