Ingredients

Base

  • 1/2 cup (4oz) cold butter cut into 1-inch chunks
  • 1 cup (140g) all-purpose flour
  • 1/4 cup (30g) powdered sugar + optional extra for dusting

Filling

  • 1 cup (200g) granulated sugar
  • 2 large eggs
  • 1/4 cup freshly-squeezed lemon juice 1-2 medium lemons
  • 1 1/2 teaspoon lemon zest about 1/2 lemon

Instructions

  1. Preheat your oven to 350°F. Spray an 8x8 baking pan very well with cooking spray.

  2. In a food processor, mix butter, flour, and powdered sugar until your dough begins to come together. There is probably going to be a minute where it looks like the ingredients aren't going to form a dough, but just keep mixing. It will. When the dough begins to clump and can be pressed together, dump it out into your greased pan and press into an even layer, all the way to the edges.

  3. Bake for 15-20 minutes, until the crust is lightly golden.

Custard

  1. Make the custard while your base is baking. Whisk sugar, eggs, lemon juice, and lemon zest together until well combined. Once your crust is lightly golden, open oven and carefully pour lemon mixture into the pan, without removing it from the oven.
  2. Bake for 20-25 minutes more, until the filling is completely set.
  3. Allow to cool completely before dusting lightly with powdered sugar (if desired) and cutting.

Recipe Notes

To make designs on the tops of your bars, you can cut shapes from parchment paper and lay over the top of your custard before dusting with powdered sugar. Because these are so moist, they will absorb some of the sugar (mine started to look a little sparse after about an hour) so if serving to guests, dust shortly before serving or apply a heavier layer of sugar at the start.
