Preparation

• Heat oven to 350F and line a 9x13 baking dish with parchment paper.
• Whisk together 2 ½ cups of flour (300g) with the powdered sugar and salt, then pour in the melted butter and mix until combined.
• Sprinkle the dough into your lined pan and press down into a flat layer. Bake at 350F for about 20 minutes or until a light golden color.
• While the crust is baking add the sugar to a food processor and add the zest of three lemons. Pulse until the zest is fully incorporated and sugar is a light yellow color.
• Add the sugar and remaining half cup of flour to a large bowl and mix well.
• Pour in the lemon juice and add the eggs then mix very well until completely combined.
• Pour the filling onto the warm crust then transfer to oven and bake for about 25 minutes, turning halfway through the bake.
• Remove from oven and allow to cool for an hour before chilling in the refrigerator for two hours.
• Dust with powdered sugar and cut into bars using a clean, sharp, damp knife.
