Ingredients

Crust Ingredients

  • cups All-purpose flour
  • cup Confectioners sugar
  • ¾ cup Butter softened (1-½ sticks)
  • ¼ teaspoon Vanilla extract
  • ¼ teaspoon Baking soda
  • ¼ teaspoon Lemon zest

Lemon Custard Filling

  • 6 Eggs
  • 2 cups Granulated sugar
  • 6 Tablespoons All-purpose flour
  • ½ cup Freshly squeezed lemon juice about 1-½ lemons
  • ½ teaspoon Lemon zest

Instructions

Lemon Bar Crust

  • Preheat the oven to 350℉. Grease a 9X13 baking pan with butter and set aside.
  • Add the crust ingredients into the bowl and mix with a hand mixer on low speed for 2 minutes until the consistency is crumbly.
  • Bake the crust for 22 minutes until the edges are golden brown.
  • Remove the pan from the oven and place on a cooling rack. (The crust does NOT need to cool beyond the time it takes to prepare the lemon custard.)

Lemon Custard Filling

  • In a bowl add the lemon custard ingredients.
  • Use a hand mixer on low for 2 minutes until the consistency is smooth and silky.
  • Pour the lemon custard over the crust.
  • Bake for 25 minutes. Use a toothpick to make sure the lemon custard comes out clean.
  • Place the baking dish on a cooling rack for 1 hour until cooled. Transfer the pan to the fridge for 2 hours or until chilled.
  • Cut into 20 bars.
  • Sprinkle with powdered sugar, if desired. Add an additional lemon slice (optional)

Notes

  • Use a glass or ceramic pan. Do not use metal, the lemon bars will taste metallic. 
  • Always use fresh juice over store-bought. The taste will be more flavorful with fresh juice. 
  • The bars may seem wobbly and not fully set, even though the toothpick comes out clean, but they will continue to bake while cooling and set.
  • The chill time is extremely important for the bars to be completely set.
  • These can be gluten-free by replacing the all-purpose flour with gluten-free all purpose flour.
