  • 2 cups Flour
  • 1 cup Butter melted
  • 1/2 cup Sugar

Lemon Filling

  • 4 large Eggs
  • 4 tablespoons Lemon Juice
  • 2 cups Sugar
  • 4 tablespoons Flour
  • 1 teaspoon Baking Powder
  • 1/4 cup Powdered Sugar

Crumble Topping

  • cups Flour
  • 3/4 cup Brown Sugar
  • 1/4 teaspoon Salt
  • 3/4 cup Butter


  • Preheat the oven to 350 degrees. Grease a 13 x 9 baking dish or pan.
  • Mix the 2 cups flour, butter, and 1/2 sugar and press firmly into the bottom of the prepared dish or pan. Place in the oven and bake for 15 minutes. Remove and set aside.
  • In a medium bowl whisk the eggs slightly and add in the lemon juice, 2 cups sugar, 4 tablespoons flour, and baking powder. Whisk the ingredients to fully combine and pour over the crust.
  • In a medium bowl, mix the 1 1/2 cups flour, 3/4 cup brown sugar, and 1/3 cup sugar. Cut 1 1/2 sticks chilled unsalted butter into pieces. Use your hand to work in the butter pieces, until large clumps begin to form. Sprinkle on top of the lemon mixture.
  • Bake for 25 minutes or until the center of the bars is slightly firm to touch. Once cooled completely sprinkle the top with powdered sugar.


If you’re making this for a smaller crowd then split the entire list of ingredients in half.
To make the “original” version of this recipe then remove the crumble and just sprinkle the tops of the bars with powdered sugar.
