Ingredients

Units Scale

Graham Cracker Crust

  • 9 regular sized graham crackers, ground fine (about 1 1/2 cups)
  • 2 tbsp brown sugar, packed
  • 56 tbsp salted butter, melted

Lemon square filling

  • 4 eggs, beaten
  • 1/2 cup lemon juice
  • zest of 1 lemon
  • 1 1/4 cup granulated sugar
  • 1/4 tsp salt
  • 1/3 cup all-purpose flour
  • Powdered sugar, for dusting

Instructions

  1. Preheat oven to 350F.
  2. Pulse graham crackers in a blender until finely ground.
  3. In a small mixing bowl, combine ground graham crackers, melted butter and brown sugar. Mix well until graham cracker crumbs are fully moistened. If it seems too dry, add another up to 1 tbsp more of melted butter. 
  4. Line an 8 x 8 baking dish with parchment and press the crust mixture into the bottom of the pan firmly and evenly. Use the bottom of a drinking glass to ensure the crust is firmly packed and even.
  5. Bake for 12 minutes on a lower rack of the oven. Once you remove the crust from the oven, use the bottom of a glass to gentle press down the crust once more.
  6. Mix the filling once you remove the crust from the oven. Combine lemon zest, juice, sugar, salt and flour. Then add the beaten eggs. Whisk to combine.
  7. Pour lemon filling mixture over crust (do this slowly and gently) and bake for about 17-22 minutes (again on the lower rack), until mostly set. A tiny jiggle in the center is the sweet spot.
  8. Allow lemon squares to cool for 1 hour in the pan, then transfer to the fridge for at least one more hour to chill and set. 
  9. Dust with powdered sugar just before slicing and serving. Serve chilled.
