This Lemon Sheet Cake is ideal for a crowd! The soft, moist lemon cake is topped with a creamy and tart lemon icing that I could eat with a spoon!

  • 2 cups all purpose flour
  • 2 cups granulated sugar
  • 1 teaspoon baking soda
  • 1/2 teaspoon kosher salt
  • 2 tablespoons lemon zest
  • 1 cup butter 
  • 1/2 cup water
  • 1/2 cup fresh squeezed lemon juice
