Ingredients

FOR THE CAKE

  • 2 sticks salted butter
  • 1/2 cup freshly squeezed lemon juice
  • 2 tablespoons lemon zest
  • 1 cup water
  • 8 ounces sour cream
  • 2 whole eggs
  • 1 teaspoon pure vanilla extract
  • 2 1/2 cups all-purpose flour
  • 2 1/2 cups sugar
  • 1 1/4 teaspoons baking soda
  • 1/2 teaspoon kosher salt

FOR THE GLAZE

  • 1/3 cup freshly squeezed lemon juice
  • 1 tablespoons lemon zest
  • 3 1/2 cups powdered sugar do not pack

Instructions

FOR THE CAKE

  • Grease a 16.5 x 11.38 sheet pan and set aside.
  • Preheat oven to 350 degrees and adjust the rack to the middle position.
  • In a large pot, melt the butter over medium heat.
  • Add the water and the lemon juice, increase the heat to high, and bring to a boil. Immediately remove the pot from the heat and allow to cool for at least 5 to 10 minutes. 
  • Whisk in the flour until smooth, followed by the sugar, sour cream, and lemon zest. Do not over beat, just mix until combined.
  • Whisk in eggs one at a time until well blended.
  • Mix in the vanilla extract, and then sprinkle the baking soda and salt over the top of the batter and whisk until all ingredients are well blended.
  • Pour the batter into the prepared sheet pan and smooth the top. Bake for 15 to 20 minutes or until a toothpick inserted into the center of the cake comes out clean. Allow cake to cool before glazing.

FOR THE GLAZE

  • In a large bowl, whisk together the powdered sugar, lemon juice, and lemon zest until completely smooth. 
  • Adjust consistency by adding more lemon juice if the glaze is too thick or more powdered sugar if it's too thin. 
  • Immediately pour the prepared glaze over the cooled cake and spread evenly.
  • If desired, garnish with lemon slices.
  • Chill (uncovered) for at least 30 minutes to allow the glaze to set before slicing. Cover tightly and refrigerate any leftovers.
