Ingredients

For the chocolate cake:

  • 1 cup butter unsalted
  • 1 cup water
  • ⅓ cup unsweetened cocoa
  • 2 cups all-purpose flour
  • 2 cups sugar
  • ¾ teaspoon salt
  • 1 teaspoon baking soda
  • 2 large eggs

For the chocolate icing:

  • 6 tablespoons whole milk
  • ½ cup butter unsalted
  • 3 tablespoons unsweetened cocoa powder
  • pinch salt
  • 3¾ cups powdered sugar

Instructions

  • Preheat oven to 350 degrees. Prepare a half baking sheet (18x13) by lining with parchment paper. Spray parchment paper with nonstick spray. Set aside.
  • Place 1 cup of water, 1 cup of butter, and ⅓ cup of cocoa powder into a medium saucepan. Set over medium heat until boil. Whisk together to remove lumps. Turn off heat and set aside to cool slightly.
  • Add 2 cups of sugar, 2 cups of flour, baking soda, and ¾ teaspoon of salt to a large bowl. Whisk together. In a separate small bowl, whisk sour cream, eggs and vanilla together until smooth. Add to the dry ingredients and fold together loosely. Add chocolate mixture about ⅓ at a time, whisking together into the dry/wet ingredients mixture until smooth.
  • Pour chocolate cake batter into prepared sheet pan . Smooth out into an even layer. Place into preheated oven and bake until cooked through, about 15 minutes.
  • Remove from oven and let cool for 5 mins and then cover with chocolate icing (recipe below). Smooth icing into an even layer. Cool for 10 more minutes before serving.

For the chocolate icing:

  • Add butter, milk, and cocoa powder to same medium sauce pan used previously. Set over medium heat until boiling. Once boiling, remove from heat and whisk together to remove lumps. When smooth, add powdered sugar and whisk together vigorously until smooth. This may take about 1 minute.
