Method
 

Step-by-Step Instructions
  1. Preheat your oven to 350°F (175°C) and prepare a 10x15-inch sheet pan by greasing it or lining it with parchment paper.
  2. In a large mixing bowl, whisk together flour, sugar, salt, and baking soda until combined.
  3. In a medium saucepan, combine butter, water, and cocoa powder over medium heat, whisking until smooth.
  4. Pour the chocolate mixture into the dry ingredients, then add buttermilk, eggs, and vanilla. Stir until smooth.
  5. Pour the batter into the prepared sheet pan and bake for 18-22 minutes, checking for doneness with a toothpick.
  6. In another saucepan, melt butter and peanut butter over low heat, then whisk in milk, powdered sugar, vanilla, and salt until smooth.
  7. Once the cake is done, pour the warm frosting over it immediately, spreading gently and letting cool for at least 30 minutes.
