Method
 

Step-by-Step Instructions for Sheet Cake
  1. Preheat your oven to 350°F (175°C) and prepare a 9x13 inch baking pan by greasing and flouring it.
  2. In a large bowl, whisk together the dry ingredients: flour, sugar, cocoa powder, baking powder, baking soda, and salt.
  3. In a separate bowl, mix the wet ingredients: buttermilk, vegetable oil, eggs, and vanilla extract until smooth.
  4. Gradually add the wet mixture to the dry ingredients, mixing on low speed until just combined.
  5. Carefully mix in the boiling water until the batter is smooth.
  6. Pour the batter into the prepared pan and bake for 30-35 minutes.
  7. Let the cake cool in the pan for 10-15 minutes before inverting onto a wire rack to cool completely.
  8. For the ganache, heat heavy cream until it simmers, then add chopped chocolate and stir until smooth.
  9. Stir in unsalted butter, vanilla extract, and salt until well combined.
  10. Cool the ganache to a spreadable consistency.
  11. For the cream cheese frosting, beat cream cheese until smooth, then gradually add powdered sugar.
  12. Mix in milk and vanilla extract until desired consistency is reached.
  13. Spread the ganache evenly over the cooled cake.
  14. Pipe cream cheese frosting over ganache in decorative lines.
  15. Create swirls with a toothpick through the piped frosting.
  16. Refrigerate for at least 30 minutes to let frosting set before serving.
