Instructions

  1. Step 1: Preheat oven to 350°F. In a large bowl, sift together 2 cups all-purpose flour, 2 cups granulated sugar, 3/4 cup unsweetened cocoa powder, 1 1/2 tsp baking soda, 1 1/2 tsp baking powder, and 1 tsp salt.
  2. Step 2: In another bowl, whisk 2 large eggs, 1 cup buttermilk, 1 cup cooled strong brewed espresso, 1/2 cup vegetable oil, and 2 tsp vanilla extract. Gradually add wet ingredients to dry ingredients, mixing until smooth.
  3. Step 3: Carefully stir in 1 cup boiling water until batter is thin and well combined. Pour batter into a greased 9x13-inch sheet pan.
  4. Step 4: Bake for 35-40 minutes, testing doneness with a toothpick inserted in the center. Cool completely on a wire rack.
  5. Step 5: For ganache, heat 1 cup heavy cream in a small saucepan over medium heat until it just begins to simmer. Pour over 8 oz semi-sweet chocolate chips in a heatproof bowl and let sit 5 minutes, then whisk until smooth.
  6. Step 6: Refrigerate ganache for 1 hour until thickened but still spreadable. Whip ganache with a mixer for 2-3 minutes until fluffy.
  7. Step 7: Spread whipped ganache evenly over cooled cake and serve.
