Method:
- Preheat your oven to 350°F (175°C). Grease and flour a 9x13 inch baking pan.
- In a large mixing bowl, combine the unsalted butter and Dutch-process cocoa powder. Pour in the hot water, whisking until well combined. Let this mixture cool slightly.
- In another bowl, whisk together the all-purpose flour, espresso powder, baking soda, and salt. Set aside.
- Once the cocoa mixture has cooled, add the granulated sugar, buttermilk, eggs, and vanilla extract. Mix until smooth.
- Gradually add the dry ingredients to the wet ingredients, stirring gently until just combined.
- Pour the batter into the prepared baking pan. Bake for 30-35 minutes or until a toothpick comes out clean. Allow to cool in the pan for 10 minutes before transferring to a cooling rack.
- In a double boiler or microwave, melt the semisweet chocolate chips with 1 cup of heavy cream and 1 teaspoon of vanilla extract until smooth. Stir in the light corn syrup.
- In a mixing bowl, beat together the unsalted butter and vegetable shortening until creamy. Gradually add sifted powdered sugar until light and fluffy. Mix in cocoa powder, 1/4 cup of heavy cream, and 0.5 teaspoon of vanilla extract until smooth.
- Once the cake has cooled, cut it into squares. Spread a layer of chocolate ganache on half of the squares, then top with another square. Frost the tops with chocolate frosting.
- Sprinkle with extra chocolate chips or dust with powdered sugar before serving.
