Step 1: Preheat Oven:
Begin by preheating your oven to 350°F (175°C) and prepare three 9-inch round cake pans by greasing and flouring them. This ensures the cakes won’t stick and allows for easy removal.
Step 2: Prepare Wet Ingredients:
In a large mixing bowl, combine hot water (or brewed coffee), buttermilk, sour cream (or Greek yogurt), eggs, vegetable oil, and vanilla extract. Thoroughly mix these wet ingredients to form a smooth and cohesive base.
Step 3: Melt Dark Chocolate:
In a separate bowl, melt dark chocolate using a double boiler or microwave. Introduce the melted chocolate into the wet ingredients, stirring until the mixture achieves a velvety consistency.
Step 4: Combine Dry Ingredients:
In another bowl, sift together all-purpose flour, sugar, Dutch-processed cocoa, baking soda, baking powder, and sea salt. This ensures an even distribution of dry ingredients and prevents lumps.
Step 5: Mix Batter:
Gradually add the sifted dry ingredients to the wet ingredients, mixing until just combined. Be cautious not to overmix, as it can affect the texture of the cake.
Step 6: Bake:
Divide the batter evenly among the prepared cake pans. Bake in the preheated oven for 30-35 minutes or until a toothpick inserted into the center comes out clean, indicating that the cakes are fully baked.
Step 7: Prepare Frosting:
While the cakes are baking, prepare the frosting. In a large bowl, beat together unsalted butter, Dutch-processed cocoa, vanilla extract, cream cheese, heavy whipping cream, powdered sugar, and salt until smooth and fluffy.
Step 8: Cool Cakes:
Allow the baked cakes to cool in the pans for 10 minutes, then transfer them to a wire rack to cool completely. This step is essential to prevent the frosting from melting when applied.
Step 9: Frost the Cake:
Once the cakes are completely cooled, frost between the layers and over the top and sides with the prepared chocolate frosting. Ensure an even and generous application for a decadent appearance.
Step 10: Make Ganache (optional):
For an optional ganache topping, heat heavy whipping cream until it simmers, then pour it over dark chocolate chips. Stir until smooth and glossy. Allow it to cool slightly before pouring it over the frosted cake.
Step 11: Chill (optional):
If the ganache is added, consider chilling the cake in the refrigerator for a short time to set the ganache, providing an additional layer of indulgence.
Step 12: Slice and Serve:
Finally, slice and serve this Costco-style chocolate cake. Enjoy the rich and indulgent flavors, perfect for gatherings or celebrations!
