Step 1: Prepare Ingredients
Gather all the ingredients to ensure a tidy and smooth cooking process.
Step 2: Preheat the Oven
Preheat the oven to 350°F. Use cooking spray and flour on three 8-inch round cake pans.
Step 3: Melt the Chocolates
To melt the rich dark chocolate, start by using a heatproof bowl. Place the bowl in the microwave and heat the chocolate for 20-30 seconds, ensuring careful monitoring to prevent overheating. Alternatively, employ the double boiler method by situating the bowl over a pot of gently simmering water. Once melted, stir the chocolate until it achieves a smooth consistency, and then set it aside to cool slightly before incorporating it into your recipe.
Step 4: Prepare the Dry Ingredients
In a generously sized mixing bowl, sift together the dry components – the all-purpose flour, baking soda, baking powder, and a pinch of sea salt. This meticulous step ensures an even distribution of leavening agents, guaranteeing a uniform rise.
Step 5: Prepare the Wet Ingredients
In a separate bowl combine – granulated sugar, eggs, vanilla extract, and vegetable oil. Mix these ingredients until it becomes well combined. Gradually add melted chocolate into this mixture, stir until a silky smoothness appears.
Step 6: Combine the Wet and Dry Ingredients
Gradually add dry ingredients to wet ingredients, along with buttermilk. Start and end with dry ingredients, mixing each addition just until combined. Then add brewed coffee to the batter, mixing until smooth to enhance the chocolate flavor.
Step 7: Fill the Cake Pans
Divide the batter evenly among the 3 greased cake pans (8 inch). Pour the batter into each pan about 3/4 full so the cake won’t rise too much; and you don’t have to worry about them overflowing.
Step 8: Bake the Cakes
Bake the cakes for 20-25 minutes, or until a toothpick inserted in the center comes out clean.
Step 9: Cool, Decorate and Enjoy
Let the cakes cool in the pans for 10 minutes, then turn them out onto a wire rack to cool completely.
Step 10: Frost the Cakes
In a separate bowl beat the butter and cream cheese for about 2 minutes. Then slowly add the sifted powdered sugar and cocoa powder intermittently with the heavy whipping cream. Add the vanilla, salt and other ingredients.
Add more cream as needed to get a soft consistency. Beat the frosting for about 2 to 3 minutes until it becomes smooth and thick. Then transfer them into a piping bag, and decorate the cake as your choice.
– Make sure to use room temperature ingredients for best results.
– If the cakes are domed on top, use a serrated knife to level them before frosting.
– To prevent the cakes from sticking to the pans, make sure to grease and flour them before pouring in the batter.
– To make sure the cakes are cooked through, insert a toothpick into the center of each cake. If it comes out clean, the cakes are done.
– For a more intense chocolate flavor, add a tablespoon of cocoa powder to the buttercream frosting.
