Step-by-Step Instructions
Prepare the Cake Pans
Preheat your oven to 350°F (175°C).
Grease two 8-inch round cake pans.
Line the bottoms with parchment paper.
Lightly grease the parchment as well.
This makes removing the baked cakes much easier.
Combine the Dry Ingredients
In a large mixing bowl, whisk together the flour, sugar, cocoa powder, baking powder, baking soda, and salt.
Break up any visible cocoa lumps.
Set the dry ingredients aside.
Add the Wet Ingredients
In a separate bowl, whisk together the eggs, buttermilk, vegetable oil, and vanilla extract.
Pour the wet mixture into the dry ingredients.
Mix gently until the batter is smooth and well combined.
Do not overmix.
Add the Hot Coffee
Slowly pour the hot coffee into the batter while whisking gently.
The batter will become quite thin.
This is normal.
The hot coffee helps bloom the cocoa powder and creates a deeper chocolate flavor.
Bake the Cakes
Divide the batter evenly between the prepared cake pans.
Bake for approximately 28–32 minutes.
Check the cakes by inserting a toothpick into the center.
It should come out with a few moist crumbs but no wet batter.
Do not overbake because this can make the chocolate cake dry.
Cool Completely
Remove the cake pans from the oven.
Allow the cakes to cool in the pans for approximately 10 minutes.
Run a thin knife around the edges.
Carefully turn the cakes onto a cooling rack.
Remove the parchment paper.
Allow the cake layers to cool completely before frosting.
Prepare the Chocolate Frosting
Place the softened butter in a large mixing bowl.
Beat for approximately 2–3 minutes until smooth and creamy.
Add the powdered sugar and cocoa powder gradually.
Mix on low speed at first to prevent the powdered ingredients from flying out of the bowl.
Add the heavy cream, vanilla extract, and salt.
Beat for another 2–3 minutes until the frosting becomes light and fluffy.
Add the melted chocolate.
Continue mixing until completely incorporated.
If the frosting is too thick, add another tablespoon of cream.
If it is too soft, add a little more powdered sugar.
Assemble the Chocolate Cake
Place the first completely cooled cake layer on a serving plate or cake stand.
Spread a generous layer of chocolate frosting over the top.
Smooth it evenly from edge to edge.
Place the second cake layer on top.
Press down very gently to secure the layers.
Spread frosting over the top of the cake.
Use an offset spatula to create smooth or decorative swirls.
Spread additional frosting around the sides if desired.
Create the Glossy Chocolate Finish
For an appearance similar to the pictured cake, keep the frosting slightly thick and create soft swirls across the top.
You can also warm a small amount of chocolate frosting for a few seconds and drizzle it lightly over the cake.
Allow the cake to rest for approximately 20–30 minutes before slicing.
Best Tips
Use room-temperature eggs and buttermilk for a smoother batter.
Do not overmix the batter after adding the flour.
The coffee does not need to be strong. Regular brewed coffee works perfectly.
Do not skip the parchment paper because it helps prevent the cake from sticking.
Make sure the cake layers are completely cool before adding the frosting.
For the cleanest slices, chill the assembled cake for approximately 30 minutes before cutting.
Best Ingredient Options
Cocoa Powder
Use unsweetened natural cocoa powder for a classic chocolate flavor.
Dutch-process cocoa can also be used, although it may slightly change the flavor and color.
Coffee
Hot brewed coffee intensifies the chocolate flavor.
If you do not want to use coffee, replace it with hot water.
Buttermilk
Buttermilk provides moisture and a subtle tang.
If you do not have buttermilk, combine 1 cup of milk with 1 tablespoon of lemon juice or white vinegar and let it stand for about 5 minutes.
Chocolate
Semi-sweet chocolate provides a balanced frosting.
Dark chocolate can be used for a more intense chocolate flavor.
Milk chocolate creates a sweeter frosting.
Recipe Variations
Triple Chocolate Cake
Add ½ cup of mini chocolate chips to the cake batter before baking.
You can also decorate the finished cake with chocolate shavings.
Chocolate Ganache Cake
Replace part of the frosting with a thin layer of chocolate ganache between the cake layers.
Pour additional ganache over the top for an extra glossy finish.
Chocolate Raspberry Cake
Spread a thin layer of raspberry preserves over the first cake layer before adding the frosting.
The tart raspberry flavor pairs beautifully with rich chocolate.
Chocolate Peanut Butter Cake
Add a thin layer of creamy peanut butter frosting between the cake layers.
Finish with chocolate frosting.
Extra Fudgy Chocolate Cake
Add a thin layer of chocolate ganache underneath the frosting.
This creates an especially rich and decadent dessert.
What to Serve With
Fresh strawberries and raspberries provide a bright contrast to the rich chocolate flavor.
A scoop of vanilla ice cream is another excellent option.
For a simple presentation, serve each slice with a small spoonful of whipped cream.
A cup of coffee or espresso also pairs beautifully with this chocolate dessert.
Make-Ahead Instructions
The cake layers can be baked one day ahead.
Allow them to cool completely before wrapping each layer tightly in plastic wrap.
Store them at room temperature for up to 24 hours.
The frosting can also be prepared ahead of time.
Keep it covered in the refrigerator and allow it to soften at room temperature before spreading.
Storage
Store the assembled cake in an airtight cake container.
It can be kept at room temperature for approximately 1 day if the environment is cool.
For longer storage, refrigerate the cake.
Allow refrigerated slices to sit at room temperature for approximately 15–20 minutes before serving for the softest texture.
Reheating
This cake does not need to be reheated.
For the best flavor and texture, serve it at room temperature.
If a slice has been refrigerated, simply allow it to sit out for a short time before eating.
Freezing
The unfrosted cake layers freeze particularly well.
Wrap each completely cooled layer tightly in plastic wrap, followed by aluminum foil.
Freeze for up to 2–3 months.
Thaw overnight in the refrigerator or for several hours at room temperature before frosting.
Individual frosted slices can also be frozen in airtight containers.
Common Mistakes to Avoid
Overbaking the Cake
Chocolate cake can dry out quickly if baked for too long.
Start checking the cake around the 28-minute mark.
Overmixing the Batter
Mix only until the ingredients are combined.
Overmixing can produce a denser cake.
Frosting a Warm Cake
Warm cake will melt the frosting.
Always allow the layers to cool completely.
Using Cold Butter for the Frosting
Cold butter will make the frosting difficult to whip smoothly.
Use softened butter for a creamy consistency.
Adding Too Much Liquid
Add cream gradually when adjusting the frosting.
A small amount can dramatically change the consistency.
