Ingredients You’ll Need
For the Cake:
- 1 ¾ cups all-purpose flour
- 2 cups granulated sugar
- ¾ cup unsweetened cocoa powder
- 2 tsp baking soda
- 1 tsp baking powder
- 1 tsp salt
- 1 cup buttermilk (room temperature)
- ½ cup vegetable oil
- 2 large eggs
- 2 tsp vanilla extract
- 1 cup hot strong coffee (or hot water)
For the Frosting:
- 1 cup unsalted butter (softened)
- ¾ cup unsweetened cocoa powder
- 4 cups powdered sugar
- ¼ cup heavy cream (plus more if needed)
- 2 tsp vanilla extract
- Pinch of salt
Kitchen Equipment You’ll Need
- Two 9-inch round cake pans
- Mixing bowls (one large, one medium)
- Electric mixer or stand mixer
- Measuring cups and spoons
- Whisk
- Rubber spatula
- Wire cooling rack
- Offset spatula (for frosting)
- Cake plate or stand
Step-by-Step Instructions
1. Preheat and Prepare
Preheat your oven to 350°F (175°C). Grease and flour two 9-inch round cake pans or line them with parchment circles for easy release.
2. Make the Cake Batter
In a large bowl, whisk together the flour, sugar, cocoa powder, baking soda, baking powder, and salt. Add the buttermilk, oil, eggs, and vanilla extract. Mix until fully combined. Slowly pour in the hot coffee and stir until the batter is smooth. It will be quite thin—this is key for a moist, tender crumb.
3. Bake
Divide the batter evenly between the two pans. Bake for 30–35 minutes, or until a toothpick inserted into the center comes out clean. Cool the cakes in the pans for 10 minutes, then transfer to a wire rack to cool completely.
4. Make the Frosting
In a medium bowl, beat the butter and cocoa powder together until creamy. Gradually add in the powdered sugar, alternating with the heavy cream to reach a fluffy, spreadable consistency. Add the vanilla extract and a pinch of salt to balance the sweetness.
5. Assemble the Cake
Place one cake layer on your serving plate. Spread a generous amount of frosting on top. Add the second cake layer and frost the top and sides until fully covered. Smooth it out or swirl for a rustic finish.
Optional Decoration:
Top with chocolate shavings, a ganache drizzle, or fresh berries for a sophisticated touch.
Tips and Tricks for Perfect Results
- Use room temperature ingredients: This helps everything mix more smoothly for a better texture.
- Don’t skip the coffee: It enhances the chocolate flavor without making the cake taste like coffee.
- Cool completely before frosting: Otherwise, the frosting may melt or slide off.
- Make ahead: The cake layers can be made a day in advance. Wrap them tightly in plastic wrap and store at room temperature or refrigerate.
Variations and Swaps
- No buttermilk? Use 1 cup milk + 1 tbsp white vinegar or lemon juice. Let it sit for 5 minutes before using.
- Gluten-free: Substitute a 1:1 gluten-free flour blend.
- Add-ins: Mix in mini chocolate chips, a swirl of caramel, or chopped nuts for extra flair.
- Vegan version: Use plant-based milk + vinegar for buttermilk, vegan eggs (like flax eggs), and a vegan butter substitute for the frosting.
Storage and Leftovers
Room Temperature: Store the frosted cake in an airtight container for up to 3 days.
Refrigerator: Lasts up to 1 week in the fridge. Let it come to room temperature before serving for the best texture.
Freezer: The unfrosted cake layers freeze beautifully. Wrap in plastic wrap and foil, and freeze for up to 3 months. Thaw overnight before frosting.
Perfect Pairings
- Drink it with: A bold cup of espresso, a glass of red wine (like Cabernet Sauvignon or Merlot), or even a splash of Bailey’s for an extra-indulgent moment.
- Serve alongside: Vanilla bean ice cream, whipped cream, or fresh raspberries for contrast and balance.
Frequently Asked Questions
Can I use water instead of coffee?
Yes! While coffee deepens the chocolate flavor, hot water will still work fine. Just make sure it’s very hot, which helps bloom the cocoa.
Can I make this as a sheet cake?
Absolutely. Pour the batter into a 9×13-inch pan and bake for about 35–40 minutes. Check for doneness with a toothpick.
My frosting is too thick. What can I do?
Add a tablespoon of heavy cream at a time until the consistency is fluffy and spreadable.
Can I frost the cake while it’s warm?
It’s best to let the cake cool completely. Otherwise, your frosting will melt and slide off.
How do I get my cakes to come out of the pans easily?
Make sure to grease and flour your pans or use parchment paper circles at the bottom. Let the cakes cool in the pans for 10 minutes before flipping them out.
