Instructions

1. Prepare the Oven and Pans
2. Preheat your oven to 350°F (175°C).
3. Grease and flour two 9-inch (23cm) round cake pans or line them with parchment paper for easy removal.
4. Make the Cake Batter
5. In a large mixing bowl, whisk together the flour, sugar, cocoa powder, baking soda, baking powder, and salt until evenly combined.
6. In a separate bowl, beat the eggs lightly, then whisk in the buttermilk, coffee, vegetable oil, and vanilla extract.
7. Gradually add the wet ingredients to the dry ingredients. Use a whisk or a hand mixer on low speed to combine, being careful not to overmix. The batter will be thin, which is normal.
8. Bake the Cakes
9. Divide the batter evenly between the prepared cake pans.
10. Bake in the preheated oven for 30–35 minutes or until a toothpick inserted into the center comes out clean.
11. Allow the cakes to cool in the pans for 10 minutes, then transfer them to a wire rack to cool completely.
12. Make the Cocoa Frosting
13. In a large bowl, beat the softened butter on medium speed until creamy and fluffy, about 2–3 minutes.
14. Gradually add the powdered sugar and cocoa powder, alternating with the heavy cream, beating on low speed after each addition.
15. Once all ingredients are added, increase the mixer speed to medium-high and beat for another 2–3 minutes until the frosting is light and spreadable.
16. Add the vanilla extract and a pinch of salt, and beat for another 30 seconds. If the frosting is too thick, add more cream, 1 tablespoon at a time, until you reach the desired consistency.
17. Assemble the Cake
18. Level the tops of the cake layers with a serrated knife if needed.
19. Place one cake layer on a serving plate or cake stand. Spread a generous amount of frosting evenly over the top.
20. Place the second cake layer on top, and frost the top and sides of the cake. Use an offset spatula for a smooth finish.
21. Decorate and Serve
22. Decorate the cake as desired. You can pipe additional frosting, sprinkle chocolate shavings, or add fresh fruit.
23. Allow the cake to sit for at least 30 minutes before slicing to let the flavors meld.

Tips for Success

Room Temperature Ingredients: Using room-temperature eggs and buttermilk ensures a smooth batter.

Brewed Coffee: Coffee enhances the chocolate flavor without making the cake taste like coffee. Substitute with water if desired.

Sifting Dry Ingredients: This prevents lumps in the batter and ensures a tender crumb.

Cooling the Cakes: Ensure the cakes are completely cool before frosting to prevent the frosting from melting.

Storage: Store the frosted cake in an airtight container at room temperature for up to 2 days or refrigerate for up to 5 days.

Optional Variations

Nutty Twist: Fold chopped toasted nuts into the frosting for added texture.

Flavored Frosting: Swap the vanilla extract in the frosting with almond or orange extract for a unique flavor profile.

This chocolate buttermilk cake is an irresistible combination of rich flavors and a soft, moist texture. Whether it’s for a birthday, a special gathering, or simply a treat-yourself moment, this recipe is sure to become a favorite. Enjoy!
