Step 1: Make the Chocolate Cake
- Preheat oven to 350°F (175°C). Grease and line two 9-inch round cake pans.
- In a large bowl, whisk together flour, cocoa powder, sugar, baking powder, baking soda, and salt.
- Add eggs, buttermilk, oil, and vanilla. Beat until smooth.
- Slowly add hot water or coffee, mixing until fully incorporated. The batter will be thin.
- Divide between pans and bake 30–35 minutes, or until a toothpick comes out clean. Cool completely.
Step 2: Make the Chocolate Buttercream
- Beat softened butter until light and fluffy.
- Sift in powdered sugar and cocoa powder. Mix on low until combined.
- Add cream, vanilla, and salt. Beat on high until smooth and spreadable. Add more cream if needed.
Step 3: Assemble the Cake
- Level cake layers if needed. Place one layer on a cake stand or plate.
- Spread buttercream evenly, then top with the second cake layer.
- Frost the top and sides of the cake with remaining buttercream.
- Optional: Decorate with chocolate curls, sprinkles, or a ganache drizzle.
Chill & Slice
Let the cake rest for 30 minutes before slicing for cleaner cuts. Serve with cold milk or espresso for a true indulgence.
This Decadent Chocolate Cake delivers rich flavor, velvety texture, and pure chocolate satisfaction—perfect for birthdays, holidays, or any sweet celebration.
