This rich and moist chocolate cake is the ultimate indulgence. Paired with a decadent cocoa buttercream, it's perfect for celebrations or just because.
Preheat oven to 350°F. Grease and line two 9-inch round cake pans.
In a large bowl, whisk together flour, cocoa, sugar, baking soda, baking powder, and salt.
In another bowl, whisk eggs, buttermilk, oil, and vanilla.
Add wet ingredients to dry, then stir in hot coffee. Batter will be thin.
Divide between pans and bake for 30–35 minutes, until a toothpick comes out clean.
Cool completely before frosting.
For the frosting, beat butter until fluffy. Add cocoa powder.
Slowly add powdered sugar, alternating with heavy cream. Add vanilla and salt.
Frost between layers and over the top and sides. Serve and enjoy!
Notes
For even layers, weigh your batter before pouring into pans. Store at room temp up to 2 days, or refrigerate for 5. You can freeze unfrosted cake layers for up to 3 months.
