The Ultimate Chocolate Cake

For the Cake:
1. Preheat your oven to 350°F (175°C). Grease and flour three 9-inch cake pans.
2. In a large mixing bowl, combine the flour, sugar, cocoa powder, baking soda, baking powder, and salt.
3. Add the eggs, buttermilk, warm water, vegetable oil, and vanilla extract to the dry ingredients. Mix until well combined.
4. Divide the batter evenly between the prepared cake pans.
5. Bake in the preheated oven for 30 to 35 minutes, or until a toothpick inserted into the center of the cakes comes out clean.
6. Allow the cakes to cool in the pans for 10 minutes, then remove them from the pans and transfer to a wire rack to cool completely.

For the Chocolate Cream Cheese Buttercream Frosting:
1. In a large mixing bowl, beat the butter and cream cheese together until smooth and creamy.
2. Add the cocoa powder and vanilla extract, and mix until well combined.
3. Gradually add the powdered sugar, one cup at a time, beating well after each addition.
4. If the frosting is too thick, add milk, a little at a time, until you reach your desired consistency.

Assembly:
1. Once the cakes are completely cooled, place one layer on a serving plate or cake stand.
2. Spread a layer of frosting over the top of the cake.
3. Repeat with the remaining layers, stacking them on top of each other and frosting between each layer.
4. Use the remaining frosting to cover the top and sides of the cake.
5. Decorate as desired.

Enjoy the most amazing chocolate cake ever!
