That's how a chocolate cake should be: Moist, fluffy and chocolatey. Add a sweet and creamy pumpkin frosting to that and you got yourself a great cake for fall!
In case you don't like or have pumpkin purée you can also use a baked sweet potato and blend it up.
If you want to use a larger cake pan, keep in mind that the cake will be flatter and it will be harder to cut it in half.
