Instructions

  • Preheat your oven to 350°F (175°C). Grease and line a 9-inch round cake pan.

Notes

For a lighter version, replace half the oil with unsweetened applesauce.
To make it dairy-free, use plant-based milk and vegan chocolate.
This cake tastes even better the next day as the flavors blend.
