This rich rum soaked cake is perfect for a cold winter evening. Enjoy it warm with a cup of hot tea for a cozy and relaxing holiday night. It is a special treat made easier by starting with a box cake mix. While white rum is sweeter, dark rum is recommended for baking this drunken cake due to its bold, aromatic flavor and spiced undertones. Using a dark rum will balance your flavors, while white rum may add too much sweetness to your already-sweet ingredients.
