Recipes for Bacardi rum cake originally used Bacardi Ocho. A deep, layered, and mellow flavor and notes of spices, oak, and dried fruits are present in this golden rum. You may also use Bacardi spiced rum or Bacardi Oro as alternatives, depending on the brand. Depending on what I'm drinking, any golden or dark rum will work! Whether you like the taste or not is what matters. According to my rule, you'll love the flavor of a cake if you enjoy it in a cocktail. However, my preferred rum is Bacardi Black. Among all the Bacardi rums, it's the sweetest!
