Sandra’s Tips

  • It is important to glaze the rum cake while it is still warm. I find it is best to prepare the glaze in the final few minutes of the cake baking
  • A rum cake is traditionally baked in a bundt pan but you can use a 9 X 13 pan for easier preparation. Be sure to reduce the baking time to 25 minutes checking for doneness with a toothpick
  • Use real rum for the rich authentic batter flavor
  • Allow the cake to cool completely at room temperature to allow the glaze to set
  • You can serve it topped with whipped cream

Storage instructions

The rum cake can be stored in an airtight container at room temperature for up to 5 days.

Freeze rum cake by wrapping a portion a in double layer of plastic wrap then wrap it in foil. Freeze for up to 3 months. Thaw in the fridge overnight.
