    RUM CAKE TIPS

    • If you don’t have a bundt pan on hand, feel free to use a different shaped cake pan. Just make sure to look up a pan conversion chart to ensure that it is the right size!
    • Let the cake sit for 1-2 hours at room temperature before slicing and serving. This allows the flavors to fully absorb in the cake and leads to the best flavor!
    • Be sure to use fresh pecans for the best taste, flavor, and texture. However if pecans aren’t your thing, feel free to use walnuts or another preferred nut!
    • Depending on how much rum flavor you want in your cake, you can use light rum for a less intense flavor, and dark rum for a richer flavor. You can also decrease or increase the amount of rum in the cake before baking.

    WHAT OTHER FLAVORS OF CAKE MIX CAN I USE FOR RUM CAKE?

    We love using yellow cake mix for this recipe, but you can absolutely try other cake flavors if you would like! Chocolate, red velvet or Devil's cake mix also provide rich, amazing flavors that are sure to please!

    WHAT OTHER TOPPINGS CAN I ADD TO A RUM CAKE?

    There are lots of options for additional ways to top this rum cake. Try some fruits such as strawberries or raspberries, powdered sugar, whipped cream, ice cream, or chocolate drizzle.

    HOW DO YOU STORE RUM CAKE?

    Store any leftover rum cake in an airtight container at room temperature for up to 10 days. The rum acts as a preservative for the cake, so there is no need to worry about refrigeration!
