FAQs
1. Can I use a different brand of rum?
Yes! While Cruzan Rum gives a great flavor, you can use Bacardi Gold, Captain Morgan, or Myers Dark Rum.
2. What can I substitute for rum?
If you want a non-alcoholic version, replace the rum with rum extract (1 tbsp) + apple juice or water.
3. Can I make this cake ahead of time?
Absolutely! The cake actually tastes better the next day as the rum flavor deepens. Store it tightly wrapped at room temperature.
4. How do I prevent my bundt cake from sticking?
Make sure to grease and flour your bundt pan well, or use a baking spray with flour. Let the cake cool 10 minutes before removing it.
5. Can I add extra rum?
Yes! If you want a stronger rum flavor, you can increase the glaze rum to ¾ cup, but don’t overdo it, or the cake may become soggy.
