What Rum To Use
For the best flavor in this Banana Rum Mug Cake, use a dark rum with rich, caramel and molasses notes. Here are a few good options:
⭐ Recommended Rums:
- Myers’s Dark Rum – Classic, widely available, and adds a deep, bold flavor.
- Goslings Black Seal Rum – Slightly sweet and full-bodied, great for desserts.
- Diplomático Mantuano – Smooth with hints of vanilla and spice, elevates the banana beautifully.
- Plantation Original Dark – Rich, with warm tropical notes that pair well with banana and chocolate.
- Mount Gay Eclipse (Barbados) – If you want something with Caribbean authenticity and lighter spice notes. (My personal favorite!)
Rum Tip:
Avoid using white or spiced rum for this recipe—they don’t offer the same depth and can alter the flavor balance. If you prefer a non-alcoholic version, substitute with 1 teaspoon of rum extract or vanilla extract.
