In my mind, the bananas count as a serving of fruit and I serve it over plain yogurt instead of ice cream, so I enjoy it pretty much guilt-free.
This is for a single hefty serving.
Start with 1 tablespoon of butter, 2 tablespoons of brown sugar, 2 tablespoons of chopped nuts (I usually use walnuts), and cook until the butter melts.
Pour 3 to 6 tablespoons of rum into a small bowl. Remove the butter mixture from the heat and add the rum. When you put the pan back onto the heat, step back. It's gorgeous, but hot and dangerous. (hey that sounds like me,...okay, okay, sorry, back to the dessert). The reason you pour the rum from the big bottle into a separate bowl is so that you don't inadvertently create a molotov cocktail, sending the entire bottle of rum up in flames. (I agree that's probably not necessary, but I can't help myself).
When the flames die down, add the banana chunks.
Stir and just warm the bananas. Then serve over ice cream or yogurt. Super yummy.
This is where I'm partying:
