I've never actually had Bananas Foster before (it's on my list of things to experience) but I got this recipe from the restaurant that claims to have invented the dish so I would hope it was accurate. I'm just posting the ingredients list here since the steps don't apply.
I put in one banana, some milk (eyeball it), somewhere around two teaspoons of brown sugar (be generous, it's delicious), maybe a half teaspoon of cinnamon, and a shot of rum in the blender, along with a few ice cubes and blended until it was smooth. It shouldn't take that long. Pretty much as soon as the ice is blended it's done. You should have about a serving and half... or one serving if you're greedy like me.
I wish I had something to use as a garnish to make it more attractive but just trust me, it was delicious. I'm not going to claim this tastes like Bananas Foster, since I wouldn't know anyway but I fully enjoyed it. If you decide to give it a try let me know. Did you do anything differently? Do you have any other favourite boozy or banana themed desserts?
