Peel and slice the bananas into coins. Transfer them to a freezer bag and put them in the freezer for at least 4 hours (or until they are frozen).
Once your bananas are frozen, transfer them to a blender, add the carob and blend until you get a homogenous mix. If your blender is having a hard time processing the frozen bananas add one or two teaspoon water.
Optional (only for non AIPers): if you want to add a little crunch to your nice cream, crush roughly your pecan nuts and add them to your nice cream. You can either simply sprinkle the pecan nuts on top of your nice cream or incorporate them in the nice cream by mixing with a spoon (don't use the blender or you will loose the crunchiness).
You can serve your nice cream right away when it has a soft serve consistency. Or if you want a scoop-able consistency, transfer your nice cream to a freezer safe dish and place in the freezer for about 2 hours. And voilà!Bon appétit!
