Slice the bananas into thick slices, about 3/4" thick. Set aside.
Scoop desired amount of ice cream into a bowl. Set aside.
Melt the butter in a large skillet over medium heat. Once completely melted, add the banana slices, making sure that a cut side is down. Allow to cook in the butter until the bottoms start to brown. Use tongs or a spatula to quickly flip the banana slices and cook the other side until brown. Once all banana slices are brown, slowly add the Amaretto and allow to cook until mixture starts to thicken and bananas start to caramelize. As soon as bananas are caramelized, pour them over the vanilla ice cream and serve immediately.
Notes
*Use bananas that have just turned yellow. Overripe bananas, like the ones you would use for banana bread, are too ripe and too sweet and will fall apart quickly in the pan.
