Peel the bananas, slice them and place on a baking sheet in one layer. Place in the freezer for 1 hour.
After the hour, place the bananas in the food processor.
Blend the bananas for 2 to 3 minutes, until the mixture becomes completely smooth and creamy. It may be necessary to scrape the edges of the food processor with a spatula after a minute, until all the pieces are well incorporated into the mixture. It's ready when the mix really looks like soft ice cream.
Once everything is well-combined place the ice cream in a bowl and add the chocolate chips, mix a little more.
You can enjoy the ice cream right away or transfer it to a resealable container and put in the freezer for later.
