Slice about 4-5 bananas and freeze it covered with plastic wrap for at least 1 hour.
Place frozen bananas, peanut butter and almond milk in a high-speed blender, blend on high until a smooth consistency has formed. If the mixture is too thick, add a little bit more almond milk, add chips and blend one more time to combine.
Transfer it to a parchment-lined bread pan and freeze for about 1-2 hours.
