Step 1

Place the frozen bananas (and optional salt) in a food processor or a high-speed blender.

Step 2

Pulse until the bananas are broken into tiny bits. Scrape sides of container with a rubber spatula.

Step 3

Keep pulsing, stopping a few times to scrape down the container (keep going!) until the mixture has the velvety consistency of soft-serve ice cream (it will happen all of a sudden!).

Step 4

Eat immediately (soft-serve style) or pack into an airtight container and freeze until solid, if desired.
