Put banana and cherries in the food processor. Will yourself to walk away for about 2-3 minutes to let them lightly unthaw.

Add 1 Tbsp of the milk of your choosing

Turn the food processor on, and whip the mixture until it becomes light and fluffy. I like to whip mine for about 5 minutes - the volume should almost DOUBLE, and the mixture should be the consistency of light, airy soft-serve. You may need to add the remainder of the milk to get the consistency just right.

Place food processor bowl in the freezer for 5-10 minutes, if you can exercise that much will-power. This will allow the nice-cream to firm up, and be 'scoopable'. Can you tell I couldn't wait from my pictures?
