This is the simplest frozen dessert in the KitchenSimplicity archive: frozen banana pieces whirled in a food processor turn thick, smooth and scoopable, much like soft-serve. Walnuts and chocolate chips stirred in at the end give it the banana, nut and chocolate mix that the nickname chunky monkey usually describes. There is no cream, no custard and no churning involved.
Make it as an after-school snack, a last-minute dessert, or any time a bunch of bananas is about to get too ripe. The only planning required is peeling and freezing the bananas ahead of time, so it is worth keeping a bag of sliced bananas in the freezer.
Tips
- Use bananas that are yellow with a few brown freckles. Very dark, overripe bananas taste strong and turn the ice cream grayish.
- Toasting the walnuts in a dry skillet for 3 to 4 minutes deepens their flavor; let them cool before folding them in.
- Leftovers freeze rock hard. Let them sit at room temperature for 10 minutes, or pulse briefly in the food processor, before serving.
- A high-powered blender works too; use the tamper and add a tablespoon of milk only if the blades stall.
