*I typically cut the bananas into 1/2-inch/1.3-cm slices because large frozen pieces can be hard to blend. Freeze the slices on a parchment paper-lined baking sheet in a single layer to prevent large clumps.
**Because the ice cream doesn't contain any emulsifiers or stabilizers, and is not churned, it gets harder and icier the longer it sits in the freezer. So, it's best consumed immediately or as soon as possible.
