This is a banana soft serve ice cream neapolitan loaf.
Okay, this one doesn't really need a recipe. Blend banana's with nut milk for each flavor and layer and freeze one layer at a time. To save time I blended each layer up and put in separate containers and put them in the freezer for a few hours and then when it was very cold and starting to freeze I layered them and froze overnight. Very easy and not expensive.
