I do this alot....I don't really measure. I cut up a banana add a little homeade s/f chocolate syrup and unsweetened almond milk. I just blend until it looks the right consistantcy. I only use 1 banana though.
Ok, I tried this. I don't like the color. And it had a funny taste. Almost like it had cinnamon in it????
I found a website that gave another way to make it: cut the bananas into 1 inch pieces and freeze them for 1 hour. Then chop them in a food processor with just enough milk to make it look like soft serve.
I made this today and it was fantastic! I used a small frozen banana, spoonful of dry sugar-free fat-free butterscotch pudding, spoonful of almond butter, and a spoonful of greek yogurt. Soooo delicious and rich!
