Take 2 bananas, cut and freeze for an hour or two. Throw in a food processor and whiz it around for a minute. Scrap sides. Add a tablespoon of peanut butter (I used all natural honey-nut). Whiz again. Serve.
It really tastes like soft serve, and surprisingly isn’t overwhelmingly banana-y. Best of all, H loves it, and I really don’t feel at all bad letting him eat it.
