This really is fat-free ice cream...in my opinion, better than frozen yogurt because there is no tart taste. This recipe was inspired by a lot of people here who gave me ideas for substitutions and also Heather Feather, whose cookie dough ice cream recipe led me to the ratios of ingredients! Thanks to all! Even my kids love this...they think it tastes like Breyer's vanilla bean ice cream! Note: Freezing time is listed in cook time.
