It tastes just like a Wendy's Frosty. I buy the powdered whole milk (in a can in the Mexican section at Walmart). It tastes just like whole milk in the carton when mixed with cold water. Gives a rich taste to these if you aren't looking for non fat. If you don't have corn oil, use a light oil with no taste. Olive oil won't do in these. The spray of the non stick has to be used to make it creamy.
