Ahhh, Milk & Cookie Dough. Just like Grandma used to make. If your Grandma had a masters in human nutrition, was Director of The Sleep and Health Research Program at the University of Arizona, a Diplomate of the American Board of Sleep Medicine and a Fellow of The American Academy of Sleep Medicine
Also, if Grandma spent nine years as the Director of Education and Training at the Sleep-Wake Disorders Center at Weill Cornell Medical College, Sleep Advisor to the International Olympic Committee, and was known to millions as The Sleep Doctor, appearing regularly in the national media educating the media and consumers about sleep.
And, if she was able to figure out how to make a cookie dough ice cream that's as delicious as any other, but with like 70% fewer calories, about 65% less sugar, and 50% more protein, but without sweetening with anything artificial or wierd-tasting sugar alcohols.
Dude, your grandma sounds awesome!
