These are so much fun to make when your daughter has a slumber party or the boys have pals over for video game night. Roll them in sprinkles for the holidays, or add food color to the filling to match your favorite team for the big game! No matter what you decide, they're sure to be a fun dessert that will make everyone feel like a kid again!
