There are 36 cookies in a standard 14.3-ounce package of Oreo cookies. The bigger, 19.1-ounce package for a family has 48 cookies. The smaller 2-ounce package for one person has six cookies in it.
Oreo sometimes changes the size of the packages of cookies it sells. On the front of each single-serving package, the number of cookies inside is written in a clear way. For larger packages, you can figure out how many cookies are in the whole thing by looking at the nutrition label on the back of the packaging. One serving size is three cookies. On the nutrition label, the number of servings per package is listed. Multiply that number by three to find out how many cookies are in that package.
