The cream filling is made from sugar, vegetable oils (like palm and/or canola oil), cocoa, high fructose corn syrup, and various other ingredients that contribute to its flavor and texture.

The cookies themselves are made from a dough that includes unsweetened chocolate, which contributes to the dark color and chocolatey flavor of the cookies. However, it's important to note that the amount of actual chocolate in Oreos is relatively small compared to the total volume of the cookie, as the primary ingredients are flour, sugar, and oil.
