Frankenstein cookies, also known as monster cookies, are a type of oatmeal cookie that typically includes a variety of mix-ins such as chocolate chips, peanut butter chips, butterscotch chips, M&M’s, and nuts. They are a popular treat around Halloween due to their “monstrous” appearance.
The origin of the name “Frankenstein cookie” is uncertain, but it is thought to be a reference to the novel Frankenstein by Mary Shelley. In the novel, the monster is created from a variety of body parts, which is similar to the way that Frankenstein cookies are made from a variety of ingredients. Frankenstein cookies are a popular treat because they are easy to make, delicious, and fun to look at.
