Why Is It Called A Monster Cookie?
Monster cookies are called so because they are large, hearty cookies with a variety of ingredients mixed into it. Typically made with oats, peanut butter, chocolate chips, and M&Ms, these cookies are “monster-sized” and packed with energy for adventurous activities like hiking or camping. The name ‘monster cookies’ may have also come from their tendency to spread and expand while baking, making them look huge.
