Cookie

A cookie is a small, flat, sweet, baked good, usually containing flour, eggs, sugar, and either butter, cooking oil or another oil or fat. It may include other ingredients such as raisins, oats, chocolate chips or nuts.

Season two
Uncle Evan and Aunt Meg had Halloween-themed cookies out at the beginning of Mystery Inc.'s visit.

As Scooby-Doo was attempting to (secretly) break himself and the Secret Six puppies out of Scar and Skull's hideout, the puppies wandered off and found their way onto a table full of cookies, enjoying them greatly.
