E.L. Fudges are human cookies shaped like elves. It is due to this quality that they are liked by Keefe. Most cookies have the elves' names on the cookies (Ernie, Fast Eddie, Buckets, Elwood, and so on). They exist in the real world and the KOTLC Universe.
In the first book, Sophie's mom brought her some E.L Fudges the night Fitz had shown her the elvin world. In Legacy, Keefe begs Sophie for E.L Fudges after learning they are shaped like Elves. Sophie gets them for him when she gets her memories back with Amy, who gave them to her. Keefe was disappointed at the taste but adored the names of the Elves. Keefe acknowledges that Elwood (the cookie) looks like him, Sophie agrees to say, "He has your smirk."
