A box of algae cakes

Algae cakes were a health snack made by Ernest Philpott during the 1931 Hill Valley Science Expo. They were made in order to make the consumption of algae more pleasant (due in part to sweetening it up with corn syrup).[1] They didn't catch on and were not being made as of 1986[2].

Aside from the less than popular taste, eating an algae cake resulted in the person's teeth temporarily turning green. Despite being called cakes, they looked like cookies.

During October 12, Marty obtained some algae cakes at Hill Valley High School from Cue Ball (who ate some that fell off a truck). Despite being the one who made them, Ernest found the taste to be horrible when Marty offered him one.

The next day, Ernest passed out free algae cakes to those attending the Science Expo, except for Marty (who stole a box when Ernest was on stage).

In 1931A, Marty offered an elderly Edna Strickland the box he took before the timeline change, which she accepted (as she was the only known person to like them).

While they were not made in 1986B, the chemicals fed to patients of the Citizen Plus Program had a similar taste.[3]


  • While a box of the cakes read Oceanic Algae Cakes, Marty McFly read it aloud as Dr. Fringle's Algae Cakes.
