Was the Chocolate Chip Cookie an Accident? Ruth Wakefield's Story
The famous story says Ruth Wakefield invented chocolate chip cookies by accident. In the 1970s she said she did it on purpose. The legend vs the record.
Video coming soonThe short answer
Ruth Wakefield and her husband Kenneth opened the Toll House Inn in Whitman, Massachusetts, in 1930. The popular story says she ran out of nuts or baker's chocolate and chopped up a chocolate bar expecting it to melt. In the 1970s Wakefield told interviewers she chopped the chocolate on purpose to give her guests something new. The recipe appeared in her 1938 cookbook, and in 1939 Nestlé agreed to print it on its chocolate in return for free chocolate for life.
- Wakefield studied home economics before running the inn's kitchen.
- The 1938 cookbook called it the Toll House Chocolate Crunch Cookie.
- In 1997 a third-grade class helped make the chocolate chip cookie the official state cookie of Massachusetts.
The story (transcript)
Narration from the episode, as it is spoken.
You pull a warm cookie off the tray. The chocolate chips are soft and gooey, but they kept their shape. Somebody planned that. Or did they?
So was the chocolate chip cookie an accident?
In nineteen thirty, Ruth Wakefield and her husband Kenneth bought an old house in Whitman, Massachusetts, and turned it into the Toll House Inn. Ruth had studied cooking in school, and her desserts were famous.
Here's the story everybody tells. One night Ruth ran out of nuts, or out of baker's chocolate, so she chopped up a chocolate bar, expecting it to melt. Surprise. Chocolate chips.
But in the nineteen seventies, Ruth told interviewers a different story. Her guests loved her nut cookie, and she wanted to give them something new. She said chopping the chocolate was on purpose.
So who's right? Nobody can go back and watch. The accident story is fun, and lots of people still tell it. But the one person who was in that kitchen said she meant to do it.
By nineteen thirty-eight, the recipe was in her cookbook, called the Toll House Chocolate Crunch Cookie.
In nineteen thirty-nine, Nestlé agreed to print her recipe on its chocolate. In return, Ruth got free chocolate for life.
Fun fact. In nineteen ninety-seven, a class of third graders helped make the chocolate chip cookie the official state cookie of Massachusetts.

Each source is listed with the facts we took from it.
How we checked this
What we simplified, hedged or left out, and why.
- The disagreement is presented fairly: the accident story is told first, in full, as "the story everybody tells" (it is also told by respected sources like Lemelson-MIT); then Ruth's own 1970s account; then "nobody can go back and watch", ending on the fact that the only eyewitness said it was deliberate. We do not call the accident tellers liars; the dough-courtroom ends with both sides sharing cookies.
- "Studied cooking in school": LOC says she studied home economics; WBUR says she taught it, Globe says Framingham Normal School cooking program. Narration keeps it to "studied".
- Invention year is uncertain (sources say 1930, the 1930s, or 1938), so narration says only "by nineteen thirty-eight, the recipe was in her cookbook", which LOC and The Henry Ford support.
- The "$1" payment is "supposedly" in the Globe and unconfirmed elsewhere, so it is left out. "Free chocolate for life" is from the Whitman Public Library archive record of the 1939 agreement.
