The Original Twinkie Filling Was Banana: Twinkie History

The first Twinkie, made near Chicago in 1930, had banana cream filling, says the company. Why it switched to vanilla in WWII, and the shelf-life myth.

Major Orange and Princess Punch in the Food Stories episode "The banana in the snack cake" — A still from the episode. The video is coming soon to YouTube @wonderadeusa; the full transcript is below.

The short answer

In 1930 bakery manager James Dewar, near Chicago, filled small cakes with cream to keep idle strawberry-shortcake machines busy. He said the name came from a sign for Twinkle Toe Shoes. The company says the first filling was banana cream; during World War II shipping problems made bananas hard to get, and the filling switched to vanilla. Twinkies don't last forever: the stated shelf life was 26 days, then 45 days from 2013.

The idle machines only ran during strawberry season.
An NPR reporter kept a Twinkie about a year and a half; it turned hard as a rock.
Banana Twinkies came back for a while in the 2000s.

The story (transcript)

Narration from the episode, as it is spoken.

You unwrap a golden snack cake and bite into the cream. Vanilla. But it didn't start out vanilla.

So what was inside the very first Twinkie?

In nineteen thirty, near Chicago, a bakery manager named James Dewar noticed some machines sitting still. They made strawberry shortcakes, and they only got used when strawberries were in season.

So he filled little cakes with cream to keep them busy. He said the name came from a sign he saw for Twinkle Toe Shoes.

And the company says the first filling was banana cream.

Then came World War Two. Bananas cross the ocean by ship, and the war made shipping hard. The filling switched to vanilla. People liked it, and vanilla stuck.

Now, legend versus truth. Maybe you've heard Twinkies last forever. They don't. In twenty thirteen, the company said they'd stay fresh for forty-five days. Before that, the number was twenty-six.

A reporter at NPR kept one on a shelf for about a year and a half. It didn't fall apart. It turned hard as a rock.

Fun fact. Banana Twinkies came back for a while in the two thousands.

1. and NPR's year-and-a-half shelf test. We say "stay fresh for" (shelf life), not "safe to eat until".
Date and place: April 6, 1930 (often cited) vs November 1930 (UPI), and Schiller Park vs River Forest, so narration says "in nineteen thirty, near Chicago".
"Came back for a while in the two thousands": 2005 promotion, regular from 2007 until the 2012 bankruptcy.
