Ways to celebrate

The modern milkshake only exists because a Walgreens employee decided to drop ice cream into a standard malted milk drink in 1922 — within a year, every Walgreens in the country was selling his "double rich chocolate malt."

Make one properly

Celebrate by:

  • Making an actual chocolate milkshake with real ice cream instead of a fast-food version.
  • Trying it the old-fashioned way, with malted milk powder added in.
