While you're frying up some eggs and bacon, we're cooking up something else: a way to celebrate today's food holiday.

Milkshake, rattle and roll - June 20 is National Vanilla Milkshake Day!

The milkshake as we know it was invented by a Walgreen’s employee in Chicago in 1922. He added two scoops of ice cream to a drink called a malted milk. Needless to say, the concept quickly caught on.

By then, vanilla ice cream had already been around for a while. Thomas Jefferson even penned his own ice cream recipe after bringing back vanilla from France in the 1780s.

Making a milkshake is easy, and usually only requires a few ingredients - so quality is key. Even Thomas Jefferson called for “good cream.” A good quality ice cream means you’ll have a thick, frothy milkshake that’s not watered down or icy. And while using fresh, homemade vanilla bean ice cream isn’t a must, it certainly is life changing.

The original milkshakes were actually milk-based alcoholic beverages. They were considered tonics or treats. Adding a liqueur like Kahlua or Bailey’s is a fun way to make a treat enjoyed by kids, adult-friendly. Just make sure you’re over 21.
