The Ultimate Shamrock Shake Copycat Recipe

Share the love :)

I can remember the cold winters growing up in Northern Virginia. I always looked forward to March when the weather began to warm in the South, and Spring for me officially started when I got my first taste of McDonald’s Shamrock Shake. Now that I am older, I rarely order anything from McDonald’s, and I do miss my green minty shake. To celebrate the art of adulting, I perfected the Shamrock Shake Copycat Recipe.

The start of Irish season is February 15th

We are about 6 weeks away from St. Patrick’s Day. However, February 15th is the official start of  Irish season when McDonald’s will bring back its famous, most celebrated treat – The Shamrock Shake. This shake has a cult following – there’s an unofficial Facebook page with over 35,000 fans and has its own mascot – meet Uncle O’Grimacy.

The origin of the Shamrock Shake

The Shamrock Shake was first sold in a Connecticut McDonald’s in 1970’s as the St. Patrick’s Day shake. The original recipe was vanilla ice cream with lemon-lime sherbet. It wasn’t until 1983 when the lemon-lime flavor was dropped and the mint flavor took over. Since it’s debut in 1970, McDonald’s has sold over 65 million shakes with only the McRib surpassing the shake sales seasonally. However, did you know that the Shamrock Shake is not available in all cities and McDonald’s stores across the country?

The key to the perfect Shamrock Shake Copycat

So while I love occasionally indulging in a thick and creamy McDonald’s shake, it’s still McDonald’s, which can only mean it’s loaded with sugars and others ingredients no human can pronounce. I have perfected the Shamrock Shake Copycat Recipe. In my opinion, the key is using a really good vanilla bean simple syrup (and mint extract – NOT peppermint extract). I make my own vanilla simple syrup. It’s very easy to make and to me it makes a big difference between the shake tasting authentic versus manufactured. I make the simple syrup a day or two before the shake, the syrup will keep in the refrigerator several weeks.

And as stated above, the other key to the Shamrock Shake Copycat Recipe is using mint extract, not peppermint, not spearmint. Pure mint extract is a combination of both peppermint and spearmint oils, the peppermint with a strong minty flavor whereas spearmint is subdued, and on the savory side. The McDonald’s Shamrock Shake is neither peppermint-y nor spearmint-y, but instead a minty mix of the two.
