Thin Mint Frappuccino

Thin Mint Frappuccino is a customized Matcha Green Tea Creme Frappuccino that became popular on social media, making it a secret menu item.

Secret menu drinks can’t be ordered by name since Starbucks baristas are trained to make them. To order a secret menu item, you’ll need to know the drink recipe, including all the ingredients and any specifications.

This drink can be ordered in person or via the Starbucks app because each customization is available on the app.

How It Tastes

Right from the first sip, it tastes like a drinkable mint chocolate chip cookie in a cup!

The mint taste is delicate with a stronger chocolate flavor which comes from the mocha syrup and Frappuccino chips. The matcha flavor is mild so the mint and chocolate are able to come through.

What’s In The DRink

  • Base drink: Matcha Green Tea Creme Frappuccino
    Each secret menu drink starts with an official Starbucks menu drink and this one is the Matcha Frappuccino.
  • Customizations for a grande drink: Remove Classic syrup, add 1 pump of mocha sauce and 1 pump of peppermint syrup, add java chips (Frappuccino chips), add mocha drizzle
    Swapping classic syrup for mocha and peppermint give this drink its “thin mint” mint and chocolate flavors. The java chips increase the chocolate flavor while adding bits of chocolate chips to give the drink a texture that’s fun to drink.

How to Order the Drink

“Can I get a grande Matcha Frappuccino with no classic syrup, 1 pump mocha, 1 pump peppermint, java chips blended in, and mocha drizzle on top?”

Drink Cost

A grande size of the Thin Mint Frappuccino costs $6.05 plus tax. Depending on which Starbucks you buy the drink from, the price will vary.

It was $4.95 for the Matcha Frappuccino, $0.60 for mocha sauce, no extra charge for peppermint syrup, $0.50 for Frappuccino chips, and no extra charge for mocha drizzle.

If a drink already comes with syrup and you replace it for another, Starbucks doesn’t charge extra. So for this drink, you are swapping classic for peppermint syrup.

Tip your barista if you can! Secret menu drinks take more time to make and your barista would definitely appreciated it!
