How to Order Starbucks’s Secret Peanut Butter Cup Frappuccino.

Starbucks does not officially have a “Secret Peanut Butter Cup Frappuccino” on their menu, but it is possible to order a custom drink that mimics the flavor of a peanut butter cup.

Here’s how to order the drink:

1. Start by ordering a Java Chip Frappuccino. This blended drink contains coffee, chocolate chips, and a mocha sauce.
2. Ask the barista to add peanut butter flavor to the drink. You can do this by asking for a pump or two of Starbucks’s peanut butter syrup in their Peanut Butter Cup cookie.
3. If you want the drink to be extra chocolatey, ask the barista to add mocha drizzle on top of the whipped cream.
4. Finally, you can add a sprinkle of sea salt on top to enhance the flavor of the peanut butter and chocolate.

Remember, custom drinks can be a bit more complicated to make, so it’s always a good idea to be patient and polite with your barista. You should also be aware that the cost of a custom drink may be higher than a regular menu item, as each ingredient added to the drink will increase the price.
