I recently posted about trying a Butter Beer Latte from Starbucks' Secret Menu, well here is the Frappuccino version. I found this recipe too on the Starbucks Secret Menu, you should order one on your next visit to Starbucks.
This is for a Grande
Start with a Creme Frappuccino base (I used the vanilla bean one) - DO NOT skimp on the milk, you want to use whole milk for this one.
3 pumps caramel syrup
3 pumps toffee nut syrup
Top with whip cream
Drizzle with caramel syrup
